A burning sensation on the tongue may be a symptom of burning mouth syndrome. Burning mouth syndrome is characterized by a burning pain, and its cause may be due to the irritation of the mucous membrane of the oral cavity due to root stumps, crown stumps, bad prostheses, or drug allergies, heavy smoking, or excessive alcohol consumption, which may cause such symptoms in the tongue. In addition, it may also be caused by menopausal syndrome, diabetes, vitamin deficiency. Usually, local treatment is needed to eliminate local irritants, and to self-examine for bad oral habits, and to avoid smoking and even alcohol. At the same time, systemic diseases such as diabetes should be actively treated, while those with significant surface pain can be coated with 2% lidocaine or 0.5% dacronin, which can reduce pain. If it is caused by mental factors, you can use glutamate to regulate the mind and nerves appropriately.
