There are several hundreds of small bumps called papillae, also known as taste buds, on the surface of a tongue. Usually, these papillae are not noticeable, but sometimes they could enlarge due to one reason or the other. If you notice the development of bumps on the back of your tongue, you should consult your doctor immediately to control it before they start affecting your normal life.

What Are Tongue Bumps?

Enlarged papillae, mostly a short-term nuisance, can make your eating, swallowing, and talking painful.  There are four types of papillae, namely filiform, fungiform, foliate, and circumvallate. Filiform papillae cover 2/3rd of the tongue and are responsible for the sense of touch. Foliate papillae line the side of the tongue and fungiform papillae help in differentiating temperature and flavor. Inflamed circumvallate papillae, located towards the throat positioned in a V-shape on the back of your tongue, usually heal automatically. However, spreading long-lasting bumps on the back of the tongue could be a sign of underlying disease. If you notice bumps on the back of your tongue, you should consult your doctor to seek a remedy.
