@joycethedentist: Episode 2 | Bumps on the tongue are totally normal! The bumps are called papillae, and there are 4 different kinds: fungiform, circumvallate, foliate, and filliform. Besides filiform, they help to differentiate between salty, sweet, sour, bitter and umami flavors. Gently tongue scraping is a good way to clean oral debris and bacteria accumulating between the papillae. Tongue scraping can be done 2 times a day, and make sure to be gentle because rough tongue scraping can damage tastebuds. #tongue #papillae #hairytongue #tonguescraping
