Geographic tongue

- This is a relatively common, harmless condition of unknown cause
- The tongue has changing (migrating) areas of inflammation of the tongue with the loss of tongue papillae
- These reddish areas have a map-like appearance and sometimes there is a burning sensation
- There is no predictable treatment or cure but may be triggered or worsened by certain foods
- RInsing with salt water (1 teaspoon of salt in a cup of warm water) may help prevent infection
- Antihistamines or topical anaesthetics may give temporary relief
