When to see a doctorBy Mayo Clinic staff
White tongue is generally harmless, and may be helped by brushing your tongue with a 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 two weeks
