Black Hairy Tongue

Back

Black hairy tongue is a temporary, harmless oral condition that gives the tongue a dark, furry appearance. The distinct look usually results from a buildup of dead skin cells on the many tiny projections (papillae) on the surface of the tongue that contain taste buds.

SYMPTOMS

Symptoms include discolouration of the tongue, a furry or hairy appearance of the tongue, bad breath and a metallic taste in the mouth.

CAUSES

A black hairy tongue is caused by too much bacteria or yeast growth in the mouth. The bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections.
