why did the dentist waste your money on a root canal on a wisdom tooth?
It sounds to me like the nerve in the tooth with the crown is non- vital, which means the nerve is dead and that the tooth needs root canal therapy. I would get to see him asap.
the pain you are having (ie extreme sensitivity) is not consistent with pain from a tooth that already had root canal. It sounds like it is coming from the tooth that has the crown (I am assuming that root canal therapy has not benn done on this tooth). I would see a root canal specialist to evaluate the tooth that is bothering you-- which seems NOT to be the tooth that already had a root canal procedure. He can check the wisdom tooth also while you are there.
one of the teeth may have a fracture
Thanks Mike,
Both teeth have had root canals. The root canal procedure occurred before he crowned the tooth. I will be at my dentist's door bright and early. I am also experiecing a slight fever today.
