Geographic Tongue is Benign and Harmless
Geographic Tongue is the layman’s term for benign migratory glossitis. The dorsal surface, or top side, of the tongue is covered with tiny finger-like papillae. These sometimes are lost and grow back, usually within several months, and appear to have changing “geography,” therefore the nickname of geographic tongue. This condition is harmless, does not lead to other diseases, such as cancer, and is rarely symptomatic. The area(s) that are denuded of their papillae are slightly red and a very small few may have a burning sensation, usually in the presence of acidic foods, toothpaste, or even the whitening gel used to whiten teeth.
Less than 5% (more like 2-3%) of the population, usually women over 40 years of age, develop geographic tongue which sometimes may possibly be associated with hormonal imbalance such as low thyroid. No one knows for sure. If there is rare discomfort, the recommended treatment is the use of NSAID’s (Non-Steroidal Anti-Inflammatory Drugs) such as Motrin, Ibuprophen, Aleve, and the like. The condition is usually self-limiting but may recur from time to time.
It is important to remember that this condition is harmless and non-contagious, although it is usually frightening to the patient when they first notice it.
