Symptoms
By Mayo Clinic staffSigns and symptoms of geographic tongue may include:
- Smooth, red, irregularly shaped patches (lesions) on the top or side of your tongue
- Frequent changes in the location, size and shape of lesions — hourly to daily
- Discomfort, pain or burning sensation in some cases, most often related to eating hot, spicy, salty or acidic foods
Geographic tongue can persist for months or years. The problem eventually resolves on its own but may appear again at a later time.
When to see a doctor
Geographic tongue is a minor — although sometimes uncomfortable — condition. However, lesions on the tongue may indicate other more serious conditions of the tongue or diseases affecting the body in general. If you have lesions on the tongue that don't resolve within seven to 10 days, see your doctor or dentist.
