Find the tooth. You may rinse the tooth, but DO NOT clean or handle the tooth unnecessarily. Try to reinsert it in the socket. Have the child hold the tooth in place by biting on a clean gauze or cloth. If you cannot reinsert the tooth, transport the tooth in a cup containing milk or water.
Time is a critical factor in saving the tooth.
If a broken appliance can be removed easily , take it out. If it cannot, cover the sharp or protruding portion with cotton balls, gauze, or chewing gum. If a wire is stuck in the gums, cheek, or tongue, DO NOT remove it. Take the child to a dentist immediately. Loose or broken appliances which do not bother the child don't usually require emergency attention.
