Black hairy tongue

Black hairy tongue occurs when bacteria or fungi is allowed to grow in the mouth, specifically on the tongue, that makes the tongue look black and hairy. The bacteria accumulate on small projections on the surface of the tongue called papillae. Under normal conditions these shed and go away. When they fail to shed, the papillae grow and lengthen, making them appear like hair on the tongue. Pigments from food or other bacteria get caught on the papillae. This causes them to appear black as they build-up. Some people report that their tongues turn brown, yellow and even green.
The frequency of the condition in children and young adults is around 8 percent. It can be as high as 57 percent in those addicted to drugs and incarcerated. There is around a 13 percent occurrence in the adult population. It has been reported more in men than women but both can suffer from the disorder.
