Tests and diagnosisBy 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
