See your dentist: There are many possible answers but an exam will determine the real reason for your problem. You may have a fractured tooth, reinfection of the root canals, a problem with an adjacent tooth, occlusal trauma, etc... Go to a dentist or endodontist for an examination.

See your dentist: In most instances, it is advisable to cover and protect a tooth with root canal therapy (rct) with a crown. Failure to do so could lead to tooth fracture sometimes, which could be the cause of the pain. If no treatment after the rct at all, leakage could even cause the rct to fail. There's even a small chance that it is a neighboring tooth causing pain. Have it evaluated as soon as possible.

Time for a redo: It sounds like either the root canal needs to be redone, or there may be a crack present. If a tooth is not properly restored after root canal therapy, it may cause the tooth to crack due to weakening of the tooth structure. Also, if the permanent filling was not placed in the tooth, there is a good chance that there was leakage in the tooth that may have reinfected the root canal.

Have it evaluated: You need to see a dentist to determine the cause of the pain. Once that is determined, you may or may not have options. If the tooth is fractured beyond repair, you will need to have it extracted. If the cause is a failed rct, the available options would be retreatment, apicoectomy or extraction. Although less likely, it's not impossible that it could be a periodontal infection or adjacent tooth.

Check w dentist: Return to the dentist that did the root canal for you. Evaluate for split tooth, abscess, periodontal problem, problem w adjacent teeth. Don't delay.

Still infected: Your tooth is probably infected or is reinfected. A crown is usually necessary to seal the top of the tooth to prevent bacteria from infecting the tooth. The fact that your tooth does or doesn't have pain is irrelevant as you can have an infection without any pain. Get it checked out. You may need to extract the tooth to get rid of an infection that is in the bone surrounding your tooth.

You have been: Lucky 4 years is a long time for a root canaled tooth to go without a crown if indicated. Don't wait on symptoms. Try to get it done before a fracture.
