Glossodynia or burning mouth syndrome (BMS) is a condition characterized by a burning or tingling sensation on the lips, tongue, or entire mouth.
Typically, there are no visual signs like discoloration that help the diagnosis.
Possible causes include nutritional deficiencies, chronic anxiety or depression, type 2 diabetes, menopause, oral disorders such as thrush or dry mouth, or damaged nerves (specifically, cranial nerves associated with taste).
This conditions appears more often in women, specifically women after menopause, than men. Pain typically is low or nonexistent in the morning and builds up over the course of the day. Low dosages of benzodiazepines, tricyclic antidepressants or anticonvulsants may prove to be an effective treatment.
