I have a top, front tooth that I broke as a child, it was built back up with white composite. It is still alive and doesn't hurt, so I wanted to get porcelain or a veneer for aesthetic reasons. I recently switched dentists, and my new dentist has told me that due to clenching, the backs of my top front teeth are eroding. My front teeth are lightly curved in the back, but I have always assumed that was their natural shape. I have researched Bruxism on the internet, but I don't seem to fit any of those symptoms. No other parts of my teeth are worn down at all. My dentist won't work on my tooth until I have orthodontia to widen my palate, and move my teeth; because they claim I could grind and shatter the procelain. I don't see how this will help, as I have already had braces as a teen. The whole process could take years before my tooth is fixed. I have never heard of such a thing. Is there any truth to their claims, or should I be looking for another dentist?
