Black Hairy Tongue: Causes, Symptoms, Treatment, Home Remedies

What is Black Hairy Tongue?

Black hairy tongue is a disorder of the tongue, which is quite harmless and is a temporary oral condition. As the name itself suggests, the tongue takes on a furry/hairy black colored appearance. This distinctive look occurs as a result of accumulation of dead cells on the papillae. These papillae have multiple tiny projections on the tongue’s surface and they help with tasting of the food as they contain taste buds. There is accumulation of dead skin cells on the tongue which increases the length of the papillae. The longer papillae tend to trap the food we eat, or yeast, bacteria or get stained by food colorings, tobacco etc. This results in a black hairy appearance of the tongue. This kind of a black furry look on the tongue can be alarming to look at, however, it is quite harmless, painless and doesn’t cause any health problems and most of the times resolves without resorting to any medical treatment.
