[|Human|] I have a large knot on my jaw bone 3 weeks s/p a root canal. They had a very difficult time getting me numb for the root canal and I had to go back after taking a round of steroids. I recieved a lot of shots of novacaine, but they finally got it done. I now have a large, painless, knot that has developed on my lower jawbone. I noticed it about 5 days ago.No pain associated with it and its hard, does not move, no pain w/ palpatation. I returned to the Endodontist who said it was just my jawbone and probably had always been there. I didnt like that answer so went to my regular dentist who took and xray. A dark area showed up, but they werent sure what it was. He said to watch it for pain and increasing in size and return in two weeks. Im just looking for insight into if this could possibly be related to my root canal or something more serious.
[|AI|]  Dear friend. Thanks for sharing your concern. As per your history given, it appears to be an abscess developed in the periapical area, as your x-ray shows radiolucency there. If it is your jaw bone, it will appear as opaque object and not a radiolucent one. But since there is no pain, it might not be infected too. In this situation, it is better to wait and watch for a week, if it progresses, with pain and pus, please revisit your dentist, else it should recover, if due to anesthetic injection or any inflammatory lesion. Hope it helps. Thanks. Take care.
