I had my tooth worked on over a week ago this wens day will be two weeks, anyways they drilled my old filling out and refilled it with a plastic one after my mouth thawed out I was in pain it went away for about three days after that my tooth just throbs all the time it is so painful, I have to take Advil with ibmotrin in it just to get it to stop hurting it feels like it did the first day they refilled it. I can't eat on that side if I drink it touches my tooth it hurts, what could be the reason for this?
