Hot sensitivity: A tooth should no longer be sensitive to temperature changes after a root canal. Some teeth will have canals that are very difficult to find, even by the best of dentists. Go back to your dentist and discuss your options. You may consider seeing a root canal specialist, most have surgical microscopes they can use to help locate these hidden canals.

Hard to say: A tooth with root canal therapy should have not sensation to thermal stimulus, either hot or cold. It might be an adjacent tooth. Consult with your dentist to have your other teeth evaluated.

If its the same tooth, then there's a problem. But it could be an adjacent tooth. Get it evaluated.

RCT sensitivity: I will assume that the rct was completed. Properly treated root canal therapy teeth cannot have sensitivity to cold, hot or sweets. If the tooth is still sensitive, it's most likely another tooth. Patients have difficulty sometimes pinpointing exactly which tooth causes pain. See your dentist for an evaluation.

See dds: You probably did not get a crown put on and the root canal broke. Hopefully you can still save the tooth.

The : The 'temp filling' part of your question raises a red flag. After a root canal - it is important to have the tooth properly restored - if a final restoration - such as a crown is not placed on the tooth then the canals that were sterilized during the root canal procedure can be re-infected with bacteria. Reinfection will lead to the kind of pain you're describing.

I : I assume that your root canal is completed. It is not unusual to have some pain after completion of the treatment due to residual inflammation of the tissues around the root of the tooth. This can be managed with Motrin or advil (ibuprofen). I may also be present if there was an infection in the bone as a result of the death of the nerve. If the discomfort does not slowly resolve contact the dentist who performed the procedure for instructions.
