Find the tooth. Only rinse the tooth if it has dirt on it… do not scrub the tooth or clean it with anything other than water. If possible, holding the tooth by the crown, replace the tooth into the socket and hold it there with gauze or a clean wash cloth. If you cannot put the tooth back into the socket, place it into a clean container with either milk, or the child’s saliva. Get to the pediatric dentist’s office quickly (or call if it is after hours). Your chances of saving the tooth increase the faster you act.
