Gum bleeding is a common oral problem. About 80% of people worldwide have experienced or are experiencing gum bleeding. Apart from the effects of inappropriate cleaning utensils or overly hard food on the oral cavity, the main cause of gum bleeding is inflammation of the gums under the stimulation of bacteria, which makes the gums fragile and sensitive. Incorrect cleaning methods cause them to bleed at the touch. Teeth account for 25% of the entire oral cavity, and the rest is mucosal tissue. Gums are also one of the mucosal tissues. Teeth grow on the gums, just like flowers grow in the soil. In the case of bleeding gums, continuing to use incorrect oral cleaning methods will make the problem more serious, so the results will not meet expectations; to care for bleeding gums and restore the oral cavity to a dynamic and healthy state, you need to sterilize the gums, massage the gums, and reduce factors that irritate the gums. In overall oral hygiene, everyone should think that mouthwash is one of the long-term effective ways to kill bacteria, but mouthwash removes bacteria in a free state and has little effect on bacterial biofilms that have already adhered to the oral mucosa or teeth. Within a few hours after use, the bacteria will return to the level before use, and the timeliness is very short and irritating. But long-term use is not recommended. Excessive brushing can irritate and worsen gum damage, and it also fails to clean the bacteria on the gums. Long-term use of mouthwash can damage the oral flora and irritate the mucosa. Are there other safe, effective, and long-lasting products for cleaning the oral mucosa? TongueClear oral airbag brush can effectively remove bacterial biofilm on the gums by scraping with the airbag brush head. Bacterial biofilm has a certain stickiness and cannot be removed by ordinary mouthwash. The gentle and soft wiping of the airbag brush head will not only not damage the gum tissue, but also effectively peel off the adhered bacteria, remove food residues in the mouth, make the bacteria lose food, and find it difficult to reproduce, reduce the activity of bacteria and naturally die. It has little irritation to the mucosa. Unlike the hard texture of toothbrushes or tongue brushes, oral brushes are soft and tough, and the cleaning process is gentle with little foreign body sensation. It is also different from chemical mouthwashes for the purpose of inactivation. Physical cleaning is safer, more efficient, and longer-lasting.

Oral thrush, also known as oral candidiasis, is a common oral disease. It is caused by Candida infection and usually affects infants, the elderly, and people with weak immune systems. Especially among infants, many mothers are still immersed in the joy of the baby's arrival. Because the baby's mouth is very delicate, they are worried or afraid that cleaning will hurt the baby, so they will ignore oral hygiene, which will induce oral diseases such as thrush. But don't panic, we only need to understand the symptoms, causes, treatments and preventive measures of the disease, so that we can better manage oral health. What is thrush? Thrush is a disease caused by a fungal infection, most commonly caused by Candida albicans. This fungus is normally present in the mouth, but under certain conditions, it can overgrow and cause an infection. Typical symptoms of thrush include white spots in the mouth, pain, difficulty swallowing, and dryness in the mouth. Sometimes, the infection can also cause redness, swelling, and discomfort in other areas of the mouth. Causes of Thrush Thrush can be caused by a variety of reasons, usually due to the following:1. Low immunity: A weak immune system makes the body susceptible to infection.2. Antibiotic use: Antibiotics kill the beneficial bacteria in the mouth, allowing Candida to multiply rapidly.3. Diabetes: High blood sugar levels help Candida to grow, making diabetics more susceptible to infection.4. Poor oral hygiene: Lack of good oral care habits can lead to an imbalance of bacteria in the mouth, increasing the risk of infection. Although thrush is a common oral disease, it can cause great harm to the body if it is not treated in time. Therefore, once you find symptoms of thrush, you should go to the hospital in time and take effective treatment measures. How to treat thrush? If you have symptoms of thrush or suspect you have thrush, please see a doctor immediately. Treatment for thrush usually includes the use of antifungal drugs, such as fluconazole or clotrimazole. Maintain good oral hygiene and perform full oral cleaning regularly. It should be noted that brushing and flossing can only clean 25% of the oral area. The other 75% is made up of oral mucosa. Therefore, if you want to achieve true oral cleaning, you need to clean not only the teeth but also the oral mucosa. Only in this way can you effectively prevent reinfection and speed up recovery. At the same time, you should also reduce the consumption of irritating foods and keep your diet light. How to prevent thrush? The key to preventing thrush is to maintain oral health and good living habits. Here are some effective preventive measures:Regular oral cleaning: Brush your teeth at least twice a day and use dental floss to clean the residue between the teeth. At the same time, use oral mucosal cleaning tools to clean the oral cavity other than the teeth, so as to achieve true full oral cleaning, remove harmful bacteria, and maintain oral hygiene.Healthy diet: Maintain a balanced diet and reduce sugar intake to reduce the chance of Candida growth.Exercise and fitness: Exercise to enhance immunity and prevent infection caused by low immunity.Regular health checks: Especially for diabetics, regularly monitor blood sugar levels and maintain a healthy lifestyle.

 What are the types of gum disease and what are their symptoms? Gum disease is often silent and has no obvious symptoms in the early stages, so it is difficult to detect in the early stages, which means that symptoms may not appear until the later stages of the disease. Here are some common types of oral gum disease: Gingivitis: The mildest form of gum disease, usually caused by plaque accumulation. Symptoms of gingivitis include red and swollen gums, bleeding (especially when brushing), and bad breath. Periodontitis: Periodontitis is the advanced stage of untreated gingivitis. At this time, the inflammation will spread to the bones and tissues around the teeth, causing the teeth to loosen or even fall out. Symptoms include gum recession, persistent bad breath, loose teeth, abscesses, etc. Necrotic gingivitis: This disease is rare and usually occurs in people with weakened immune systems. Symptoms include severe gum pain, ulcers, necrosis and fever, which require emergency treatment. Gum recession: refers to the phenomenon that the gum tissue gradually recedes, exposing the tooth root. Under normal circumstances, the gums cover the root part of the tooth, but as the gums shrink, the root will be exposed. This situation not only affects the appearance, but may also lead to tooth sensitivity, increased risk of caries, and even loose teeth. How can gum disease be prevented? Relevant data research shows that if most oral diseases can be prevented early and good oral hygiene is maintained, the risk of oral diseases can be effectively reduced. The following are some common and effective prevention methods: Maintain good oral hygiene habits: The correct brushing method is the basis for preventing gum disease. Use a soft-bristled toothbrush to brush your teeth at least twice a day, and use dental floss to clean the gaps between teeth to remove physical debris in the gaps between teeth. Choose fluoride toothpaste and replace toothbrushes regularly. Adhere to good dental cleaning to help remove dental plaque and keep the mouth clean. Pay attention to mucosal cleaning: In addition to brushing and flossing, it is equally important to clean the oral mucosa (such as the tongue, under the tongue, inside the cheeks, and gums). Bacteria and food residues can also accumulate on the tongue coating. Using professional oral cleaning tools (such as oral mucosa cleaners) can help completely remove bacteria in the mouth and reduce the risk of gingivitis. Regular oral examinations: At least two oral examinations a year can detect and treat gum disease early. Dentists can perform professional dental cleaning to remove plaque and tartar and prevent further development of gum disease. Healthy diet and quitting smoking and limiting alcohol consumption: Healthy eating habits are also important for gum health. Reducing sugar intake helps reduce the formation of dental plaque. Smoking and excessive drinking increase the risk of gum disease, so quitting smoking and limiting alcohol consumption is essential for maintaining gum health.

