I have a crown and I also experience that "foreign" feeling from time to time. My dentist has checked my bite and the size of my crown, but can't seem to find anything wrong. Could there be a more serious issue going on, such as a problem with my roots? If so, could I get a dental implant with a crown, or would a root canal more than likely be recommended? For some reason I am terrified of root canals, but on the positive side, my
dental insurance would cover part of it as opposed to an implant. Thanks!
