Burning mouth syndrome (BMS) is a chronic disorder for which a definitive etiopathology is not known. The BMS patient often experiences a continuous burning pain in the mouth without any clinical signs. This confusing condition can create frustration for both patient and practitioner. Ultimately, it is important for the practitioner who treats head and face pain to become knowledgeable in the recognition of the many complexities and various presentations associated with BMS. In doing so, the practitioner can be better prepared to help patients cope with this confounding disorder and gain a better quality of life.
