T.F.
I've had a couple of root canals, one twice on same tooth!!
It is not fun, it hurts afterwards as well. I don't know the "norm" of pain.
If you had root canal today.... Give yourself a couple of days minimum to get to a semi normal feeling.
My mouth does not numb well ( lol) as in I typically feel things much more and sooner than normal. I get double dosed with numbing meds and I have 100% feeling in record time. Lucky me!!!
If you feel you are not within the norm of what the dentist told you for expectations post root canal... Call them!! They want you to be ok and have as little pain as possible.
My dentist is very open and welcomes any call of concern after any procedure. Gees... He woke me one night ( pain med induced sleep) to make sure I was ok.