Everyone may be familiar with sensitive gums. The gums or teeth will feel obvious soreness in hot or cold environments. Some friends will feel soreness, weakness in their teeth, and bleeding gums when eating hard or irregular foods. Gum sensitivity, which is caused by poor hygiene in the oral cavity, resulting in bacteria and food debris at the periodontium and mucous membranes to form a biofilm at the gingival margins and not properly and scientifically cleaned, leading to further bacterial damage to stimulate the gum tissues, causing redness and swelling of the gums, bleeding, receding gums, and other oral problems. Sensitive gums are one of the early warnings of oral problems. When you notice that your gums are reddish in color, have a noticeable indentation when pressed, and have a softer texture than normal gums, you should be concerned about whether or not your mouth is being properly cleaned. Ineffective oral hygiene is a key factor in causing gum sensitivity. Modern people's oral cavity is basically in a eutrophic state. The warm and humid overall environment allows bacteria to multiply and form biofilms attached to various parts of the oral cavity. A large number of bacteria survive and grow under the protection of biofilms. Uninterrupted biofilms will eventually lead to the formation of plaques, promoting the formation of tartar, demineralization, caries, gingivitis and periodontal disease. It threatens the overall health of the oral cavity because inflammation continues to irritate the gums. Therefore, frequent destruction of biofilms is essential to prevent plaque formation. Most people think that brushing teeth frequently can effectively clean the mouth, but brushing teeth can only clean teeth. The hardness of the toothbrush will cause wear on the teeth, and the greater the force applied, the more wear will be caused. However, even for well-trained people, brushing teeth cannot remove more than 40% of dental plaque. Moreover, incorrect brushing methods not only fail to clean teeth and mucosa, but also easily cause the gums to retreat toward the roots, making gum sensitivity more serious. In order to prevent gum sensitivity problems, other oral cleaning methods should be used to supplement brushing. Related studies have shown that although the combination of toothpaste and mechanical brushing can remove most bacteria in the mouth, tongue cleaning will further enhance the cleaning effect of brushing. However, the tongue cleaning methods are relatively limited, which causes the bacteria on the tongue to continue to multiply in the saliva. We cannot take out the tongue for cleaning at any time, but it proves from the side that cleaning methods similar to the tongue, such as wiping the oral mucosa with fingers, are crucial in reducing the overall bacterial load in the mouth. TongueClear starts from the cleaning concept theory of "frequent destruction of biofilms" and believes that oral cleaning must have the three characteristics of safety, effectiveness and long-term use. We only need to mechanically interfere with the formation of biofilms to reduce the early colonization of bacteria. Combined with relevant research, physical cleaning is the safest and most efficient way to effectively destroy biofilms. Based on this research, TongueClear combines the tongue with fingers that have similar characteristics to the tongue to develop an oral airbag cleaner with mucosal cleaning function. The oral airbag cleaner is made of food-grade silicone material, and the airbag brush head can cling to the inner wall of the mouth like a tongue or finger. The patented scraping integrated texture cleans the mucosa over a large area while massaging the mouth, improving blood circulation in the mouth, reducing symptoms of gum sensitivity, and enhancing the overall resistance of the mouth. On the basis of physical cleaning, TongueClear has developed an oral mucosal gel containing lysozyme and glycosidase as a supplement to oral physical cleaning. After physical cleaning, some residual bacteria still pose a certain threat to oral hygiene. Lysozyme can dissolve harmful bacteria without damaging the oral microecology and decompose the residual sugar in the mouth to achieve the purpose of destroying bacterial activity and living environment, and achieve safe, efficient and long-term cleaning at both the physical and biological levels of the oral cavity. Effective and scientific oral cleaning can effectively prevent diseases caused by oral hygiene problems. Gum sensitivity is a warning before the occurrence of oral diseases. Therefore, we must pay attention to oral cleaning and choose oral cleaning products that can be used for a long time, safe and effective.

Tooth decay is what we often call dental caries. It is a disease that causes progressive destruction of tooth hard tissues under the influence of multiple factors such as bacterial infection. Failure to receive timely treatment can lead to complications such as pulpitis, apical periodontitis, and even jaw inflammation. Bacteria are the main factor in the occurrence of dental caries. Cariogenic bacteria are often mainly Streptococcus mutans, Lactobacillus, and Actinomycetes (Streptococcus mutans can cause caries on the smooth surface of teeth, Actinomycetes can cause pit and fissure caries, and Lactobacillus accelerates the development of caries). With the change of modern dietary structure, food residues and lack of attention to oral hygiene have become the norm. The oral cavity is continuously in a state of eutrophication. The warm and humid environmental characteristics of the oral cavity allow bacteria to multiply in large numbers. Bacteria interact with each other to form biofilms, which provide living space and protection for bacteria. Bacteria then decompose food residues in the oral cavity to metabolize and feed back to the biofilm to make it stronger. The acidic substances in the metabolic process corrode and change the overall environment of the oral cavity, while causing the enamel to demineralize and dissolve to produce caries. Dental caries are common in people of any age after the eruption of deciduous teeth, and the main reason for the high incidence of dental caries is the lack of correct oral hygiene awareness and effective cleaning methods. Symptoms and Causes: What are the signs of cavities? Tooth decay on the outer enamel surface doesn’t usually cause pain or symptoms. You’re more likely to experience symptoms as decay reaches beyond the enamel into the dentin and pulp. Cavity symptoms include: Bad breath or a bad taste in your mouth. Bleeding gums or other signs of gum disease. Facial swelling. Toothache or mouth pain. Tooth sensitivity to hot or cold foods or drinks. How do you get rid of cavities? Tooth decay treatment depends on the severity of your condition. Cavity treatments include: Fluoride. Fillings. Root canal therapy. Tooth extraction. How can I prevent cavities? Proper oral hygiene, including regular brushing and flossing, can get rid of plaque, acids and cavity-causing bacteria. Good teeth and gum care includes: Brushing your teeth with a soft-bristled brush and fluoride toothpaste at least twice a day, and preferably after every meal. Cutting back on sugary, starchy foods and drinks. Daily flossing to get rid of food and plaque stuck between your teeth.

