Dentistry - How long wil it take to know if my tooth has died?

I recently got a blow to the mouth that has resulted to three of my teeth now not having any feeling in them (about 3 weeks ago). My dentist tells me that the teeth may have died due to nerve damage but said only time will tell - he couldnt tell me how long I should leave it before I would know if they wernt going to recover - any ideas?

If your teeth are sensitive to hot they are dying, if they are sensitive when biting together they could be dying(or have a cavity), cold sensitivity really isn't that huge of a red flag, sharp or dull pains, having to medicate(Motrin, etc.) due to the pain, are also signs they tooth is dying, abscessing is another sign, your dentist should have taken x-rays..........if he did and didn't see anything around the nerve or the PDL you will probably be fine, if he seen something, you should probably go to the endodontist for a consult, b/c more than likely those teeth are going to need a root canal and crowns......good luck!!
Reply:i think if you teeth star changing color like getting dark then you know they are death
Reply:It could happen at any time, you never know how teeth will react to trauma. If you develop hot/cold sensitivity, pain that keeps you up at night or if the tooth starts to become a darker shade, that's a good sign that your tooth is dying.
Reply:sorry but what about if you eat something hard you mite find so pain or something
