Loss of taste. Those with Burning Mouth Syndrome experience a loss of taste with even the most pungent foods. While this symptom is neither uncomfortable or painful, it proves to be frustrating. Loss of taste removes the joy from eating, and it makes the act of eating even the sweetest foods seem more like a chore than a treat. While no treatments are available to bring back the sense of taste, cognitive behavioral therapy may help with the emotions of frustration and grief that surface as patients learn to cope with their condition.
