Risk factorsBy Mayo Clinic staff
Studies of factors that may be associated with an increased risk of geographic tongue have produced mixed results.
Factors that are likely associated with an increased risk include:
- Family history. Some people with geographic tongue have a family history of the disorder, so inherited genetic factors may increase risk.
- Fissured tongue. People with geographic tongue often have another disorder called fissured tongue, the appearance of deep fissures, or grooves, on the surface of the tongue.
