1 month following root canal it hurts to chew hard things, sensitive to touch. What options do I have to treat this?

Hi:
Most likely the bite has to be adjusted and make sure there is no grinding or clenching pressure on the crown as well.  Please go back to your dentist right away to check he bite.
Best,

Hello and thank you for your question. Please consider going back to the dentist and letting him check the area. There may be multiple reasons for the discomfort. He will take an xray and have more information to properly diagnose without speculation. It is considered a post surgical care and, at least in my practice, there is no charge for this service.
