Tests and diagnosis

By Mayo Clinic Staff

Your dentist can usually make a diagnosis of geographic tongue based on an examination of your tongue and your signs and symptoms.

During the exam, your dentist may:

  • Use a lighted instrument to examine your tongue and mouth
  • Ask you to move your tongue around in various positions
  • Gently touch (palpate) your tongue to check for tenderness or unusual changes in the tongue's texture or consistency
  • Check for signs of infection, such as fever or swollen lymph nodes in the neck
