Broken filling removed, temporary crown placed. tender and sore for a day or two. its been almost a week and the pain came back and intensified a lot. constant throbbing and sensitivity, otc meds dont help, will call dentist, but is this normal?

Depends: If the broken filling had deep decay underneath it that was close to the nerve, then this is perfectly normal. Deep decay often results in the need for root canal therapy. If the pain is escalating and analgesics don't seem to be working, it's time for endodontics. Your dentist knows exactly how deep the decay was.

No: Pain is never normal. It means something is wrong and needs professional attention. Deep decay that reaches the nerve of the tooth can cause the n nerve to die. Large cavity can be precursor for fracture.Or this ay be as simple as the temporary crown being "high." Whatever the cause, you need professional help. Please see your Dentist immediately.