Pulpitis is one of the common oral diseases, accounting for about 10%-20% of the overall oral diseases. According to statistics from relevant international research institutions, it is more common among adults, especially those over 30 years old. As they age, their teeth become more susceptible to external stimuli and cause inflammation. At the same time, in some areas with backward sanitary conditions and weak oral protection awareness, the incidence of pulpitis is higher than that in European and American countries, accounting for 20% or more of local oral diseases. It is reported that poor oral hygiene habits are one of the biggest causes of pulpitis. The pulp is a loose connective tissue containing nerves and blood vessels, located in the pulp cavity inside the tooth. Pulpitis is caused by bacteria invading the pulp after the hard tissue of the tooth is destroyed by bacterial acid production or other reasons. Pulpitis generally has obvious spontaneous pain or occasional dull pain. When the pain occurs, it cannot be clearly pointed out where the affected tooth is. The pain often radiates to the upper and lower jaw teeth or head and face on the same side of the affected tooth. Some patients will also experience aggravated pain due to temperature stimulation, showing symptoms of "hot pain and cold relief". In addition to uncontrollable factors, such as the loss of tooth hard matter caused by eating hard and irregular foods, dental caries is the most common cause of loss of tooth hard tissue. Dental caries, commonly known as tooth decay, is a bacterial disease caused by the combination of Streptococcus mutans and other harmful bacteria to form a bacterial biofilm that corrodes teeth. Bacteria reproduce in the eutrophic and warm and humid environment of the oral cavity, decompose food residues to produce organic acids and ammonia, lower the oral pH environment, decompose tooth organic matter, decalcify and dissolve hard tissue, and gradually destroy the tooth surface, forming cavities and exposing the pulp. The prevention and improvement of pulpitis are closely related to oral hygiene. The mouths of modern people are often exposed to sweets and high-calorie diets. The residual food contains a large amount of carbohydrates and sugar, which continuously provide power for bacteria to continuously transform the oral environment, making the mouth in an acidic state suitable for their survival for a long time. With the accumulation of time, pulpitis breaks out due to the loss of tooth hard tissue and the proliferation of oral bacteria. It can be seen that the quality of oral hygiene is directly related to the incidence of pulpitis, and the most direct way to improve oral hygiene is brushing teeth and cleaning mucosa, but common cleaning methods are basically concentrated on teeth cleaning, and the methods for mucosal cleaning are few, single and ineffective, and cannot deeply destroy the bacterial biofilm. Oral bacteria that are not properly cleaned will fill the entire mouth again in just a few hours. The reciprocating mechanical toothbrushes we are familiar with can only destroy and remove bacterial biofilms attached to teeth, but there has been no scientific cleaning method in the field of oral mucosa. TongueClear starts from the concept of oral mucosa cleaning, sorts out and studies the characteristics of mucosa, and develops oral airbag cleaner and biotechnology oral mucosa gel that clean mucosa at the physical level. The oral brush uses a silicone airbag brush head, and Flexconform adaptive technology makes the mouthwash soft and tough enough to fit the human oral structure. The scraping integrated cleaning texture increases the contact area with the oral mucosa, and massages the inner wall of the oral cavity while scraping to promote blood circulation, enhance oral resistance and the health of the oral mucosa. The oral brush destroys the bacterial biofilm attached to the oral cavity by physical means and removes food residues. At the same time, the lysozyme and glycosidase in the mouthwash destroy the living environment of bacteria while eliminating pathogens, thereby achieving long-term, efficient and deep cleaning of the overall oral hygiene environment. Pulpitis is closely related to the oral environment and tooth hard tissues, but the loss of tooth hard substances is related to many factors. We cannot prevent foreign objects from damaging teeth, but we can control oral bacteria and biofilms, prevent early bacterial colonization and plaque formation of bacterial biofilms, and reduce damage to teeth caused by bacteria, thereby achieving overall prevention of oral problems.

