It can be normal; depends on if you also have an infection, how large is it and/or periodontal condition.
Pain after a root canal does not generally come from the gum. Most pain has to do with the periodontal ligament which is a cabling of soft tissue fibers that grow from the tooth surface on one side and the bone on the other. This is what holds your tooth in its socket but it is also the site of a very sensitive network of nerve fibers that work as the “feeling” organ of the tooth. That is how you can feel a hair between your tooth or know when you are biting down to hard and tells you to put the brakes on. The root canal procedure involves cleaning and enlarging the root canal right down to the end of the root where it interfaces and bumps up against the periodontal ligament— the feeling organ of the tooth. This stirs it up and creates a pain response and especially when you bite down on a root canal sensitive tooth. So, most predictable root canal pain comes from outside the end of the tooth, not the gum. There are a few odd situations where the gum could be involved directly by a different mechanism but too complicated to explain here. Most post op root canal pain is as stated above.
Gum pain can be normal after a root canal. It can be a result of the clamp for the rubber damn placement pinches the gum leaving it temporarily inflamed.
Another reason can be that infection from within the roots spreads to to apical tissues around the root and into the gum creating gum tenderness and pain.
This situation may require and oral antibiotic to help resolve.
Yes, many times there is no pain or slight pain. Sometimes severe pain and swelling. It could be sore from the anesthetic injections or infection or the bite can be off. OTC meds like ibuprofen, acetaminofen, naproxen are often good (I prefer the nsaids). If it persists and check with your endodontist. If it hurts every time you bite down, have the bite adjusted so you don't hit the tooth. Often inflammation will elevate the tooth out of the jaw a bit so you hit it too hard or the temporary filling might be too high.

If done properly a root canal requires the placement of a dental dam. The clamp that hold this device tight against the tooth can put pressure on the gums. Due to the length of time the dental dam is in place during the procedure the gums can be sore for a few days after. You can reduce the soreness with what ever you take for any head or muscle ache. It should resolve in a couple days.
It could be from the rubber dam clamp. I would contact your dentist/endodontist just to make sure.
Gum pain is probably because of the rubber dam clamps that are used to fix the dam. Or if you have a deep decay under the gums that was cleaned & filled with temporary cement. The pain should disappear in a few days - Dr Narkhede

For 1-3 days, it's ok.
Gum pain is not normal after root canal treatment. You should contact your dentist for evaluation.
The gum may be tender or sore for a few days after a root canal.
Hi!

Gum pain after a root canal depends on when the root canal was completed. If you just had the root canal done today or yesterday, then the tissue may be a little sore since the root canal specialist uses what we call a rubber dam, to isolate the tooth and keep it clean. The pain should subside after a day or two. If you have other issues, I would reach out to your dentist or root canal specialist to check the area to make sure there is no infection or trauma.

Hope this helps!
