What causes geographic tongue?
With Geographic tongue some of the muscle fibres that cover the tongue are missing in the red areas and are overgrown in the grey/white borders. It tends to heal and then recur. This gives rise to the appearance of a map changing on the tongue eg hence the name migratory glossitis. It may last for months or never really disappear.

Who has a geographic tongue?

  • About 1 to 4 % of the population has geographic tongue.
  • It tends to run in families.
  • More common in males and in adults.
  • It is more common in people who have psoriasis, however if you have a geographic tongue and not psoriasis you probably wont develop it. It is also more common in people with allergies and eczema.

Are there any problems with having a geographic tongue?
Usually a geographic tongue is painless. If you have a painful tongue you should consult the dentist or doctor. It is possible to get a similar appearance with a Candida infection but this is usually quick in occurring and painful.
Stress is believed to trigger a geographic tongue. Other trigger factors may be alcohol, tobacco, spicy foods, and citrus fruits.
