Tooth still is very sensitive after root canal

    Hi, I posted on this back about 5 months ago but it is still bothering
    me so I'm back again.

    This is the history:
    I had some sensitivity with #30, went in for an xray, was told I needed
    a crown.

    The dentist did xrays and said it was iffy as to whether I needed a
    root canal or not, but it might be a good idea to get one before doing
    the crown as opposed to doing it after wards, but it was my choice.

    He sent me to an endo who did some tests and said he also could not be
    100% sure but he was leaning towards it needing a root canal.

    I went with the root canal. It was a very difficult one (on my end;
    i.e; very painful, long session)(others I had before were a snap
    compared to this one; this was one of those that give meaning to the
    fear people feel when you utter the words "root canal"). After it was
    over, I continued to feel sensitivity there. Called the endo and he
    said he looked at the post-endo xray and he was sure it was fine, the
    sensitivity will go away with time.

    A month passes, I still feel sensitivity. Like when I tap it with my
    toothbrush, it hurts, not a sharp horrible pain, but a small
    uncomfortable pain. I insist on going back for him to look at it,
    again. He takes another xray or two, looks at it, does some testing on
    it and says it's perfect.

    Meanwhile I also went to a new dentist and had this dentist look at
    xrays of it. She said it looked to be a perfect root canal.

    So here I am 5 months later, and this tooth STILL is very sensitive to
    being hit with my toothbrush, tapped with my fingernail, spoon, fork,
    etc... Granted, it's no big problem, but I keep thinking there MUST BE
    SOMETHING WRONG or why would I feel something in a tooth that has no

    Am I just being a hypochondriac about this tooth? is it just normal for
    a tooth to have post-root canal sensitivity for 6 months or more? (I
    use sensitive toothpaste and have for a few months.)

    Any advice or opinions is welcome. Thanks in advance.

    So, when I explain my symptoms to the endo, and he says it's no
    problem, there's nothing wrong, is he just b.s.'ing me, and he knows
    there is some "occult fracture" or such and that the rct was a failure?
    OR does he really think it is fine, that this is sometimes "normal"?

    And are you saying that the tooth may prove to be fine, even though it
    hurts a little sometimes when tapped, that it MAY not have to be
    extracted or gone back into? that it may just be this way the rest of
    my life, or might calm down?

    Or, is it just a matter of time til it has to be extracted?

    Thanks for your time!

  3. On occasion this sort of thing happens. I encounter a patient like this
    on average maybe once every 3 years.
    Sometimes there is an unfilled canal sometimes a fracture. Sometimes
    its an adjacent tooth that is giving the pain, Sometimes its the bite
    either the new crown is too high or the tooth is in a traumatic bite.
    Like Dr Bornfeld says time will reveal the cause. Having a root canal
    look pretty on the x-ray does not mean that the problem was solved.
    I believe you should wait before considering drastic unscientific and
    desperate measures such as extraction because if the problem was not
    the tooth you can not put it back.
    Did you have a new crown placed over the root canal? If so what type
    was it? you may also want to make sure you have good contacts on either
    side of the crown. You can check this with floss, the crown should
    floss like your other teeth. If the contact is not as tight food
    impaction can irritate your gums and give you the symptoms you describe.

    Thanks much for the info.

    Figures, I'd be one of these "once in 3 years" patients. Luck with
    dental work is something I seem not to have at all.

    It's not the bite: there is no opposing tooth on this crown! I am in
    the process of beginning to get implants but as yet there is no bite

    I am not considering anything drastic. I intend to live with it. I
    just wondered if there was any recommended treatment or tests I should
    get. I see that the recommendation is to just wait, so that is what I
    will do.

    I did have a new crown placed over the root canal. what type?
    Porcelain, I believe. Is that what you mean? By "food impaction" you
    mean, is food getting stuck in between the new crown and the old tooth
    next to it? I'm not sure but that does not seem to be the case.

    Before I got the new crown I had a temporary crown on there for
    awhile. The temp crown bothered me more, and then after a while, it
    calmed down to almost nothing. For some reason the permanent crown
    bothers me more than the temp. did and is not calming down as quickly.
    I wonder if it might be because there was more trauma involved in
    installing the perm. crown? I mean, they screwed around with it a lot
    getting it to fit right, put in on and off several times, etc...

    Anyway, apparently there is really nothing I can do but wait ... and
    HOPE that the sensitivity goes away and that I do not lose this tooth!

    I have the same situation on tooth #19 where I had a root canal done on
    a tooth with an existing gold crown. about 8 months ago. It's slightly
    sensitive to percussion, like tapping on it with my finger, both on the
    top of the tooth and on the side. But surprisingly, it doesn't bother
    me when I eat, even something like almonds.

    I know that it is not a problem with any remaining pulp because any
    sensitivity to cold (which is what I had before) is completely gone.

