Do you wear an acrylic splint? The burning can be from an allergic reaction to the coloring in the acrylic process. I have tried taking alpha lipoic acid 600 mg daily but has not helped. I am in the process of finding a dentist that can make a hard splint with some other material. I am allergic to some metals like nickle too.
