Re: deep filling still hurting, I have a question?
What has your dentist said about it?
I'd be concerned about it waking you up at night. If you are grinding during sleep and that's what is causing the pain, then ask for a night guard.
Deep fillings can go either way in a 3 month period. You said 6 weeks right? 6 to go! If the tooth reacts badly to hot, the nerve is definately dying. It's a good sign that the pain is controlled by Tylenol. Good luck.