Pericoronitis is a common oral disease worldwide, accounting for about 5%-15% of oral diseases. The onset of pericoronitis is mainly concentrated in the stage of tooth eruption, often occurring in the wisdom tooth eruption period of young people around 18-30 years old. The eruption of wisdom teeth is affected by the physiological characteristics and living habits of wisdom teeth. The incidence of pericoronitis in this stage is about 10%-20%. In developed countries such as Europe and the United States, due to the sound awareness of oral health care, their professional intervention in early prevention and intervention has made the incidence of pericoronitis in European and American countries relatively low. Pericoronitis is mainly manifested as inflammation of the soft tissue around the crown of the tooth. In the early stage of pericoronitis, the gums can be obviously painful and swollen, and local swelling due to inflammation may occur. The main treatment methods currently available are to control local bacterial infection and control oral hygiene while eliminating the infection. In the analysis of many cases of pericoronitis oral diseases, it was found that a small number of patients had pericoronitis due to bacterial infection caused by oral gingival tissue injury. Some patients had impacted wisdom teeth due to the physiological characteristics of wisdom teeth, which led to inflammation. In this case, surgery was required to remove the impacted wisdom teeth. However, oral hygiene is crucial in both the preoperative surgical environment and postoperative recovery. Putting aside the uncontrollable factors mentioned above, about 70% of the remaining pericoronitis patients have long-term accumulation of food residues around the crowns before the onset of the disease. In the eutrophic and warm and humid environment of the oral cavity, anaerobic bacteria, the main pathogens of pericoronitis, multiply in large numbers. Anaerobic bacteria use the bacterial residues in the mouth for metabolism and produce a large number of harmful metabolites, such as endotoxins, organic acidic substances, etc. The accumulation of acidic substances leads to a decrease in the pH value of the oral cavity, which has a comprehensive impact on the overall oral environment. At the same time, a large number of bacteria interact with each other in the mouth to form bacterial biofilms attached to the teeth, oral mucosa and other internal spaces of the oral cavity. The biofilm provides bacteria with a stable living environment to help them continuously release harmful substances, causing the gums and other tissues to be in a state of chronic inflammation, restricting local blood circulation, and reducing the resistance and self-healing ability of the gums. The biofilm can resist common oral cleaning methods. Damage to the oral mucosa and gums and periodontal tissues is inevitable. Whether it is gum damage during the eruption of wisdom teeth, picking teeth with a toothpick after meals, or eating hard, angular foods, it can easily cause damage to the fragile and delicate oral tissues. Ultimately, the occurrence of pericoronitis is also caused by poor oral hygiene and increased bacteria. For oral hygiene, we need to pay more attention to the cleaning of the mucosa.Good oral cleaning can prevent the occurrence of most common oral diseases. Maintaining correct cleaning habits can effectively prevent about 70% to 80% of oral diseases. However, the simple mechanical back-and-forth brushing behavior can only basically remove the biofilm and bacteria attached to the teeth, and the cleaning of the mucosa is basically zero. Oral mucosa occupies most of the space and area of the oral cavity, and is delicate and sensitive. Common cleaning methods generally have many limitations, and are often highly irritating and easily damage the mucosa. Most products are prone to damage the oral microecology. TongueClear has developed an oral airbag cleaner with Flexconform adaptive fitting technology at the physical level for the delicate oral mucosa. The patented texture of the scraping one-piece can maximize the contact area and massage the gums to promote blood circulation during use. The brush head is soft and elastic, comfortable to use, and has low foreign body sensation. It uses physical means to remove food residues and bacterial biofilms in the mouth. On the basis of physical cleaning, TongueClear has developed a oral mucosa gel made by biotechnology. The lysozyme and glycosidase contained in it can enzymatically hydrolyze a variety of pathogens in the oral cavity through biological enzymatic hydrolysis, decompose residual sugar in the oral cavity, destroy the living space of bacteria, and kill bacteria from the root. A variety of natural plant extracts can also nourish the beneficial bacteria in the oral cavity. Long-term use is safe and durable and will not damage the microecology in the oral cavity. This is why long-term and correct use of TongueClear can prevent pericoronitis. Prevention of oral diseases is better than cure, and oral hygiene is the basic link in the prevention of oral diseases. We must have a correct understanding of pericoronitis. Damage to oral tissue is inevitable, but we can kill bacteria by cleaning the mouth and reduce the risk of pericoronitis caused by a poor oral microenvironment. At the same time, a healthy oral microenvironment will also promote the self-healing of pericoronitis and the dissipation of inflammation.

According to the relevant report data released by the International Epidemiology in 2019, more than 80% of adults in the world have gum atrophy. It has become the most common oral disease for people born in the 1980s and 1990s. According to the WHO standards, the incidence of gum atrophy is about 10%. According to the latest data on gum atrophy in Germany in 2024, the incidence of gum atrophy is 3%-5%. Among the young and middle-aged people aged 35-44, about 83% of people have gum atrophy problems. When smiling, the terrifying "black triangle" of the periodontium is more eye-catching than the smile. The high symptoms of gum atrophy and the continuous addition of "new blood" clearly show that the phenomenon of gum atrophy is becoming more and more popular and younger. Although the data shows a trend of skyrocketing year by year, many friends still do not pay attention to it. They think that gum atrophy mostly occurs in middle-aged and elderly people, and it is not a big deal at present. What they don’t know is that oral hygiene is directly related to gum atrophy, but it is indirectly related to age. How to prevent gum atrophy from happening at a younger age? Gum atrophy refers to the exposure of tooth roots caused by the gums retreating to the root side of the enamel-cementum junction. It usually occurs in the gums near the lips and cheeks, and the symptoms of gum atrophy are often irreversible, so we should spend more time on the prevention and improvement of gum atrophy than on treatment. The cause of gum atrophy is simple. Some patients are induced by oral inflammation, and some patients are induced by periodontitis. The most common cause is the accumulation of foreign matter (tartar) at the gingival margin of the gums, which stimulates the gums. Some people, due to the increase of age, the decline of various functions, the decline of oral self-cleaning ability, and the inability to properly clean the mouth, lead to excessive bacterial reproduction and aggravation of oral inflammation. Under the multiple stimulations of inflammation and foreign matter, the degree of gum atrophy, which was not serious, continues to increase. It can be seen that the relationship between oral hygiene and gum atrophy is huge. Oral inflammation is caused by various pathogenic bacteria in the oral cavity. In the unfavorable environment of oral eutrophication and warm and humid conditions, they interact to form biofilms attached to various parts of the oral cavity, and they have not been properly and scientifically cleaned for a long time. Excessive bacterial accumulation leads to gum and periodontal inflammation. Dental plaque attaches to the root of the tooth and forms tartar after calcification, which continuously stimulates the gums and causes gum atrophy. How to clean your mouth correctly? Based on the delicate characteristics of oral mucosa, TongueClear analyzes the characteristics of people with oral problems. From the perspective of efficient and safe oral cleaning, it physically removes oral biofilm and food residues through the physical perspective of the oral airbag cleaner. The brush head of TongueClear oral airbag cleaner is made of maternal and infant food-grade silicone material, 3D airbag design, and Flexconfcorm adaptive fitting technology, which can fit the intricate internal space of the mouth. It is soft enough and flexible, and it is not easy to damage the delicate oral mucosa. The patented one-piece scraping texture design can massage the gums while physically erasing oral biofilm and food residues, promote blood circulation in the periodontal area, improve Yaying's resistance, reduce the discomfort caused by oral inflammation, reduce the degree of gum atrophy, and improve gum tissue metabolism Most oral problems are related to oral hygiene. The eutrophic oral cavity and its moist and warm environment will lead to the proliferation of harmful bacteria in the oral cavity. The stubborn bacterial biofilm cannot be scientifically suppressed. Large-area biofilm will cause oral inflammation and further threaten oral health. Common cleaning methods in the market have the disadvantages of strong dependence, strong cleaning limitations, and poor results. TongueClear takes oral mucosal cleaning as the starting point and takes science, safety, and sustainability as the product development direction. Scientific oral sterilization helps us prevent oral diseases. TongueClear uses physical and biological means to better remove harmful pathogenic bacteria in the oral cavity to protect the oral cavity. Gum recession should not be underestimated, and the initial gum bleeding caused by recession should not be underestimated. If you ignore it, it will be too late when the teeth fall out.

