Burning Mouth Syndrome, or BMS, is one of the most embarrassing conditions out there. Those who suffer from it describe burning sensations in their mouth and a foul taste that doesn’t go away even after rinsing with water or brushing teeth. Burning Mouth Syndrome can affect any area of the tongue, gums, lips, or inside of the mouth (from back to front). It can happen to anyone at any time, including children and adults of both sexes.
