A: The cause of geographic tongue is unknown. Several factors have been proposed as possible causes such as emotional stress, psychological factors, habits, allergies, diabetes and hormonal disturbances. However, none of these factors have been conclusively linked to geographic tongue.
This appearance is the result of indentations of the teeth where the tongue is habitually pressed against the teeth (tongue thrusting, and example of oral parafunction). A lesion similar to morsicatio buccarum can occur on the tongue (sometimes called morsicatio linguarum), caused by chronic chewing on the tongue.
