The last time you took a good look at your tongue was probably after eating a piece of colored hard candy or taking a photo with your tongue out à la 2013 Miley Cyrus. Tongues are kind of weird when you think hard about them; they're hunks of muscular flesh in the middle of your mouth. In traditional Chinese medicine, how your tongue looks is a pretty big deal, and some doctors say they can diagnose an issue just by looking at the patterns and colors on it. Medical doctors and dentists can also tell a lot about your health by looking at your mouth and tongue (they don't make you say "ah" for nothing). So, if you notice your tongue is a little white, what does that mean?

That's probably tongue plaque, says Fariba Younai, DDS, professor of clinical dentistry at UCLA School of Dentistry. Your tongue naturally cleans itself and renews the cells on the surface to get rid of bacteria, dead cells, and debris, Dr. Younai says. But when someone has tongue plaque, that renewal doesn't happen and your tongue gets covered in a white film.
