Rinse the knocked out tooth in cool water. Do not scrub the tooth. If possible, replace the tooth in the socket and hold it there with clean gauze. If you can’t put the tooth back into the socket, place the tooth in a container of milk (water if milk is not available.) Come to our office immediately. Feel free to call our emergency number if it is after hours. The tooth has a better chance of being saved if you act immediately. If you cannot go to a dentist, go to the ER.
