its actually called geographic tongue. I have it. when its really bad i use salt water and it seems to get better.

Geographic tongue is the appearance of whitish striations or circular patches on the surface of the tongue, the consequence of either mouth-breathing during sleep or poor fitting dentures. It is harmless and is not associated with a bacterial infection of any type. The presence of canker sores is thought to arise from a virus, again not associated with geographic tongue

While geographic tongue is a common occurrence, it does not mean that what you're observing is necessarily geographic tongue. People who have been prescribed certain antibiotics can experience an oral yeast infection which can be similar appearance to geographic tongue. Relief is gained by swishing a teaspoon of vinegar in the mouth each morning for several days until the patches are gone.

In cases where the patches are chronic and unchanging from day to day, are located on the inner palate or soft tissues, Leukoplakia is also a consideration.

If symptoms remain for more than 2 weeks, it's always wise to discuss symptoms with your primary care physician. Additionally, internet forums and any information posted in response to questions should never be construed as medical advice, nor supplant the need to be directly evaluated by your doctor.