    The endo told me that what I was most likely sensing was the ligament
    adjacent to the tooth

    This must be a common problem because II also had the exact same thing
    on #30 after an RC was done, i.e. no more cold sensitivity but
    sensitive to percussion. This tooth, though, was utlimately replaced
    by an implant/crown so no more problem.

    is this correct - or could be correct - in the opinion of the dentists

    check the bite, it might have a premature contact or interferance? in
    that case syntoms are pain, sensitivity to cold drinks and hot
    drinks....the Dr needs to check the lateral movements and see if
    there's no interferance

    I had an elective root canal 3 months ago. There was no infection but the dentist had drilled to the pulp and said a root canal was "safer" than just a cap. So I agreed to a root canal but now regret it. My tooth is slightly loose which it wasn't before and also a bit painful when I push it with my finger. Sometimes I also have a mild toothache from beneath the tooth. Evidently there's still some inflamation of the tendons. I went in for "adjustments" after 6 weeks and he trimmed the cap back slightly so there's no contact whatsoever. He also said the tooth would tighten up in time. So far it hasn't. I can live with this but it's a bit of a nuisance. I'm hoping for improvement in the coming months. If there's no improvement in a year or so then I'll have to consider having the tooth pulled and a bridge built.

    Experiencing the same thing, googled "sensitivity after root canal" and found this forum. I had an RC on #14 just about 6 weeks ago, and have recently been noticing sensitivity. I mentioned it to my regular dentist (periodontist) today, and she told me I couldn't possibly be feeling sensitivity, since the nerve was removed. The sensitivity is concern enough, but now I'm also worried that my dentist is clueless.

    I had somewhat similar experience and based on a tel conversation with a friend who is experienced dentist he thought that it may well be related to the food that get stock between the teeth and the solution that seem to be working is to clean the area carefully including the use of inter dental brush and anti bacterial mouth wash.

    Good luck

    I am having the same problem and my dentist says "give it more time." I had a root canal about 2 months ago, everything felt fine. Temporary put on, everything felt fine. Permanent put on, tight fit until teeth adjusted. Since the permanent The tooth is either slightly sensitive to percussion and eating some soft foods. Like the other poster said, almonds, hard food no problem. I also feel a mild "pressure" toothache above and around the tooth sometimes. has anyone had any resolution?

    Jim, I have exactly the same problem. I had a tooth that gave me absolutely no problems, but the dentist said I'd needed a crown, so after a couple of visits, he convinced me to have a crown. After the permanent crown was put on, I started getting sensitivity to hot and cold, so they he told me I needed a root canal, which I had done. After almost 3 months, I'm still having sensitivity to touch and tapping as you mentioned (not hot and cold though). I went back to the dentist yesterday..pretty annoyed as I wish I'd never touched my original tooth. He said to try antibiotics, or they could then do a procedure where they go in and clean in out, and finally, if that didn't work, an implant! Good grief! Not having dental insurance, this has been a most expensive procedure. Oh, by the way, they did the root canal through the crown.

    Jim, I know it's been a while since you posted, but do you have any updates?

    I had a similar situation: cavity under old crown, put on new crown, then problems with tooth pain and sensitivity to hot and cold so had another dentist do root canal then now same area very sensitive to tooth brushing and touching, can't chew on that side, not sensitive to cold or hot, don't know what to do but to give it some time, trying to rule out other possibilities like sinuses, doing neti pot, doing allergy shots, don't know what else to do - after spending all that money on the crown, then root canal you are back to square one! Anyone have any ideas?

    I am reading this thread and I have a similar issue regarding sensitivity after having a root canal and crown on upper tooth, second from the back of mouth.

    It's been roughly a year now after having the root canal/crown done, and now the tooth is extremely sensitive to cold fluids; however there is no pain to pressure or touch. I have to avoid the side of my mouth when drinking cold water because the pain shoots up through the nerve.

    The hygienist ran some tests by spraying cold water and/or air. She expected that I was reacting to sensitivity due to my adjacent back molar, which previously had a cavity/filling. To her surprise, I did not react to the cold in either adjacent tooth to the crown/tooth canal tooth. She explained that I only reacted when she sprayed on the "buckle" (excuse me if the term is incorrect) of the crown.

    The dentist was notified of this issue, but she immediately said it is impossible to be the crown tooth, and that it had to be the adjacent tooth with filling reacting. The dentist did not even investigate the situation, but rather just advised me to rub sensodyne toothpaste on the area.

    Should I be concerned? Also, I should mention that I was sent to a specialist to have the root canal. I know that the tooth caused him some trouble, because he ended finding an additional canal half way into the process. The dentist (not the specialist) did the filling and crown.

    My feeling is that the dentist is trying to brush this off, because she wants to avoid going a redo -I spent ALOT of money out of pocket for this job, and I want it done right.

    If anyone can advise on what I should do, I'd really appreciate it!
