I'm wondering how long should a permanent dental crown hurt?

Tooth ache?: Sensitivity in a tooth with brand new crown is almost normal, it could last, weeks even months. I am talking about a slight sensitivity, that will go away. This different thna paine, and this is bad news, mostable if you need to take over the counter pain medicines. In that case tooth needs root canal treatment. Ok?

It shouldn't: If tooth hurts may have root canal problem, fracture, or crown may be in hyperfunction. Call the dentist who made the cap for you.

Pain after crown: Sensitivity is not uncommon after a crown is placed. If this goes away, 6-8 weeks, then tooth is recovering and getting back to normal. However, the transition from temperature sensitivity to constant pain is a bad sign. There is a chance you are going to need an endodontic treatment. See your dentist for re-evaluation. Good luck.
