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.
