What are the Benefits of Tongue Scraping? – Let’s Find Out

The tongue is one of the most unique parts of our mouth that functions in swallowing and speaking. When it comes to maintaining good oral hygiene, our primary focus always goes on the teeth and gums. However, it is essential to know that the tongue attracts the majority of the plaque and bacteria in the mouth. This is because of the papillary projections that trap the food debris and plaque and allow them to settle on the surface of the tongue.

Failure to clean the tongue increases the plaque buildup on the tongue surface, which is often reflected as a white coating. Routine tongue cleaning removes the unknown bacteria and plaque from the tongue surface and helps to get rid of bad breath. Tongue scrapers are specially designed oral health care tool which efficiently scrapes the plaque and provides a clean surface of the tongue.
