The Hidden Benefits of Tongue Scraping for Oral Health

The significance of an effective oral care routine can not be overstated. After all, poor oral hygiene contributes to dental health complications and systemic conditions such as diabetes. 

While brushing and flossing are effective at cleaning the teeth and interdental spaces, tongue scraping is a lesser-known oral care practice that deserves attention. 

This method, rooted in ancient oral care traditions, has gained recognition in modern dentistry for its potential health benefits in promoting oral hygiene. This article discusses the advantages of tongue scraping, its contribution to the broader aspects of oral health, and how to incorporate it into your daily oral care routine.  

Understanding Tongue Scraping

Tongue scraping is an oral hygiene practice that involves removing plaque and bacteria from the tongue’s surface using a dedicated scraping tool. The process involves placing the scraper at the back of the tongue and dragging it forward gently to remove accumulated residue from its surface. 

Tongue scraping can be traced back to Ayurvedic medicine which originated in India more than 3000 years ago. The goal of tongue scraping in Ayurveda is to improve digestion and overall health by removing the buildup of toxins, called ‘ama,’ from the tongue’s surface.  

Tongue-cleaning practices can be found in various other cultures, including Traditional Chinese Medicine, where the tongue can be used to assess a person’s health. In Japanese culture, tongue cleansing has been practiced for centuries as part of overall oral care. 

Enhanced Oral Hygiene

Tongue scraping is necessary for a comprehensive oral hygiene routine since bacteria, dead cells, and food debris can accumulate on the tongue’s surface. Here’s how tongue scraping can reduce the risk of gum disease and tooth cavities:

Reduction of Harmful Oral Bacteria

The tongue’s rough surface is an ideal breeding ground for bacteria associated with tooth cavities (Streptococcus mutans) and gum disease (Porphyromonas gingivalis). 

While brushing and flossing are effective at maintaining oral health, they mainly focus on cleaning the teeth and interdental spaces. Regular tongue scraping significantly reduces the amount of harmful bacteria in the mouth and reduces the risk of developing cavities or gum disease. 

Preventing Plaque Formation

Plaque, a sticky biofilm composed of oral bacteria and food debris, can contribute to cavity formation and gum disease if left unchecked. Incorporating tongue scraping into your oral care routine disrupts plaque buildup by removing oral bacteria that accelerate its formation from the tongue. 

Balancing Oral PH

Oral bacteria produce acids as the breakdown of sugars from consumed foods. These acids can corrode the enamel and create an ideal environment for plaque formation. Tongue scraping helps maintain a healthy pH balance in the mouth by removing harmful bacteria from the tongue. A healthy oral pH balance reduces the risk of acid-induced enamel erosion. 

Improving Saliva Production

Saliva plays a crucial role in oral health. Saliva neutralizes acids, washes away food debris, and remineralizes the teeth. A clean tongue can enhance saliva production and distribution throughout the mouth. The saliva maintains a healthy oral environment, reducing the risk of cavities and gum disease. 

Reducing Bacteria and Bad Breath

Incorporating tongue scraping into your oral care routine significantly reduces odor-causing agents from the tongue resulting in fresher breath and improved oral hygiene. Here’s how tongue scraping targets and reduces bad breath: 

Bacteria Removal

The leading cause of bad breath is the accumulation of bacteria on the tongue. When oral bacteria accumulate on the papillae, tiny bumps on the tongue’s surface, they metabolize leftover food particles, dead cells, and other impurities, producing foul-smelling compounds. Tongue scraping disrupts this process by eliminating these harmful bacteria from the tongue. 

Sulfur Compound Reduction

Oral bacteria produce volatile sulfur compounds (VSCs) as they metabolize food particles and other substances on the tongue. These compounds, predominantly hydrogen sulfide and dimethyl sulfide, have strong and foul odors that contribute to halitosis. Tongue scraping combats bad breath by removing bacteria and disrupting the formation of VSCs. 

