So my dentist suggested crowning the tooth
as the next step. It would appear that the nerve
is still fine, it's not too sensitive
to hot/cold (not more than other teeth), it's just biting down that causes pain. He doesn't seem to think that root canal treatment was neccessary, but now that the tooth is prepped and a temp crown is on it, it's still painful when biting and I don't want to end up with a permanent crown that will need to be taken off for a root canal treatment.
