Studies have shown that tongue scraping can remove 400 percent more bacteria and germs than brushing your tongue. Tongue scraping can help prevent gingivitis, tooth decay and reduce bad breath. You can buy tongue scrappers in the store. I have found the best ones are made by Discus Dental. You hold it with two hands forming a U shape and adapt it to the surface of your tongue. If you can’t find them, let us know and we can get them for you. They only cost about two dollars and are re-usable.
