Geographic tongue is an inflammatory condition that affects the surface of your tongue, but it's harmless. The tongue is usually covered with small pinkish-white bumps (papillae), short, delicate, hair-like projections. In geographic tongue, parts of the surface of the tongue are missing papillae and appear as smooth red spots, often with slightly raised edges.
These spots (lesions) give the tongue a geographical, map-like appearance. These lesions often heal in one area and then move (migrate) to appear in another part of your tongue. Geographic tongue is also known as benign migratory glossitis.
Although geographic tongue may sound worrisome, it doesn't cause health problems and isn't linked to infection or cancer. Geographic tongue can sometimes cause discomfort and an increased sensitivity of the tongue to certain substances, such as spices, salt, and even sweets.
symptoms
Signs and symptoms of geographic tongue may include:
- Smooth, irregularly shaped red patches (lesions) on the top or side of your tongue
- Frequent changes in the position, size and shape of the lesions
- Discomfort, pain or burning in some cases, most of the time related to eating spicy or acidic foods
- Many people with geographic tongue don't develop any symptoms.
- Geographic tongue can last for days, months or years. The problem often resolves on its own but may reappear at a later time.
When do you see a doctor?
Geographic tongue is a minor condition — though sometimes uncomfortable. However, lesions on the tongue may indicate other, more serious conditions of the tongue or diseases affecting the body in general. If you have lesions on the tongue that don't go away within 10 days, see your doctor or dentist.
the reasons
There is no known cause for geographic tongue, and there is no way to prevent the condition. Geographic tongue and psoriasis may be associated with geographic tongue and lichen planus. However, more research is needed to better understand the possible relationships.
risk factors
Studies on factors that may accompany an increased risk of geographic tongue have led to conflicting results. Factors likely to be associated with an increased risk include:
- family history Some people with geographic tongue have a family history of the disorder, so genetic factors may increase the risk.
- Cracked tongue. Often, people with geographic tongue syndrome have another syndrome called fissured tongue, which looks like cracks on the surface of the tongue.
- complications
- Geographic tongue is a benign condition. It does not pose a threat to your health or cause long-term complications or increase your risk of severe health problems.
However, anxiety about the condition is common because of:
- The appearance of the tongue can be embarrassing depending on how the lesions appear
- It can be difficult to be reassured that nothing is, in fact, seriously wrong
