The History of Tongue Scraping

The practice of tongue scraping, also known as tongue cleaning or tongue brushing, has a long history that dates back thousands of years. It has been an integral part of oral hygiene in various cultures around the world. While the exact origins of tongue scraping are unclear, evidence suggests its presence in ancient civilizations and traditional medical systems.


Ancient Ayurvedic and Traditional Chinese Medicine (TCM) texts provide some of the earliest documentation of tongue cleaning practices. In Ayurveda, an ancient Indian system of medicine, tongue scraping is mentioned as part of daily self-care routines known as Dinacharya. It is believed to remove toxins or "ama" from the body, contributing to overall health and well-being. Similarly, TCM views the tongue as a diagnostic tool for assessing an individual's health, and tongue scraping is used to remove excess debris and maintain balance.


In traditional Chinese culture, tongue cleaning has been practiced for centuries. Ancient texts, such as the Compendium of Materia Medica by Li Shizhen (16th century), describe various methods of tongue cleaning using tools made from different materials, such as gold, silver, jade, or ivory.


In European cultures, tongue cleaning has also been a part of oral hygiene practices. In the Middle Ages, tongue scraping was recommended by physicians and was mentioned in medical texts. The famous 17th-century diarist Samuel Pepys made reference to his own tongue scraping habits.


During the 20th century, as dental hygiene practices evolved, the focus shifted primarily to tooth brushing and flossing. However, tongue scraping regained attention in recent decades, with increased awareness of the importance of oral health and the role of the tongue in oral hygiene.


Today, tongue scrapers are readily available in various forms, including metal, plastic, and silicone, and are widely used by individuals seeking to improve their oral hygiene routines. These modern tongue scrapers are designed to gently remove bacteria, debris, and dead cells from the surface of the tongue.


While the traditional practice of tongue scraping focused mainly on maintaining oral hygiene and overall health, modern tongue scraping has gained popularity for its potential benefits in reducing bad breath, improving taste perception, and promoting fresher breath.


Pros of Tongue Scraping


  • Improved Oral Hygiene: One of the primary benefits of tongue scraping is its ability to enhance oral hygiene. The tongue harbors bacteria, food debris, dead cells, and other substances that can contribute to bad breath and oral health problems. Regular tongue scraping can effectively remove these accumulations, leading to fresher breath and a cleaner mouth.
  • Reduced Risk of Oral Infections: By removing bacteria and other microorganisms from the tongue's surface, tongue scraping can help reduce the risk of oral infections. Certain harmful bacteria can lead to conditions such as thrush or oral candidiasis. Tongue scraping, when combined with regular brushing and flossing, can play a valuable role in preventing such infections.
  • Enhanced Taste Perception: A coated tongue can hinder taste perception, making food taste less flavorful. By scraping the tongue and eliminating the accumulated debris, taste buds are exposed to flavors more effectively. Consequently, tongue scraping can enhance the overall taste experience, making meals more enjoyable.
  • Promotes Overall Health: Research suggests a potential link between oral health and overall well-being. Poor oral hygiene has been associated with various health issues, including cardiovascular disease, respiratory problems, and diabetes. Tongue scraping, as part of a comprehensive oral care routine, can contribute to better overall health and reduce the risk of certain systemic conditions.


Cons of Tongue Scraping


  • Discomfort or Sensitivity: Some individuals may find tongue scraping uncomfortable or experience sensitivity. The scraping motion can cause temporary irritation, especially if done forcefully or with excessive pressure. It is important to use a gentle approach and adjust the pressure according to personal comfort levels.
  • Risk of Injury: Care must be taken while using a tongue scraper to avoid any potential injury. A rough or improperly used scraper can lead to tongue abrasions or lacerations. It is crucial to choose a soft, flexible scraper with smooth edges to minimize the risk of injury.
  • Psychological Discomfort: For individuals who are new to tongue scraping, the practice may induce a gag reflex or a feeling of discomfort. This can be attributed to the sensation of scraping the tongue's surface. However, with regular use and proper technique, most people adapt and find this discomfort diminishes over time.
  • Limited Scientific Evidence: While there are anecdotal reports on the benefits of tongue scraping, scientific research on its effectiveness is relatively limited. Further studies are needed to establish conclusive evidence regarding the impact of tongue scraping on oral health and overall well-being.


Tongue scraping offers several potential benefits for oral health, including improved oral hygiene, reduced risk of infections, enhanced taste perception, and promotion of overall well-being. However, it is important to be mindful of potential drawbacks such as discomfort, the risk of injury, and limited scientific evidence. As with any oral hygiene practice, tongue scraping should be approached with care and individual considerations. Consulting a dental professional can provide personalized guidance on incorporating tongue scraping into a comprehensive oral care routine.
