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.
The most obvious sign of a black tongue is discoloration of the tissue on the tongue. Basically, this occurs when the papillae (small raised portions) of the tongue elongate for some reason and accumulate material. The collected matter in the tongue usually produces a dark appearance, but âblack tongueâ could also lead to a white, green, brown, or tan appearance, depending on the root cause. Your tissue may also take on a textured, âhairyâ feeling.
