Clean the area around the sore tooth thoroughly. Rinse the mouth vigorously with warm salt water or use dental floss to dislodge trapped food or debris. DO NOT place aspirin on the gum or on the aching tooth. If face is swollen, apply a cold compress. Take acetaminophen or ibuprofen for pain. See a dentist as soon as possible.
Apply ice to bruised areas. If there is bleeding, apply firm but gentle pressure with a clean gauze or cloth. If bleeding does not stop after 15 minutes or cannot be controlled by simple pressure, take the child to a hospital emergency room.
Find the tooth. Handle the tooth by the top (crown), not the root portion. You may rinse the tooth, but DO NOT clean or handle the tooth unnecessarily. Try to reinsert it in its socket. Have the child hold the tooth in place by biting on a gauze or cloth. If you cannot reinsert the tooth, transport the tooth in a cup containing milk. See a dentist IMMEDIATELY! 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 dental wax, cotton balls, gauze or chewing gum. If a wire is stuck in the gums, cheeks, or tongue, DO NOT remove it. Take the child to a dentist immediately. Loose or broken appliances which do not bother the child do not usually require emergency attention.
Rinse dirt from injured area with warm water. Place cold compresses over the face in the area of the injury. Locate and save any broken tooth fragments. Immediate dental attention may be necessary.
