Root canaled teeth are unable to transmit any pain to temperature because there is no nerve in the tooth that is capable of carrying that signal. If you are having pain to temperature in a root canaled tooth,the problem is with your bite.This is further confirmed by the fact that your opposing tooth is hurting.The pain is actually coming from the periodontal ligament that surrounds the tooth. This ligament is innervated through the bone and is a different nerve source than the tooth's nerve source. A simple bite adjustment by buffing the filling or cusp of the tooth in question should get you some immediate relief. If you are a grinder and these teeth are in hyper occlusion, the pain gets worse. If you have no swelling,the most likely cause is your bite.It is an easy fix.

clarification : With respect to the root canaled tooth, it is sensitive to temperature, meaning if i eat or drink something hot the tooth begins to ache. The indication I got from my dentist was that the root canal probably has to be re-done... So if you are saying that the root canaled tooth can't transit any pain then why does the root canaled tooth immediately start to ache, when it is exposed to hot or cold, but it doesn't ache at all when biting or chewing on food that is room temperature?
Dentist: Dr. Katz, Dentist (DDS or equivalent) replied 4 months ago

If the root canal was done by an endodontist,it is highly unlikely that there is any nerve tissue still inside of the tooth.It is their job and their only job ,to do root canals. If there is pain to hot and cold,it has to be coming from the ligament around the tooth. A root canaled tooth is physiologically incapable of transmitting pain to temperature.

There is some excursion of your lower jaw that is hitting this tooth abnormally.

Do you have any missing teeth that have not been replaced? Do you grind or clench your teeth?

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
