Knock out a tooth? Put it in cow's milk before going to the ER.
Tooth knocked out? Immediately get to the emergency room, or dentist, to increase your odds of saving the tooth.
Make sure to place the tooth in whole milk to keep it from drying out before getting into the car.
If you don’t have milk, saliva works too, so place in the tooth in your cheek – just do your best not to swallow it.
