redone root canal on upper left premolar

I just saw an endodentist to have an infected root canal redone on an upper premolar.
The endodentist  said I needed 2 visits. After the first visit, there was no pain. I could even chew.
Two weeks later (72 hours ago), during the second visit, while he was pushing a needle inside the tooth, there was a sharp pain in spite of the extensive freezing. I wonder if by chance, there was perforation.
Now, 72 hours after this second visit, I still experience a sharp pain under the slightlest pressure. I certainly can't chew on my left side. I wonder if things will get better or if I will need to have this tooth extracted. Please help.

I also am in the process of having a root canal redone by a specialist, although I have only completed the first visit so far (got one more to go).   I don't know if our cases are similar but my ordinary dentist referred me to the endodontist after my dentist had completed the entire root canal back in March.   When the endodontist went down into one of the canals I could feel a sharp pain so I let out a big "OW!"    He told me it showed the presence of a live nerve still there if I was able to feel the pain.   Apparently he destroyed the offending nerve and went back down into the canal just a few minutes later and I couldn't feel anything that time.   Did you let your endodontist know about the pain you felt at the time?   I still can't chew on my tooth either and it's been 17 days since the treatment.   My specialist has told me I need to wait 1 to 2 months for it to settle before he continues the procedure.  I'd be interested to know how you get on.

I am still in pain after 4 days. Trying to reach the endodontist without success so far. It is the week-end...No I did not let him know of the pain at the time. It was just once and I did not think much of it at the time. After reading about root perforation, it suddenly appeared significant. I will keep you informed. Please let me know how things go for you in the future.

I actually phoned my specialist before the weekend because of the pain I've been in and he said in his experience, the more you mess about annoying the tooth once it's had treatment on it, the longer and harder the road to recovery.    I can certainly understand what he's saying, but it's so very easy to say when you're not the one in pain with a tooth!   I've been told I need to wait up to 2 months for it to settle :-(    When he hurt me when he was cleaning the canal, he explained that with the materials he uses, he was able to reach down 1mm further into the canal than what my regular dentist had been able to do a few months ago and that's where the nerve fragment was (or so he said).   I'd be interested to hear what your specialist tells you about root perforation though.

Root perforation is something the endodentist is rejecting as a possibility. Of course he should...that would mean he made a mistake.
This said,  Yesterday( Monday), I have seen my regular dentist and he ajusted my bite.
The pain is a little less after that. He said to wait a week and go back to see him.
I'm crossing my fingers.

That's great that your pain is a little less.   A lot of the time it's just a waiting game with these teeth problems.   Please let me know how it goes over the next week or so.   I'd be interested to know if you're able to chew comfortably on it again soon.   It's been three weeks since I started having my root canal redone by the specialist and I still can't put pressure on that tooth yet.

Things are improving here. Pain is less. Having my bite ajusted was very helpful, I think.
How are you?

[Angel6809]

I guess that means that the root wasn't perforated, which is good.   For me I noticed the pain was getting less after two weeks had passed.   It's now been 3 weeks since the tooth had its first session of retreatment......still one more session to go.    I haven't had to take pain killers for the past week but chewing on the tooth is still not comfortable at all.   It's not pain that I feel though, it's more a feeling that the tooth is very very weak and just can't sustain pressure on it.  I'm wondering if it's because it needs a good strong permanent filling on it, as I've only been having temporary ones on for so long with all the treatment its had throughout this year.  It has a crown on it at the moment that is approx 12 years old and treatment was done through the top of the crown.   The tooth was crowned all that time ago because there was a hairline crack in it back then, so maybe the crack is not being protected by the crown anymore, which could just mean a new crown being fitted.   I really don't know, but I long for the day that I can actually chew something comfortably on the left side of my mouth again!   Still, the pain from the actual treatment has subsided, which I am very thankful for.

Good to know things are improving for you :-)

i notice a small bump on my left side below my tooth on my gums around christmas time i dont no how long its been there.

[attt]

I do not have any more pain. I do not think of my tooth anymore. It's a good sign. Hope things are well for you.

I am not a dentist. See a dentist.

Hey that's great attt !   I'm so glad for you.    Still can't chew properly on mine but the terrible aching has ceased thank goodness.   Took almost 3 weeks for that to happen!  I'm thinking of getting my bite adjusted also as I think the poor sucker is being hit too much by the tooth above it.   Thanks for letting me know how you're doing.
