Photo showing black, hairy tongue Black, hairy tongue

Black, hairy tongue is a temporary, harmless (benign) oral condition that gives your tongue a dark, furry appearance. The distinct look of black, hairy tongue usually results from an overgrowth of bacteria in the mouth.

Although black, hairy tongue may look alarming, it doesn't cause any health problems. Black, hairy tongue usually resolves without medical treatment.
