Dentistry/post root canal pain at the tooth's apex


I had a root canal. Ten days later saw the endodontic tech to have the tooth filled.  The pain in the tooth's apex was still sensitive.  He did another root canal...ten days later the same result...pain in the tooth's apex tip was still present...some improvement however. Tooth was not substantive enough to do more surgery. Dentist filled the tooth and I took amoxicillin (500mg) for a week in hope it would clear up the sensitive gum area at point of apex tip. It is not very swollen or red. But it is mildly sensitive to touch. I am proceeding with the crown in hope the pain will eventually subside.

Any suggestions on how to cure the pain if surgery is not an option and antibiotics don't seem to help?. Will the body's
own immune system eventually heal the infection...if so, how long will that take?  


Dear barry,

Make sure that this tooth is adjusted to be slightly out of your bite.  It may be that the bite is high.  It may be that you needed antibiotic.  In either case, most likely the pain will subside over time.  I would postpone the crown until the pain has subsided.  Just don't touch or chew with this tooth until it feels better.
