The major symptom associated with burning mouth syndrome (BMS) is a burning sensation on the tongue, lips, gums, palate, insides of the cheeks or throat. This symptom is often intense, and patients may feel as though they have been scalded with a hot liquid. The pain itself unfolds differently from patient to patient. Some people experience pain that gradually intensifies during the day, whereas others experience pain that is intermittent or constant.

Other symptoms associated with BMS include dry mouth (xerostomia), thirst, mouth soreness, tingling and/or numbness, and a taste disorder.

Patients who experience BMS often report discomfort or restlessness and may experience mood changes, irritability, anxiety and depression.
