Q. Dear Dr Glaister. I am desperate for some professional help with my teeth. I would say my general dental appearence is good, however I have a dead single tooth at the upper front. This tooth was banged a few years back and as a result the nerve has shrunk up into my gum. When tested at the dentist I had a cold compression test and did not feel anything. My question is this, at present the tooth is discloured, (a yellow tinge)and due to increased brushing there is a dark mark at the top of my gum line. This hugely affects my confidence and will to smile. I have considered whitening treatments but am worried that because the tooth is dead and more discoloured it will stand out more, I have thought about veneers and other dental surgery but get told different things each time. what would you suggest, im really upset and need some honest, professional advice and direction.,
