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 for pain and see a dentist as soon as possible.
Apply ice to bruised areas. If 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 by 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 clean gauze or cloth. If you cannot reinsert the tooth, transport the tooth in a cup containing milk or water. See a dentist IMMEDIATELY. Time is a critical factor in saving the tooth.
Rinse dirt from injured area with warm water. Place cold compresses over the face in the area of injury. Locate and save any broken tooth fragments. Immediate dental attention is necessary.
If a fractured jaw is suspected, try to keep the jaws from moving by using a towel, tie, or handkerchief, then take the child to the nearest hospital emergency room.
Fold and pack a clean gauze or cloth over the bleeding area. Have the child bite on the gauze with pressure for 15 minutes. This may be repeated once; if bleeding persists, see a dentist.
Many children occasionally suffer from “cold” or “canker” sores. Usually over-the-counter preparations give relief. Because some serious diseases may begin as sores, it is important to have a dental evaluation if these sores persist.
