The time it takes for burning mouth syndrome to improve varies from person to person, usually improving in about a month with treatment, or in about half of the population within 6 to 7 years. Burning mouth syndrome is a disease that occurs in the oral mucosa, mainly in the tongue as the site of onset, manifested by burning pain, dry mouth, tingling in the mouth, and bad taste in the mouth. The specific etiology of this disease is still unclear, and may be related to neurological lesions, neuropsychological factors, nutritional deficiencies in the body, excessive oral irritation and other factors. The treatment of this disease currently lacks special effective therapies, mainly through the elimination of triggers, medication, cognitive therapy, etc. to improve the symptoms of the disease. Although it is difficult to cure this disease in the short term, most people can improve their symptoms within one year after treatment; a few patients can return to normal, and those who are more difficult to return to normal will gradually tend to stabilize their symptoms. It is recommended that people with related symptoms should consult a doctor in time, and actively carry out related treatments, so as to improve the disease.
