When to see a doctor

By Mayo Clinic Staff

Medical treatment for yellow tongue usually isn't necessary. If tongue discoloration bothers you, try gently brushing your tongue with a solution that is 1 part hydrogen peroxide and 5 parts water once a day. Rinse your mouth with water afterward several times.

Quitting smoking and increasing fiber in your diet also may help by decreasing the bacteria in your mouth that cause yellow tongue and reducing the buildup of dead skin cells.

Schedule a doctor's visit if:

  • You're concerned about persistent discoloration of your tongue
  • Your skin or the whites of your eyes also appear yellow, as this may suggest jaundice
