Painful to Touch Molar after Crowning

[Jchalups]

Leading up to a recent crown, I had pain in an upper molar. The tooth felt at the time as if a part of it was dying. My dentist performed a root canal (finding an additional root at the time). While the temporary cap was on the tooth awaiting my  new crown to arrive, I noted to him that the tooth still had some sensitivity. So much so, that when he tried to remove the temporary cap, it was necessary to dumb the area. The tooth is now with a new crown and still remains very sensitive to the touch. If I carefully bite on the upper molar, it can endure chewing of soft foods, but not without some pain. I am a night-time grinder, and thus the reason for this crown per my dentist. I can jiggle the tooth with my fingers and create the pain as well. I wear a soft splint at night to assist in removing pressure in my grind while I sleep. I am taking Ibeprofen to try to reduce the throbbing and sensitivity to touch. I cannot tell you how painful touch it with metal is. Not only to remove the temporary cap, but now with a fork to "test" it while I'm eating, it is a sensation that is something like I have never experienced prior.
Thank you for your consideration and help in this.

What are your thoughts? My dentist has never seen anything like this.

Tooth sensitivity to percussion or force is normal after optimal canal obturation. Sensitivity tends to subside in a few days to weeks. Seeing an endodontist to have a through evaluation is advised if sensitivity persists more than 4 weeks.

Thank you for your response. I have now developed a bump on my gum just above my root canal/capped tooth. Sensitive to touch, it throbs on occasion. It is sensitive on the outside of my face to touch at my cheekbone. Could this be an abcess (abscess)? I do not know what an abcess (abscess) is, but think this might be one. I am still (Dec. 12) unable to bite on the side of the tooth that was repaired. Thoughts? Thank you for your consideration and assistance. I am unemployed and do not want to go to the dentist unless I must due to the cost of treatment. The canal was $800, and that depletes my cash for the month (and more). Thanks. Jean

Good call on the endodontist. He checked my tooth today. Shows perhaps another canal. Will reduce the root canal on Jan. 8. 83% chance of saving the tooth. Anyone with pain, and then infection (bump and soreness of the gum) should go directly to the endodontist. Please note, that the specialist is not cheap. My evaluation was $75, and now a double root canal (this second one) will double my costs. But, trust me when I say saving tooth is worth all the money in the bank. Again, thank you. Jean
