Pain after root canal

Hi, I had a root canal three weeks ago. It got to that point because I am terrified of that chair, but that's another topic. It was on three contiguous teeth, 2 of them molars. They weren't sure if they could save the middle molar, but they were able to finish the root canal. It was the only tooth that actually hurt a lot before the root canal. So after the root canal I got what I would assume is the normal pain you get after a root canal, all good. Yesterday I was eating guacamole, it was very cold, and suddenly I felt a lot of sensitivity, it felt like a nerve started throbbing. It went away but now I got this dull pain and it hurts if I press on the tooth.

My question is: is this normal? Or did they miss a nerve? My appointment for crown prep is next Tuesday, but I'd like to know6if this could be normal because of the condition the tooth was in, or if they missed a nerve. Thank you.

Have your dentist do a cold test on the root canalled tooth. Most likely the cold sensitivity could be from the adjacent teeth.

I think that there is a canal that might have been, inadvertently, bypassed. Was your procedure done by an endo professional? They have high-powered microscopes that can see 3/4 down the canal.
I just had RCT yesterday and the back (distal) root if by lower molar branched out midway into a ‘Y’ configuration.

I'm a retired dentist after 44 years, and I tell you, it would be easy to miss another canal without their special equipment.

In the future, endodontics may incorporate a 3D CAT scan like what is done before placement if an implant. Then, it could take away the drudgery of trying to visualize an accessory canal, or try finding a divot with a curved file and adroit attention to finding a tiny opening. This technology needs to be preferable, nowadays; and affordable.

So, don't have the crown until your dilemma is resolved.

I was eating some cherries today with my daughter, and I almost crunched down on a pit! I had already fractured a tooth on the opposite side- root canal/ crown/ extraction/ implant.

I have provisions to place a temporary ‘core’ which is not only sealing and keeping food out, but adhering to the prepped walls.

But, after I counter-sunk the temporary (Cavit) I experienced a ‘shock’ when I cured the restorative components with my curing light! I don't think it has anything to do with post- cure expansion. U have no clue! Any dentist, please chime in. Thanks.

Root canals can bifurcate and trifurcate like you mentioned. 3D CT scan is very useful to identify these anatomic difficulties. According to a prominent endodontist in Boston, he could only instrument about 60 to 80% of all MB2 canals.

2nd molars get the brunt of occlusal forces and can suffer coronal damage. My #18 has worn halfway down. I wear a custom occlusal guard and my "shocks" have decreased significantly.
