Probably not: If it is definitely the same tooth it sounds like a canal was missed-upper molars can have 1 to 5 or 6 canals. The fact that you feel hot indicates that there is still live tissue inside. See your dentist to determine if there is in fact another canal or there is the possibility of referred pain from another tooth. I would recommend having it evaluated by an endodontist-a root canal specialist.

Root canal hurts: The first thing your dentist needs to check is the bite. If the bite is off you will be sensitive to hot and cold and maybe have a dull ache or inflammation and bleeding around the gums. You be clenching or grinding at night that can make it worse. It can also be a tooth next to it, ask your dentist to evaluate.
