Re: Ohhh my aching crowned tooth!!! (after 10 years)
Under normal circumstances, yes, a root canal can be done through the crown. Circumstances do have to be "normal" for that tooth, though. It's done basically as though it were your real tooth.
As with any RC, there can problems, but your dentist can advise you of any after he sees you and determines what they may or may not be.
In other words, don't worry about what may not happen.
Please don't let it continually "re-flare", though. It can only make the procedure more difficult. Once a tooth has become interactive with heat, it needs attention.
Good luck. Please let us know how you do. We LOVE success stories!
My best to you,
