Begin by cleaning around the sore tooth meticulously. Using warm salt water, rinse the mouth to displace any food trapped between teeth. UNDER NO CIRCUMSTANCES should you use aspirin on the aching tooth or on the gum. In the event of facial swelling, apply a cold compress to the area. For temporary pain relief, acetaminophen is recommended. See a dentist as soon as possible.

Ice can be applied to any bruised areas. For bleeding, apply firm (but gentle) pressure with sterile gauze or a clean cloth. If the bleeding does not stop with pressure or continues after 15 minutes, go to an emergency room.

Remove a broken appliance only if it comes out easily. If it is lodged or painful to remove, cover any protruding edges with wax, cotton balls, gauze or chewing gum. DO NOT REMOVE any wire caught in the gums, cheek or tongue; see a dentist immediately. Emergency attention is usually not required for loose or broken appliances that cause no discomfort.

Rinse the area with warm water. Put a cold compress over the facial area of the injury. Recover any broken tooth fragments. Get immediate dental attention.

Recover the tooth, making sure to hold it by the crown (top) and not the root end. Rinse, but do not clean or handle the tooth more than necessary. Reinsert the tooth in the socket and hold it in place using a clean piece of gauze or cloth. If the tooth cannot be reinserted, carry it in a cup containing milk or water. Because time is essential, see a dentist immediately.

In the event of jaw injury, tie the mouth closed with a towel, tie or handkerchief. Go immediately to an emergency room.

Fold a piece of gauze and place it (tightly) over the bleeding area. Bite down on the gauze for 15 minutes; if bleeding continues, see a dentist.

Over-the-counter medications will usually provide temporary relief. If sores persist, visit your dentist.
