BMS is difficult to diagnose because its cause can stem from any number of conditions, both physical and psychological. For this reason it's important to consult with your dentist and physician to develop an appropriate treatment plan. Your dentist will begin by reviewing your medical history and asking you to describe the symptoms. He or she may look for oral causes by taking an oral swab or biopsy to check for thrush. He or she may also look for signs of dry mouth. But because BMS is caused by so many conditions, your dentist may refer you to a general physician or specialist for other blood, allergy, liver or thyroid tests.
