1. Black hairy tongueBlack hairy tongue (in Latin, lingua villosa nigra) is the lengthening of papillae which are bumps on the surface of the tongue. Usually the ends of the papillae get rubbed away by food but sometimes they grow much longer than normal, making the tongue look furry. The extra tissue can get stained by food or tobacco and become yellowish brown or black. Even though it may appear alarming, black hairy tongue itself is harmless (although it is thought to be linked to the development of thrush).
