I’ve had two root canals done, neither of them hurt.
On the first, the tooth was already crowned, but apparently, putting the crown on had irritated the root to the point that the pulp became inflamed and picked up bacteria from the bloodstream (I did not know that could happen), and nerve pulp is apparently a perfect place for bacteria to throw a little party.
I went from “hmmm, my ear is a little tender. I wonder if I’m getting an otitis media,” to “Dear God, just please give me the sweet release of death!” in about four hours. Seriously, I took three Vicodin, and I was still hurting bad enough to cry.
When I saw the endodontist, I’d had enough pain meds over a long enough period of time that I was able to do other things than curl up around my jaw and whimper. As soon as he started the numbing process, it got better, a little more better, and finally all better.
He explained to me that there were a handful of developments that had completely changed the course of root canals. First, dentists began to take pain control seriously and would give enough anesthetic, that the patient just wouldn’t feel anything. In my case, it was three stages - the topical ointment that numbed the gums, the initial shots that didn’t hurt because the gums were numb, and then any necessary follow-up shots if I gave any indication of feeling pain.
Second, endodontists took a page out of neurosurgery’s book and started getting the really big magnifiers, so they could see what they were doing on an epically tiny scale. Some nerve roots are smaller in diameter than a human hair, so seeing at a 100x magnification, it was much easier to spot and remove all the nerve tissue.
Finally, they started doing bleach rinses of the root canal after the canal is opened with filing, but before the gutta percha is put in. The bleach kills off any residual bacteria. The reason so many people had so much pain after a root canal is that a large percentage would have a tiny bit of leftover nerve and a bacterial infection taking over the canal.
So, on my first, I went in terrified, and came out wobbly and relieved.
My second one was an early catch. I had a very large cavity that was getting closer and closer to the root. I put off getting a filling, because I had no coverage and no money. When I finally could, it had gone too far, and getting rid of the cavity (which is not actually a void, but is rotten dentin with the texture of leather) would end up hitting my tooth’s nerve anyway. So, back to the same wonderful endodontist. I was a little jittery, but I came out feeling just fine. Well, except he’d numbed me up so much, I looked like I’d had a stroke - couldn’t smile properly, dribbled water when I drank, couldn’t talk quite right - for another six hours. Not complaining.
If you’re really nervous, classyladyhp, call your endodontist and ask him for a prescription for a tranquilizer before you go in. Diazepam (Valium) and Xanax work wonderfully. If you’re already in pain because of an infected root, and OTC medications aren’t cutting it, ask him for prescription painkillers. A good endodontist will listen to you and take care of your concerns.
