My mom just had a filling done yesterday and her tooth still hurts her. I do not understand why she should be in any pain. When I got a filling done I was in no pain and the same with some other people I have talked to. Did the dentist do something wrong? She been going to the same dentist now for well over ten years and never had such a problem. However she is having pain issues with the tooth he did a filling on. Should she go back to the dentist and have him fix the tooth. Or is it something that will pass if she waits it out?
