I have not been able to wear my bottom plate since I came home from the dentist 5 years ago. I have no problems with my top plate except for the fact that I have to use an adhesive every morning. I have tried using it with the bottom plate also but nothing works, I just can not get it to stay put!! Out of frustration, I threw it away long ago!! I have thought about getting a few of the screw in teeth and getting a partial to fit in with these for the bottom, but I don't know how well that would work either. Any thoughts on this would be greatly appreciated.