With the development of the times and the improvement of quality of life, people are paying more and more attention to oral problems. However, oral problems are increasing exponentially year by year and are becoming younger. As a developed country, the United States pays much more attention to oral care than other countries. In 2020, 74% of its adults went to the dentist. Oral problems are ultimately due to poor oral environment. Take the young people of Generation Z as an example. They have diverse lifestyles, but their oral problems are more serious. Some even need to have their teeth filled or implanted. Generation Z has a deeper and more scientific understanding of oral problems and spends a lot of time on dental cleaning and care. Why do oral problems still occur frequently? Obviously, a lot of time is spent on care, but it is still unavoidable. Is it due to inadequate brushing, or are there factors that are ignored? In anatomy, 75% of the tissues in the oral are covered by oral mucosa. However, in the general public's perception, the key to oral problems is only focused on teeth. Although teeth are in direct contact with food and are frequently used, they only occupy 25% of the oral. Therefore, the key to cleaning the mouth is not just cleaning the teeth, but cleaning the mucosa is more important, and mucosa cleaning cannot but mention the culprit of all oral problems - oral biofilm. Oral biofilms are commonly found attached to the oral mucosa and various parts of the oral cavity. They are formed by the interaction of multiple bacterial communities, including various pathogenic oral bacteria such as caries bacteria and dental plaque bacteria. With the intake and residue of food, nutrients are provided to the oral flora. If they are not cleaned in time, they will rely on nutrients to replicate and multiply rapidly, causing oral diseases. Currently, common oral cleaning methods include brushing teeth, tongue brushes or mouthwashes. If you want to rely on existing products to achieve full oral cleaning, it is difficult and the related products have strong limitations, and it is not possible to achieve deep cleaning of the entire mouth. The residual biofilm in the mouth can achieve full oral coverage in just 12 hours, which is one of the fundamental reasons for the recurrence of oral problems. In terms of cognitive misunderstandings about oral cleaning, people generally understand oral cleaning as brushing teeth, but the key to oral hygiene is closely related to the oral mucosa. Common oral mucosa cleaning products on the market are basically concentrated in toothbrushes, tongue brushes and mouthwashes. Toothbrushes can only simply remove biofilms attached to teeth, and it is difficult to destroy biofilms attached to oral mucosa, and toothbrush bristles can easily damage the delicate oral mucosa. Tongue brushes are low in price, but the material is mostly hard, and the scene of use is single. It can only be used on tongue coating. The hard material lacks softness and fit, which can easily cause damage to the mucosa and poor comfort, making it difficult to form a habit of persistent use. Common mouthwashes on the market are mostly chemical reagents, designed to inactivate bacteria in the mouth, but mouthwashes can only kill bacteria on the surface of biofilms and cannot achieve deep cleaning. At the same time, chemical reagents will kill all bacteria in the oral, which will cause disorder of bacterial flora in the oral and reduce the self-cleaning ability and resistance of the oral. Considering the current situation and needs of the general public regarding oral mucosa, Tongueclear combines oral mucosa with the characteristics of the oral cavity of different age groups, and based on the principle of long-term use without side effects, has developed a variety of oral airbag brushes, oral mucosa gel, oral cleaning finger wipes and other products with physical and biological cleaning capabilities. The oral airbag brush is made of maternal and infant food grade liquid silicone. It has a patented brush head that integrates an airbag and a scraper. With the support of flexconforn adaptive fitting technology, it fits tightly to the inner wall of the oral cavity to reduce the foreign body sensation, and its soft nature does not hurt the delicate oral mucosa. Unlike other cleaning methods, Tongueclear uses gentle scraping to perform deep physical cleaning of the tongue surface, gums and other areas covered by the oral mucosa, effectively destroying the biofilm and removing residues. After cleaning with an oral airbag brush, use oral mucosa gel to slow down the formation of oral biofilm. Oral mucosa gel uses biological enzymatic hydrolysis technology to dissolve harmful bacteria in the mouth with the help of lysozyme, effectively reducing bacterial growth. At the same time, Oral mucosa gel contains glycosidase, which can decompose residual sugar in food in the mouth, cut off the source of nutrients for bacteria, and slow down their regeneration. Through the above methods, on the basis of physically destroying the biofilm, the microscopic biological enzymatic hydrolysis technology is used to reduce the activity of bacteria in the mouth, slow down the formation of biofilm, and thus protect the oral cavity. The root cause of potential oral crises lies in oral hygiene problems. Only by deeply understanding the causes, processes and results of the lesions can we accurately "prescribe the right medicine" and achieve early detection and early prevention. From the analysis of actual cases, we can see that the biofilm in the mouth is one of the key factors for us to prevent potential oral diseases. Long-term use of oral airbag brushes and oral mucosa gel products using bio-enzymatic hydrolysis technology will greatly improve the condition of oral biofilms, thereby effectively protecting our oral health.

