What Would Make Your Tongue Turn Black?

Black, hairy tongue refers to a harmless medical condition characterized by a dark, furry growth on the tongue. An overgrowth of bacteria usually causes black, hairy tongue, according to the Mayo Clinic. A variety of factors can cause bacterial overgrowth.

Features

Black, hairy tongue occurs when papillae, small projections on the tongue, grow longer instead of shedding. Elongated papillae give the tongue a furry appearance. Bacteria and debris then accumulate on the papillae, turning the tongue black, brown or yellow.

Medications

Antibiotics can cause black, hairy tongue, since they affect the healthy bacteria in the mouth. Medicines that include bismuth, including Pepto-Bismol, may also cause it as well as mouthwashes and astringents.

Other Causes

Poor oral hygiene, breathing through your mouth and tobacco use can also cause black, hairy tongue, according to the Mayo Clinic.

Treatment

Practice good oral hygiene if you have black, hairy tongue. In addition, reduce tobacco use. Talk to your doctor before stopping prescription medications or if black, hairy tongue does not go away. Antibiotics may sometimes be necessary to treat this condition, according to Medline Plus.
