First of all, I have tardive dyskinesia. But, other than that, I have this weird, horrible feeling that there's something behind my front top and bottom teeth. Sometimes it feels like bubbles, sometimes it feels like a rubbery, stringy substance. Many different feelings, but it's always there. I've been to four different dentists and they cannot find anything wrong. I haven't had any x-rays taken. I was just SURE that something was leaking behind my teeth! It is totally maddening, and it appears that I actually do have toungue thrusting. I don't think I would be doing that with my tongue if this feeling wasn't there constantly. My neurologist has given me two Botox shots, and it hasn't done one thing. Has anyone ever heard of this condition? It is driving me absolutely crazy. I isolate because of this. Sandy Surface