Definition And Causes Periodontitis is a common oral disease. It is the product of early stage gingivitis that is not treated in time. If periodontitis is not treated in time, it will directly cause tooth loss. The main cause of periodontitis is that dental plaque in the mouth is not cleaned in time, and it accumulates for a long time to form dental calculus. Dental calculus irritates the gums, causing gingivitis, and then develops into periodontitis. At present, the main symptoms of periodontitis include bleeding gums, redness and swelling, gum atrophy, loose teeth, and bad breath. Treatment Of Periodontitis The key to treating periodontitis is to control inflammation and remove dental plaque. The following are common treatments for periodontitis: Professional cleaning: Deep cleaning of teeth by dental professionals, including supragingival scaling and subgingival scaling, to remove plaque and tartar on the surface of teeth and under the gums. Drug treatment: On the basis of cleaning, the doctor may prescribe antibiotics or anti-inflammatory drugs to control infection. Surgical treatment: For patients with severe periodontitis, surgery may be required to remove damaged tissue or rebuild periodontal structure. Oral care products: All of the above treatments may cause gingival injury and mucosal wounds. It should be noted that 75% of the entire mouth is covered by mucosa. Therefore, if you want to achieve true full-mouth cleaning, you must pay special attention to oral mucosal cleaning. In oral cleaning, in addition to the normal use of toothbrushes and dental floss, you can try to use oral mucosal cleaning products, because the formation of dental plaque is due to the failure to remove oral bacterial biofilm in time. Over time, plaque accumulation will form tartar, which will stimulate the gums and cause a series of gum problems. It is recommended to use Tongueclear oral mucosa cleaning products, such as oral airbag cleaners, oral cleaning finger wipes and oral cleaning gels. You can effectively clean the oral mucosa according to your needs, reduce plaque accumulation, and help control the recurrence of periodontitis. Preventive Measures For Periodontitis Prevention of periodontitis is more important than treatment, and the focus of prevention is to develop and maintain good oral hygiene habits and have regular dental checkups. Here are some preventive measures for reference: Proper oral care: It is recommended to brush your teeth with a soft-bristled toothbrush every morning and evening to ensure that the surface of the teeth and the area around the gum line are cleaned. At the same time, using Tongueclear's oral airbag cleaner can clean other parts other than teeth, such as under the tongue, tongue, upper and lower jaws, inside the cheeks, etc., to clean oral bacterial biofilm in all directions without dead ends, prevent the formation of dental plaque, and prevent oral diseases. Use dental floss: Use dental floss to clean the gaps between teeth every day, and promptly remove food residues and dental plaque that are difficult to clean with a toothbrush. Dietary adjustment: Reduce sugar intake to avoid providing too much nutrients to oral bacteria. At the same time, consuming more foods rich in vitamin C and calcium will help enhance the health of gums and teeth. Regular dental checkups: Have a dental checkup at least twice a year to detect and treat oral problems in a timely manner and prevent the occurrence and deterioration of periodontitis. Conclusion Periodontitis is a serious but preventable oral disease. Through proper oral hygiene habits, regular professional examinations and the use of professional products such as Tongueclear for oral mucosal cleaning, the occurrence of periodontitis can be effectively prevented and controlled. Tongueclear's products not only fill the gap in the market, but also bring significant progress to comprehensive oral health.

Gingivitis is a common gum disease and the early stage of periodontal disease. It can cause irritation, redness, swelling, and bleeding of the gums (the tissue surrounding the base of the teeth), and if left untreated, it can progress to periodontitis and tooth loss. According to the World Health Organization's 2022 Global Oral Health Status Report, 3.5 billion people worldwide suffer from oral diseases, with gingivitis being one of the most common. This has become a global issue and can lead to serious health complications. In this blog, we will explore the causes of gingivitis, its real dangers, and why prevention should take precedence over treatment. Causes of Gingivitis Gingivitis can be categorized into two types: plaque-induced and non-plaque-induced. Currently, nearly all cases of gingivitis are caused by plaque. The most common cause is poor dental and gum care, which leads to the buildup of dental plaque on the tooth surface. If plaque is not promptly removed, it hardens into tartar. The accumulation of bacteria in tartar makes plaque even more difficult to remove, further irritating the gums. The longer plaque and tartar remain on the teeth, the greater the irritation to the gums, leading to swelling and bleeding over time, ultimately causing gingivitis. Dangers of Gingivitis Though gingivitis is a common and mild oral disease, if left untreated, it can spread to deeper tissues and bones, becoming more severe periodontitis, which may lead to tooth loss. It can also introduce new health risks, including cognitive decline and dementia. Bei Wu, Dean and Professor of Global Health at New York University's Rory Meyers College of Nursing, discovered a correlation: the more teeth you lose, the greater the risk of cognitive decline and dementia. In one of the largest studies of its kind, Wu analyzed the health data of 34,000 patients in the U.S. and found that for every tooth lost, the risk of cognitive impairment increased by 1.4%, and the risk of dementia increased by 1.1%. Overall, compared to those with intact teeth, individuals who lost teeth had a 48% higher risk of cognitive impairment and a 28% higher risk of dementia. Preventive Measures for Gingivitis 1.Daily Oral Care: Brush your teeth at least twice a day for 2 minutes each time, and use dental floss at least once a day. Flossing helps remove plaque, the main cause of gingivitis. 2.Comprehensive Oral Cleaning: In addition to cleaning the teeth and gums, the entire oral cavity should be cleaned. Use products like oral airbag cleaner or oral finger wipes that are gentle on the oral mucosal to scientifically remove bacterial biofilm and maintain a healthy oral environment, better preventing oral diseases. 3.Healthy Diet and Lifestyle Habits: A balanced diet rich in vitamins and minerals promotes gum health. Avoid excessive sugar intake, as sugar leads to plaque buildup. Smokers should also quit, as smoking weakens the immune system, making it harder to fight off gum infections. 4.Regular Dental Check-ups: Professional cleanings and check-ups every 6 to 12 months can help detect early signs of gum disease and allow for timely prevention and treatment. Gingivitis may have minimal impact on your life and health initially, but the serious health issues it can lead to should not be overlooked. By taking preventive measures early, you can protect your oral health and overall well-being. 

