Black hairy tongue is a condition that sounds frightening and also looks scary, but it is not life-threatening. This is caused by the significant amount of fungi or bacteria present in the mouth, making it look hairy and black. While long-term black hairy tongue may create disturbances, this condition is easily controlled with proper oral hygiene and changes in lifestyle.
The tongue contains thousands of tiny rounded projections, which are called papillae. The papillae, which are normally pinkish-white in color, are located on the surface and are shed off regularly. These papillae play a significant role as they are connected to the sensory nerves that manage a person’s sense of taste.
In rare cases, papillae do not shed off regularly and tend to grow up to fifteen times the normal size. As the papillae grow, food pigments, yeast, and bacteria get stuck. Black hairy tongue is caused by significant growth of yeast or bacteria trapped between these papillae. As the food pigments and buildup of plaque decompose, it results in dark pigmentation. This makes the tongue appear black and hairy.

What are the Symptoms of Black Hairy Tongue?

- Black discoloration of the surface of the tongue (the color may be brown, green, yellow, white, or tan)
