Tongue Scraping: What to Know

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Tongue scraping is a practice that involves using a tool to clean the surface of the tongue. This method is often recommended as part of oral hygiene routines to help reduce bad breath and improve overall oral health. Here, we explore the efficacy and benefits of tongue scraping based on recent research findings.

Efficacy in Reducing Halitosis

Halitosis, commonly known as bad breath, is often caused by the accumulation of bacteria and volatile sulfur compounds (VSCs) on the tongue. A study investigated the combined effect of zinc lactate mouthwash and tongue scraping on intra-oral halitosis. The study involved 60 volunteers who followed two different oral hygiene protocols: one with just tooth brushing and another with additional mouth rinsing using zinc lactate and tongue scraping. The results showed that the protocol including zinc lactate mouthwash and tongue scraping significantly reduced both organoleptic scores (subjective breath odor assessment) and VSC concentrations compared to tooth brushing alone (p < 0.05)1.

Mechanism of Action

Tongue scraping works by physically removing the layer of debris, bacteria, and dead cells that accumulate on the tongue’s surface. This layer is a primary source of VSCs, which are responsible for bad breath. By reducing the bacterial load and the presence of these compounds, tongue scraping helps in maintaining fresher breath and potentially improving taste sensation.

Benefits Beyond Halitosis

While the primary benefit of tongue scraping is the reduction of bad breath, it may also contribute to overall oral health. By removing bacteria and debris, tongue scraping can help prevent dental issues such as plaque buildup and gum disease. Additionally, some users report an enhanced sense of taste after regular tongue scraping, as the removal of the coating on the tongue can make taste buds more sensitive.

Practical Considerations

• Frequency: For optimal results, tongue scraping should be performed daily, preferably in the morning as part of the regular oral hygiene routine.
• Technique: Use a tongue scraper made of metal or plastic. Gently scrape from the back of the tongue to the front, rinsing the scraper between strokes.
• Combination with Other Practices: Combining tongue scraping with other oral hygiene practices, such as brushing, flossing, and using mouthwash, can enhance its effectiveness in maintaining oral health.

Conclusion

Tongue scraping is a simple yet effective practice to reduce bad breath and improve oral hygiene. When combined with other oral care routines, such as the use of zinc lactate mouthwash, it can significantly reduce the presence of volatile sulfur compounds and improve breath odor. Regular tongue scraping can also contribute to overall oral health and enhance taste sensation1.