What are oral bacteria? Oral bacteria are microorganisms that live in the oral environment. The human oral cavity is a complex ecosystem that contains hundreds of species of bacteria. Bacteria are divided into harmful bacteria and beneficial bacteria. Beneficial bacteria are beneficial to the human body and will not cause harm to the human body, but harmful bacteria may cause certain oral diseases, such as caries, periodontitis and gingivitis. Characteristics of oral bacteria Diversity: There are more than 700 types of bacteria in the mouth, mainly concentrated on teeth, gums, tongue and oral mucosa, and the types of bacteria distributed in each part are different. For example, anaerobic bacteria that cause bad breath like to be distributed in the tongue.Adaptability: The oral environment is complex and very suitable for bacterial growth. Bacteria absorb nutrients through food residues from the outside and reproduce wantonly.Biofilm: Oral bacteria will eventually form bacterial biofilms, which are usually attached to teeth and other oral surfaces in the form of bacterial biofilms. This biofilm will quickly become dental plaque, which is the main cause of caries and gingivitis. How to remove bacteria in the mouth? 1. Brush your teeth regularlyUse a soft-bristled toothbrush and fluoride toothpaste to brush your teeth twice a day, morning and evening, for two minutes each time. The purpose is to remove as much food residue and bacteria as possible from the surface of the teeth, especially biofilm and even dental plaque. When brushing your teeth, please use the correct brushing technique, hold the toothbrush at a 45-degree angle to the gums, and brush gently. Do not use too much force to avoid damaging the gums.2. Use dental flossIn addition to brushing your teeth, it is also important to remove food residue and bacteria between teeth and on the edge of the gums. Proper cleaning every day can prevent gingivitis and caries.The traditional cleaning tool is dental floss. When using it, you can take an appropriate amount of dental floss, gently insert it into the gap between teeth, and then slide it along the surface of the teeth to remove food residue and dental plaque. You can also choose waxed wire, unwaxed wire or dental floss stick according to your personal preferences and needs.3. Healthy dietDiet has an important impact on oral health. Maintaining a healthy diet can effectively prevent tooth and gum diseases.  Reduce sugar intake: Sugar is the main cause of tooth decay. Try to reduce the intake of sweets and carbonated drinks. Eat more fiber-rich foods: such as vegetables, fruits, etc. These foods can stimulate saliva secretion and help clean the mouth. Take enough calcium and vitamin D: It helps maintain the health of teeth and bones. Dairy products, nuts, and green leafy vegetables are good sources of calcium. 4. Regular oral examinationsRegular oral examinations and cleanings can detect and treat oral problems in a timely manner and prevent the occurrence of serious oral diseases. Examination frequency: It is recommended to have an oral examination at least twice a year. Depending on the individual's oral health, the dentist may recommend more frequent examinations. Professional cleaning: Dentists use professional tools for cleaning, which can effectively remove plaque and tartar, which cannot be completely removed by home care. 5. Maintain good habits Don’t smoke: Smoking not only causes bad breath, but also increases the risk of gum disease and oral cancer. Drink more water: Keep your mouth moist, saliva can help remove food debris and neutralize oral acid. Correctly cleaning the bacteria in the mouth and removing bacteria and food residue in the mouth can not only significantly improve breath and increase self-confidence, but also effective bacteria removal can significantly reduce the occurrence of oral problems caused by oral bacteria, such as dental caries and gingivitis. efficiency, effectively reducing the cost and time of dental visits, reducing the risk of heart disease, diabetes and other diseases, thus improving overall health. So start cleaning the bacteria in your mouth correctly from now on, giving you and your family a cleaner oral environment and staying away from oral diseases.

Oral health is an important part of physical health. Oral health is related to many factors, among which the impact of oral biofilm on oral health is the most easily overlooked by humans. Biofilm is a complex aggregate of microorganisms attached to the surface of the mouth and is also the main factor causing various oral health problems. Understanding the impact of biofilm on oral health and learning how to manage it is essential to prevent serious oral diseases. What is oral biofilm? Oral biofilm is a sticky, colorless film of bacteria that forms on teeth and other surfaces in the mouth. Biofilm begins to form within minutes of cleaning your teeth, and if not removed regularly, it gradually thickens and forms a hard, hard plaque. Biofilm provides a breeding ground for bacteria, which can lead to a variety of oral health problems. Common oral diseases associated with biofilm 1. Gingivitis: Gingivitis is an inflammation of the gums caused by biofilm accumulation. Early symptoms include red and swollen gums that may bleed when brushing or flossing. If left untreated, gingivitis may progress to more serious gum disease.2. Periodontitis: This is an advanced form of gum disease that affects the supporting tissues and bones of the teeth. If not managed correctly, periodontitis may lead to tooth loss. Bacteria in biofilms produce toxins that damage gums and bones, exacerbating the condition.3. Caries: Bacteria in biofilms produce acids that corrode tooth enamel, leading to tooth decay. If left untreated, tooth decay may cause pain, infection, and even tooth loss.4. Bad breath: Bacteria in biofilms produce volatile sulfide compounds (VSCs), which cause bad breath. Persistent bad breath is often a sign of biofilm accumulation. How to Manage and Prevent Biofilm-Related Diseases Daily Oral Hygiene Clean teeth: Brush your teeth at least twice a day using the Bass method, using fluoride toothpaste and a soft-bristled toothbrush to avoid damaging the gums. Clean between teeth: Use dental floss to remove food debris and biofilm between teeth and under the gums every day, or use Tongueclear oral finger cleaning wipes to manually remove bacterial biofilm and food debris from the teeth, gums, tongue and other parts of the mouth. Full oral cleaning: Use Tongueclear oral mucosa gel to reduce biofilm and bacteria in the mouth. (Long-term use of traditional mouthwash will disrupt the balance of oral flora) Professional dental care Regular Checkups: See your dentist regularly for checkups and professional cleanings. Your dentist can remove hardened tartar that can’t be removed by brushing and flossing. Scaling and root planing: For advanced biofilm-related disease, your dentist may recommend scaling and root planing to clean the roots of your teeth and remove biofilm beneath the gums. Lifestyle changes Diet: Reduce your intake of sugary foods and drinks, as sugars promote the growth of bacteria in biofilms. Stay hydrated: Drink plenty of water to help flush away food particles and bacteria. Avoid tobacco: Smoking and chewing tobacco increases the risk of biofilm-related diseases and other oral health problems. Oral diseases associated with biofilms pose a significant threat to dental health. By understanding the role of biofilms and practicing effective oral hygiene, you can prevent these diseases and maintain a healthy mouth. A combination of regular dental exams and routine care is essential to managing biofilms and ensuring a healthy mouth. Take action now to protect your smile and your overall health.

