However, what happens if an adult tooth gets knocked out? This counts as a serious dental emergency.
If a whole tooth gets knocked out in one piece, there is a limited window (not much longer than an hour) in which the tooth has a chance to be successfully replanted, so the sooner the dentist sees it, the better. To give the tooth its best shot, put it back in the socket on the way there and hold it in place with a washcloth or gauze. If that isn’t possible, store it in cold milk.
Here are a few important don’ts for knocked-out teeth:
Any of these could kill the root, making the tooth impossible to replant!
Most of the time, when a baby tooth gets knocked out, it isn’t an emergency. Typically a dentist wouldn’t replant a baby tooth because that might create problems for the permanent tooth underneath. However, if it wasn’t loose beforehand, we recommend at least giving the dentist a call for some advice. There might be less obvious damage than what happened to the tooth.
