Bell's palsy is a paralysis or weakness of the muscles on one side
of the face. It causes one side of the face to droop and affects not only taste
but also saliva and tear production.
In most cases of Bell's palsy, the nerve that controls muscles on
either side of the face is damaged by inflammation. The cause of this
inflammation is not clear, but it may be linked to a viral infection.
