Hello,
Geographic tongue is a benign condition that usually resolves itself without causing any problems for the patient so most people do not require treatment. There is no known cure. If there are associated medical conditions, treatment of these may improve the appearance of the tongue.
Discomfort may be treated with a mouth gargle or rinse containing antiseptic and anaesthetic agents. Topical corticosteroids may also be helpful for occasional use eg. triamcinolone in dental paste applied several times a day when required.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
