Old crown. Very sensitive around it, in fact minor ache in area of tooth and sore ear at same side. Xmas break soon….

Assuming I can get appointment with my dentist, are there any temporary repairs dentist could do before root canal?

I’m assuming decay in what remains of tooth under crown….

Thanks.

Which tooth is it?

I find that dentists generally have to look inside my mouth before they can offer a prognosis. Good luck.

Before I had my root canal done I had my tooth drilled out and packed with something and a temp filling ontop of that for 2 weeks. Assume the packing had something on it to kill off infection. That appointment took no time at all 20 mins. The root canal on the other hand took blooming ages

I think you’ll find that it was probably to kill off the nerve.

Hot and cold affect it?
How long for after thermal stimulus?
Sore to bite on?

Yes if requires root canal will have initial stage done first.

Get an appointment with dentist tomorrow
