Get a new dentist, get checked out by an endodontist & neurologist! I had similar situation. You'll also find that no one wants to tell you what the xrays say when there's a screw up, and some will even turn you down to help if they don't want involved. But there are doctors out there that are professional & tell u the problem & do the job w/o trashing the colleague that did the work. I have found that the specialist have a better trained eye.
find another dentist...yesterday. my sister had pain and symptoms almost identical to yours(pain up into her nasal cavity, etc) and she needed a root canal.your dentist sounds like an egotistical jerk. the fact that he has not discussed a root canal with you is rather strange, as that is exactly what needed to be done to alleviate my sister's pain, although SHE was the one who thought she had some odd sinus problem. it definitely sounds like your first step to relief is another dentist. best of luck. mia
3.5 years is way too long to go in pain. You should get another opinion. It sounds like you may need a root canal.
