For permanent teeth – Find the tooth. Handle the tooth by the crown, not root. If the tooth is dirty, gently rinse it in cold water, but DO NOT scrub or handle the root unnecessarily. Try to replace the tooth into the socket. Have the child hold the tooth in place by closing on a gauze pad or washcloth. If it is not possible to replace the tooth, place the tooth in a cup of milk, or the child’s saliva. If neither of these is available, submerge the tooth in cool water. Go to the dentist immediately or the nearest children’s emergency room. Time is important for saving the tooth, rectifying the situation in 30 minutes or less is ideal.
For primary (baby) teeth – Teeth are not re-implanted. The tooth fairy will be at work prematurely.
