Thank you both for your replies. I appreciate your empathy and advice. The pain seems to be subsiding somewhat. Yesterday it was unbearable but today it is less severe. The pain behind the root canaled tooth has also diminished. Slight irritation, but better. The pain up in my mouth is far away from the root candled tooth and an oral surgeon (friend of the family) said today, it appears to be a muscle issue. I have a very irritated muscle up in my mouth, perhaps from all the work done recently. I also have developed TMJ, as my bite is very much out of whack from the wisdom tooth removal, etc. I am going to try to wait it out before extracting the tooth. I figure i want to exhaust all options before losing this tooth (and the bridge) entirely - which seems to me, could be quite traumatic and lead to months upon months of surgery for implants to replace the molars, etc. Thank you again and I do hope my pain continues to subside. I appreciate your advice greatly.
