Find the tooth and rinse it gently in cool water (do not scrub or use soap). If possible, replace the tooth in the socket and hold it there with a clean gauze or washcloth. If you can’t put the tooth back in the socket, place it in a clean container with milk, saliva, and water. Then call your dentist office immediately! Call the emergency number if it is after normal hours. The sooner you see the dentist, the better the chances of saving the tooth.
