Very good tool/tongue cleaner. I consider it a very important step in the care and cleanliness of the tongue as clinical studies have shown that microbial factors on the surface of the tongue are the main cause of bad breath and cleaning-scraping the tongue is the most effective way to reduce bad breath. It has a triangular-shaped head that helps clean the back of the tongue, a triple scraper that makes the removal of microbial factors on the surface of the tongue more effective, raised scrapers for cleaning the back of the tongue, and flat scrapers for cleaning the sides of the tongue.
