Risk Factors of Geographic Tongue
NORD reports that migratory glossitis occurs in about 3 percent of the population, with females being more prone to it than males. It also affects younger adults more frequently. It seems to run in families, so there may be a genetic link. People with a fissured tongue, a condition where the tongue is deeply grooved and has a wrinkled appearance, may also have a higher risk of developing this migratory glossitis, as can those who have a vitamin B deficiency or have the inflammatory skin disease, psoriasis.
Even though there are certain disorders that often occur along with geographic tongue – hormonal disturbances, emotional stress, juvenile diabetes, allergies and Reiter's syndrome – there is no real proof that they play a role in causing it.
Geographic tongue cannot be prevented or cured. Always keep your mouth clean, stay away from irritating foods and appreciate how special you are to have such a unique but harmless condition that not many people have experienced!
