What in the World is Geographic Tongue?
Picture this: You’re feeling some mild irritation in your mouth, which seems to be coming from the area near your tongue. You go to the mirror, open wide… and notice a series of red patches on the tongue’s surface, which are surrounded by whitish borders. Should you drop what you’re doing and rush to get medical help right away?
Sure, a visit to the dentist might be a good idea to rule out more serious problems — but first, sit down and relax for a moment. Chances are what you’re experiencing is an essentially harmless condition called “benign migratory glossitis,” which is also known by its common name — geographic tongue. While it may look unusual, geographic tongue isn’t a serious condition: It’s not cancerous or contagious, and it doesn’t generally lead to more severe health problems. However, it can make your tongue feel a bit more sensitive, and may occasionally lead to mild sensations of burning, stinging or numbness.
The appearance of reddish patches on the tongue results from the temporary loss of structures called papillae: tiny bumps which normally cover the tongue’s surface. These patches may appear or disappear over the course of days — or even hours — and sometimes appear to change their shape or location.
What causes geographic tongue? Several factors seem to be responsible for setting off the problem, but as of yet the actual cause of the disease is unknown. Among these triggers are emotional stress and psychological upsets, hormonal disturbances, and deficiencies in zinc or vitamin B. The condition, which affects between one and three percent of the population, is seen more frequently in non-smokers, in women, and in those with a family history of the problem. It is also associated with people who suffer from psoriasis, a common skin condition, and those who have a fissured (deeply grooved) tongue.
Unfortunately, there is no “cure” for geographic tongue — but the good news is that treatment is usually unnecessary. If you’re experiencing this condition, it may help if you avoid foods with high levels of acidity (like tomatoes and citrus fruits), as well as hot and spicy foods. Alcohol and other astringent substances (like some mouthwashes) may also aggravate it.
While geographic tongue isn’t a serious condition, it can cause worry and discomfort. That’s why it’s a good idea for you to come into the office and have it checked, just to make sure. A thorough examination can put your mind at ease, and rule out other conditions that may be more of a concern. We may be also able to help you manage this condition by prescribing anesthetic mouth rinses, antihistamines, or other treatments.
