Q. I have been experiencing toothache for the past three weeks or so. Before this I had have a dental exam wherein the dentist told me he’ll see me in 6 mths. Snce then I broke a tooth which turned out to be a dental carie. I had it filled and since then still am having discomfort. I am now convinced that it is the tooth beside it as it looks dark when I lift the gum during flossing. An x-ray was done which appeared normal. I have looked at the BDA website and others on dental caries and am now convinced that this tooth is the real dental pain problem. It is distressinf in that now I think the decay was visible on the x-ray, although we were looking at the tooth with the filling not at the one beside it. Am I being overly worried that this may have been missed and I may now need two root canal treatments instead of one? I have been using Diclofenac and Co-dydramol for pain relief for the last two weeks. I am also on Metronidazoe which my dentist has prescribed a few days ago. I would be grateful for your insight on this please.
