Heat sensitive crown; jaw achey(achy)

I had a root canal & crown a year ago.  With an increased frequency I have noted heat sensitivity for the tooth with the crown.  I have also been having an slightly achey (achy) jaw.  My dentist said my pockets are fine - x ray appears normal.  Would antibiotics solve this problem or does it appear I'll need to get the crown taken off and another root canal done?  Thanks for your responses.

Antibiotics might relieve the symptoms in the short haul but will not solve the problem if the root canal needs to be retreated. I would consult an endodontist for a second opinion.
