Your tongue is unique to you, and you may be surprised to know that you can tell a lot about your health by looking at it. 

Head to the mirror and stick your tongue out. If you’re healthy, your tongue should be an even pink color and you should be able to see tiny bumps over the surface. These bumps are called papillae. There are four different types of papillae on the tongue.

Filiform papillae: This type covers most of the front of your tongue. Unlike the other papillae, they do not contain taste buds, but give your tongue its slightly abrasive surface.

Fungiform papillae: Found on the upper surface, the tip and sides of your tongue, these papillae have the ability to discern five tastes: bitter, sweet, sour, salty and umami.

Foliate papillae: These are found on the sides of your tongue in short vertical folds. They contain many taste buds.

Circumvallate papillae: Found at the back of your tongue, circumvallate papillae also contain taste buds.

What Your Tongue Reveals About Your Health

Your tongue is made up of a group of muscles, which you use all the time for speaking, eating, and swallowing. If you are having a problem with it, it can be very uncomfortable. Your dentist can tell a lot about your health by the condition of your tongue, from whether you drink a lot of soda to whether you have an eating disorder.
