Remain calm. Locate the tooth and pick it up by the chewing surface, being careful not to touch the root. If the tooth is not dirty or broken, you should attempt to reinsert it into your child’s mouth into the empty socket. If you are able to reinsert it, have your child hold the tooth in place by biting on a clean piece of cloth or gauze and go directly to your dentist. If you cannot reinsert the tooth (or if it is dirty or broken), put the tooth in a glass of milk, saliva, saline (salt) solution or an emergency tooth preservation kit and take it and your child immediately to your dentist’s office. It is best to see a dentist with 30 minutes.
