Q. Dear Sir, I have recently had a porcelain bridge fitted at the front (upper) as I lost my front tooth to an abscess.I am happy with it cosmetically but as my top teeth protrude the dentist sanded down two porcelain teeth at the back as to avoid them catching the lower teeth. Originally he said they would be remade as I paid privately and he said they would be covered by insurance; but now says he has permanently cemented them. The two porcelain teeth that have been sanded are rough on my tongue and I wonder can they still be adjusted.
