Over a month ago, when my dentist was taking off my temp crown, the build-up including a filling came with it. He went ahead and glued the permanent crown on. Since that time, I have had terrible tooth pain. I was advised to have a root canal by a specialist which I did two weeks ago. Still the tooth with the crown is so painfull it cant be touched and is sensitive to being brushed. After a round of antibotics and then a round of steriods, I dont know what to do next. What could possilbly be the cause?
