Yellow tongue — a yellow discoloration of your tongue — is usually a temporary, harmless problem. Most often, yellow tongue is an early sign of a disorder known as black hairy tongue. Rarely, yellow tongue may be a sign of jaundice, a yellowing of the eyes and skin, which sometimes indicates liver or gallbladder problems.

Self-care is usually all that's needed to treat yellow tongue, unless it's related to another medical condition.
