When to see a doctor

By Mayo Clinic Staff

White tongue is generally harmless, and may be helped by gently brushing your tongue with a toothbrush or tongue scraper and drinking plenty of water.

Make an appointment with your doctor or dentist if: 

  • You're concerned about changes in your tongue
  • Your tongue hurts
  • Your white tongue persists for longer than a few weeks
