Good Morning Janet,
I hope your dentist can take care of this quickly for you. Tooth pain is the most miserable pain there is

. And yes, it is so annoying to have to remove a perfectly good crown. Maybe, if you go to a specialist, they can save the crown and do the root canal through the crown. I had an accident years ago and had to have a cap put on a front tooth. The endodontist was able to drill through the crown and do the treatment and fill the hole she made after that. But this was a front tooth, so I don't know if this is possible on a molar. It doesn't hurt to ask though. Best wishes and good vibes to you!!!
