From ancient wisdom to modern science: The story of full-mouth cleaning

Introduction:

Our oral health depends not only on our teeth; the tongue, gums, and oral mucosa also play crucial roles.

Since ancient times, humans have recognized the connection between oral soft tissues and overall health, and have explored how to maintain the cleanliness of the entire oral cavity.

Modern scientific research has found that uncleaned oral mucosa is a breeding ground for bacterial biofilms, which are linked to halitosis, gingivitis, and even overall health.

In this issue, we will review the history of oral mucosal cleaning and reveal why comprehensive oral cleaning is becoming a new trend in modern oral care.

From Ancient Times to the Present: How Humans Protect Oral Soft Tissues

Phase 1 | The Ayurvedic Cleansing Phase (1500 BCE – 200 BCE, Ancient India)

In the ancient Indian Vedic medical system, oral hygiene was systematically documented.

The literature explicitly mentions practices such as tongue scraping (Jihwa Nirlekhana) and oil rinsing (Kavala/Gandusha) to remove deposits from the tongue, stimulate saliva production, and maintain bodily balance.

This stage was characterized by: direct contact with the tongue and oral mucosa; integration of oral hygiene into overall health management; and an emphasis on balance and long-term maintenance. This is the earliest traceable, systematic oral mucosal cleaning system with written records.

Phase 2 | Direct Contact Cleaning Phase (5th century BC – 1st century AD, ancient Greece and Rome)

In ancient Greece and Rome, the tongue and oral mucosa were considered important windows into one's health. Oral cleaning was often done by directly wiping the tongue and gums with fingers or linen/wool cloths dipped in salt water to remove mucous membrane coatings and odors.

People judged digestion and overall health by the color, thickness, and moisture of the tongue coating.

Oral mucosal cleaning at this stage had both practical nursing and early medical significance.

Phase 3 | Tongue Scraping Phase (5th-15th centuries, Medieval Europe)

In medieval Europe, people began using metal, bone, or wooden tongue scrapers to clean their tongues, focusing on removing the coating from the middle and back of the tongue.

This cleaning was mostly done in the morning, and more frequently when feeling unwell or experiencing bad breath.

People believed that tongue coating was an external manifestation of "decaying matter" from the body, and scraping it off helped improve breath and eliminate stagnation.

At this time, oral mucosal cleaning gradually became more tool-based and routine, but its core focus remained on health observation.

Phase 4 | Plant-Based Contact Oral Cleaning (3000 BC – Present, Arab and North African Regions)

In the Arab and North African regions, people have long used Miswak twigs to clean their mouths.

Through chewing and rubbing, the plant fibers come into contact with the teeth, gums, tongue, and oral mucosa, achieving a more comprehensive cleaning and stimulating saliva production.

Cleaning is often performed before and after meals and before religious ceremonies, emphasizing gentle yet frequent daily maintenance.

At this stage, people viewed teeth and soft tissues as an inseparable health system.

Phase 5 | Dental Center Cleaning Phase (19th century – mid-20th century, modern West)

From the 19th to the mid-20th century, oral hygiene in the West gradually focused on teeth.

People primarily brushed their teeth with toothbrushes and toothpaste, once or twice daily, with the goal of preventing cavities and maintaining dental health.

The tongue and oral soft tissues were almost entirely neglected, only receiving attention when there was pain or infection.

While tools improved during this period, the importance of comprehensive oral mucosal care was diminished, and awareness of long-term soft tissue maintenance declined.

Phase 6 | Gentle Mucosal Cleaning Under the Awareness of Biofilm (21st Century - Present)

In the 21st century, with in-depth research into oral microecology and biofilms, people have begun to pay attention to the gentle cleaning of the tongue, gums, and oral lining.

Use tongue scrapers and low-irritant cleaning products to clean daily or as needed, avoiding damage to the mucosa.

This stage emphasizes holistic oral health maintenance, treating teeth and soft tissues as a whole system, focusing on bacterial control and long-term health management, achieving comprehensive coverage from the center of the teeth to the entire oral mucosa.

The True Purpose of Oral Mucosa Cleaning

The core of oral mucosal cleaning lies in removing the biofilm covering the teeth, tongue, gums, and inner walls of the mouth. This thin, sticky bacterial aggregate is the source of many oral problems.

Cleaning the surface of the tongue removes bacteria and metabolic waste accumulated on the back of the tongue, reducing bad breath and a thick tongue coating; cleaning the gums and gingival sulcus reduces the occurrence of gingivitis and periodontitis, preventing bacteria from penetrating periodontal tissues; cleaning the oral mucosa reduces the chance of bacteria colonizing in all corners of the mouth.

③ Oral biofilms are not limited to the oral cavity; they are closely related to overall health. If bacteria from these biofilms enter the bloodstream, they can increase the risk of cardiovascular disease, diabetes, and chronic inflammatory diseases.

④ Maintaining thorough oral mucosal cleaning not only helps maintain the balance of the oral microecology, improves oral comfort and freshens breath, but also subtly protects overall health.

Scientific Insight: Why Cleaning Biofilms Is Crucial

The Challenges of Removing Oral Biofilm

Removing oral biofilm meets these five key requirements, but many cleaning methods fail to achieve them.

Comprehensive

Brushing your teeth only cleans the teeth, occasionally scraping the tongue with a tongue scraper, or rinsing your mouth with mouthwash only rinses the mouth, but bacteria still lurk in the hard-to-reach corners of the mouth.

Effective

Biofilms are formed by a large number of bacteria tightly adhering to each other through polysaccharides and proteins, making them difficult for ingredients in commonly used oral hygiene products to break down or loosen.

Safety

Brushing your teeth can cause gum bleeding, and a tongue scraper can easily scrape the tongue papillae with a little force, forcing you to be extremely careful for fear of hurting yourself.

Sustainability

Brushing teeth + rinsing mouth + scraping tongue is multi-step and complicated, making it easy to slack off when busy. "Is it really possible to stick to this every day?"

Without disrupting the balance of gut flora

Alcohol-based or strong antibacterial mouthwashes kill bacteria quickly, but also damage beneficial bacteria, leading to dry and unbalanced oral flora. "Is this kind of cleaning really healthy?"

Complete Oral Cleaning for Easy Health Protection:

To address this challenge, a combination of a specially designed oral brush for full mouth cleaning and a gentle gel toothpaste was developed.

01 Thorough Cleaning

The oral brush utilizes unique adaptive technology, achieving thorough cleaning of teeth, gums, jaw, tongue, and the inner walls of the mouth in a single application.

02 Decomposing Biofilm Structures

The gel toothpaste contains lysozyme, which reduces the adhesion of bacteria in biofilms, making it easy to remove biofilm when used with the oral brush.

03 Safety Protection

The oral brush's food-grade liquid silicone material and conformal pressure dispersion design, combined with the alcohol-free and SLS-free gentle formula of the gel toothpaste, ensure effective cleaning while avoiding mechanical damage and chemical irritation.

04 Sustainable Cleaning

Using the oral brush and gel simultaneously covers multiple cleaning areas, shortening the process, lowering the barrier to entry, and making it easier to maintain a cleanliness habit long-term.

05 Maintaining Oral Microbiome Balance

Primarily using physical removal, supplemented by gentle ingredients, and not relying on strong bactericides, it reduces odor-causing bacteria while maintaining a stable oral microecology.