Relevant data show that oral hygiene affects the overall health of the body. If oral bacteria are not removed in time, they will enter the human body and affect human health. For example, periodontal bacteria and other substances may enter the blood circulation, causing blood hypercoagulation and increasing the risk of thrombosis. Periodontitis increases the risk of COPD. Periodontal disease may aggravate digestive tract diseases by destroying the intestinal epithelial barrier and changing the intestinal flora, so maintaining good oral hygiene is essential for overall health. The following is some basic oral hygiene information to help you maintain oral health. First, make sure you brush your teeth twice a day. Use fluoride toothpaste and a soft-bristled toothbrush, and brush for at least two minutes each time. When brushing, make sure to clean all tooth surfaces, including the back teeth. At the same time, it is also important to use the correct brushing technique: hold the toothbrush at a 45-degree angle to the gums and gently make circular motions instead of brushing hard. But true oral hygiene is not just about cleaning teeth. We also need to clean the gums, tongue coating, upper and lower jaws, and under the tongue. We need to truly achieve all-round oral hygiene. Secondly, clean the gaps between teeth every day to effectively remove food residues and dental plaque. You can use traditional dental floss here, but you need to be gentle when using it and don't hurt your gums. Or you can choose to use Tongueclear's latest oral cleaning finger wipes. This product adopts a finger buckle design, which is very convenient. The material is 100% medical grade material, 0 alcohol, and no harmful substances are added. You can clean the oral area according to your needs, including but not limited to the gaps between teeth. Dietary habits also have a direct impact on oral health. Avoid excessive intake of sugary foods and drinks, which can easily lead to tooth decay. Instead, eat more fiber-rich fruits and vegetables, as well as foods rich in calcium and phosphorus, such as dairy products and nuts, which can help strengthen teeth.Regular dental checkups are another key factor. It is recommended to visit the dentist every six months for a comprehensive checkup and cleaning. The dentist can detect and treat potential oral problems in a timely manner, preventing the occurrence and development of diseases. In addition, quitting smoking and reducing alcohol consumption also have a significant impact on oral health. Smoking and excessive drinking not only cause tooth discoloration, but also increase the risk of oral cancer and gum disease. To maintain oral health, it is best to quit smoking completely and limit the amount of alcohol you drink.Finally, don't ignore the choice of oral health products. Choose the right oral care products for you and achieve true oral hygiene. Start taking care of your mouth today! A healthy mouth can not only give you a bright smile, but also improve the quality of life.

Parenting for new parents is not easy, sometimes it takes a lot of effort, no effect, but make the baby cry and make trouble, simply worry broken heart.  Here are 10 new parents easy to make mistakes. Mistake 1: Always outdress an adult In fact, the newborn's ability to regulate its own temperature is not strong as adults, and the body's self-cooling function is not perfect, so it is better to wear less, but also do not wear more. The standard is: how much mom and dad wear, how much to the baby wear, would rather wear less, do not wear more. Medical history is littered with deaths from overheated newborns, but it seems unheardof an accident caused by underdressing. Mistake 2: Sharing a bed with your mother is easy to take care of Many Chinese mothers like to share a bed with their newborns for two reasons: 1. They think it's easier to take care of them at night. 2. I think it is inhumane for a baby to leave his mother's arms when he is just born. In fact, the newborn and mother share the bed but a lot of danger, because the children's awareness of independent activity is relatively weak, in case the mother fell asleep when breastfeeding, it is easy to cause the newborn breathing and suffocation; In addition, the new mother is generally exhausted, sleep at night may sleep more heavily, a turn is not careful, there may be a risk of pressure on the child. Mistake 3: Sleeping with a quilt and pillow Many mothers will feel that the newborn should be like themselves, sleep is to cover the quilt and pillow pillow, who knows, this is also a lot of danger. It is possible to be careless, or a child's arm, a kick, the quilt may cover the child's mouth and nose, blocking breathing and thus dangerous. Cover the quilt and pillow pillow, as well as with the same risk, the newborn's physical structure or different from adult ones and should, before two years of age, they lie on your back, the body and head is in a horizontal line (and adult is the head lower than the body), as if with a pillow, so head will be higher than the body, no matter how thin, how low pillow, Will bring certain adverse effects on the development of newborn bones. Mistake 4: Having to wake up in the middle of the night to breastfeed Many newborns may need breast milk every two hours during the day, but at night may be continuous 5-6 hours, or even longer do not eat, therefore, many mothers worry that children sleep too long at night and hungry, will deliberately wake them up to breastfeed. In fact, this is very wrong, for anyone (including small babies), sleep at night is more important than eating, they can not eat, but they must sleep well at night, of course, the newborn jaundice children except. Mistake 5: The quieter your sleeping environment, the better While adults may need a quiet place to sleep or rest in order to truly relax, this doesn't work for babies. Infant sleep background environment is more noisy better, more noisy they sleep more sweet, in fact, it is not difficult to understand, mom and dad think about living in the mother's stomach for nine months, although the hearing system is in the later development of mature, but the children already accustomed to the mother's stomach blood flow, the heart beats, and all other noisy voice, leaving my mother's belly, Who would not adapt to suddenly being placed in a very quiet environment? So parents really don't have to tiptoe around and do whatever they need to do while their babies sleep, and it's great if there's some music in the background. Since childhood sleep does not need to be in a very quiet environment, but also more conducive to children's later sleep habits and sleep quality. Mistake 6: Not feeding breastfed babies as needed The guiding principle for breast milk should be feeding as needed. Every doctor will say that every two hours is the right time to breastfeed a newborn, but that is an average time, not a blanket time. For children who are breastfed exclusively, it should be feeding on demand and feeding when they are hungry. It is believed that many mothers have the experience of drinking breast milk for many times in a short period of time, and also have the experience of not needing breast milk for 3-4 hours. The frequency of breast milk completely depends on the children themselves. Mistake 7: Babies need to bathe every day Taking a bath every day may be a habit of many parents, but the doctor reminded that the baby is very clean, do not need to take a bath every day, even if the children born in summer, more or less during the day will sweat, but also do not need to take a bath every day, and the sweat can also play a nourishing role on the skin. Newborns would rather be dirty than dry skin from too much bathing. Your baby doesn't have to take a shower every day, and it doesn't have to be shower dew. Mistake 8: Babies are not allowed to go out before they are a month old Influenced by mothers' confinement, many mothers (especially the elderly) will think that the baby is not allowed to go out before the month is up. But in fact, two weeks after the baby is born, the mother can take the baby for a walk in the park around the home for half an hour a day. Such a walk out, not only conducive to the mother's postpartum recovery, but also more conducive to children breathing fresh air. Mistake 9: Crying is to be fed or hugged Many new parents would argue, is a cry like children and want to embrace the, the fact is not the case, for newborn babies, they still won't do anything, baby cry, may be hungry, also may be want to mother's arms, but more likely is that they are a method of "fun", a form of exercise myself, Or there are other needs (dirty diapers, hot and cold), so mothers must have the ability to judge the reason why children cry, a cry to hug or feed, is absolutely not. Mistake 10: A package that is too tight is not comfortable Parents own experience is, wearing tight clothes loose more than comfortable and at ease, but for newborn babies is on the contrary, think of mothers womb space, think again baby gathers the world enjoy the space, it is not hard to understand, for newborns, they wrapped too tight, the more feel safe and comfortable. If wrapped tightly like zongzi, children will sleep very steadfast, on the contrary, children not only frequently woke up, but also sleep very shallow.
