When to see a doctor

By Mayo Clinic Staff

Unless caused by a serious condition, white tongue generally will not harm you. Gently brushing your tongue with a toothbrush or tongue scraper and drinking plenty of water can help.

Make an appointment with your medical or dental health professional if:

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