After a root canal procedure, is it common to feel discomfort or pain in the gums a week out?

Occlusion: I would have the occlusion checked. This is the way the tooth hits on the opposing tooth. This can keep a root canal tooth sore. Also, make sure there is no more infection around the tooth. Check adjacent teeth for problems. Sometimes these teeth are in trouble and can refer pain to a different area. Another consideration is that root canal teeth can be sensitive for longer than normal.

It's possible: Gum soreness could be the result of the clamp used to hold on the rubber dam or from the injection site from the anesthesia. It could also be a sign of complications with the root canal therapy. If symptoms persist or worsen contact the dentist who performed the procedure.

Not uncommon: It is not uncommon to have some discomfort following a root canal. The tooth itself as well as the surrounding gums and bone ca. Be tender for days or even weeks. I suggest, however, a follow-up with your dentist to ensure everything is healing properly and that no underlying problem is present.

Check bite: Another reason to return to the dentist is that if the bite is too heavy it can cause lots of pain and fracture.

Return to Dentist: This definitely warrants a trip back to see the dentist you used for your procedures.

No: Root canals performed by well trained endodontists have patients which may experience pain after a week. Have it reevaluated. Fractures may sometimes be present but undetected. Additionally there may be additional canals present which are difficult to detect. A cbct scan can aid in determining whether or not these issues are present.
