While many people with MS experience numbness and tingling at some point, you may or may not have heard of or experienced numbness and tingling of the mouth—a particularly unpleasant sensation. In multiple sclerosis , mouth numbness, like other sensory disturbances, is associated with a damaged or destroyed myelin, the fatty sheath that insulates nerve fibers. It generally occurs from a lesion in the brainstem and may affect the face as well. One study suggests also using trigeminal somatosensory evoked potentials as a diagnostic tool. Due to the numbness, some people may begin chewing and holding food on the unaffected or less affected side of their mouths. Others may lose their appetite due to the unpleasant experience of eating—it's especially important to talk to your doctor if this is the case. There is no specific medication to treat mouth numbness.