Disruption of Biofilm

Oral biofilms, complex communities of microorganisms that adhere to oral surfaces, provide an ideal environment for harmful oral bacteria to accumulate and multiply. The tongue’s rough surface is ideal for biofilm formation. Its bumps and crevices provide spaces for bacteria to anchor and grow. 

Tongue cleansing by scraping dislodges bacteria from the tongue while fragmenting the biofilm structure. Additionally, regular tongue scraping prevents the biofilm from fully forming and enhances the effectiveness of other oral care practices, such as brushing and flossing

Enhanced Saliva Production

Saliva contains enzymes that can help neutralize the negative effects of odor-causing bacteria. For instance, saliva contains antimicrobial proteins like lactoferrin and lysozyme, which help reduce the population of bacteria responsible for bad breath. Tongue scraping stimulates the tongue’s nerve endings and triggers the salivary glands to produce and release saliva. 

Improved Digestive Health and Sense of Taste

A clean tongue plays a crucial role in enhancing the sense of taste and improving digestive health. Plaque formation on the tongue’s surface can limit the function of taste buds by blocking the direct contact between taste receptors and food particles. Consequently, this can contribute to dulled taste sensations and a reduced ability to distinguish between flavors. 

Regular tongue scraping removes plaque buildup and exposes taste receptors leading to a heightened sense of taste and a more pleasurable dining experience. 

Since the mouth serves as the initial stage for the digestive process, a clean tongue creates a conducive environment for food breakdown and absorption. Harmful bacteria present in tongue plaque can disrupt the delicate balance of digestive enzymes and oral microflora. This imbalance can hinder the digestive process and contribute to ineffective nutrient absorption and gastrointestinal discomfort. 

Maintaining a clean tongue through scraping promotes a healthy oral ecosystem by reducing the amount of harmful oral bacteria. 

Promoting Overall Well-being

Cleaning the tongue can significantly impact your self-confidence, oral health, and overall well-being. First, a coated tongue is unsightly and often indicative of poor oral health practices. Preventing plaque buildup through scraping can restore the tongue to its natural shade and promote an aesthetically pleasing oral appearance.

Moreover, systemic conditions such as cardiovascular diseases, respiratory infections, and diabetes have been linked to poor oral health. Incorporating tongue scraping into your oral care routine minimizes the potential for dental complications and significantly reduces the risk of developing debilitating systemic conditions.

How to Properly Use a Tongue Scraper


Choosing the Right Tongue Scraper

  • Material: Look for a tongue scraper made of stainless steel or copper. These materials are easy to clean, durable, and less likely to harbor bacteria compared to plastic ones
  • Design: Choose a scraper with a wide, curved cleaning surface. This shape allows for better coverage and more efficient removal of plaque 

Using the Tongue Scraper

  • Timing: It’s best to use the tongue scraper in the morning, just after you wake up. Bacteria can accumulate on your tongue overnight, leading to bad breath
  • Preparation: Before using the scraper, brush your teeth thoroughly. This will remove loose debris and create a cleaner environment for tongue scraping.
  • Positioning: Hold the tongue scraper with both hands, ensuring that the cleaning surface is facing downwards and the curved portion is placed at the back of your tongue

Scraping Technique

  • Extend your tongue out
  • Place the scraper on the back of your tongue, as far back as you can comfortably reach without triggering a gag reflex
  • Apply gentle pressure and slowly drag the scraper forward along the surface of your tongue. Avoid pressing too hard to prevent discomfort or injury
  • Rinse the scraper after each pass to remove collected debris

Repeat the scraping process 3-5 times, gradually moving toward the front of your tongue with each pass. After each pass, rinse the scraper under running water to remove the accumulated debris.

Tongue scraping is an effective oral care routine that removes plaque buildup from the tongue’s surface. This simple yet impactful habit combats bad breath and helps prevent cavities, gum diseases, and other oral complications. Beyond oral health, tongue scraping can improve digestion and enhance your sense of taste.
