I have been in a lots of pain. One of the pains was that my bridge was ill fitted but dentist still says it my nerve. But I asked her do it again to see yesterday which now feels a lots better but all my veneers feel very sensitive and I can't bite down on them! Also I have dark shades coming up in between my veneers I ask her why after four weeks! She it something I'm drinking which I don't agree with. Can someone please help me with this? ( attach photo)
