Patient discussion about root canal
Q. How much does a root canal hurt? I have to get a root canal for my bottom tooth. I was wondering how much they hurt. And do you have any suggestions that help distract from the pain? Thanks.
A. i did one about two years ago- even the injection wasn't too bad! didn't feel a thing. but after the anesthesia worn off it hurt. but then the dentist told me to take Advil or any other NSAID and it helped.More discussions about root canal
