Q. Dr Moore, My wife attended the dentist last month for a routine check-up. The dentist told her that she needed a filling and made another appointment for her to attend for this. later on, after having the filling done, she was havig a lot of pain. She went back to the dentist and he told her that he would have to remove the nerve from this tooth. My wife was still having a lot of pain. within the last week, her mouth & face has swollen causing her extreme pain. She went back to the dentist again and he removed another nerve from a tooth at the front of her mouth. I am very concerned that my wife has been suffering with pain for several weeks now as a result of attending the dentist for a routine check-up. Is this normal?
