Broken, Fractured or Displaced Teeth
A broken, fractured or displaced tooth is usually not a cause for alarm as long as decisive, quick action is taken. If the tooth has been knocked out, try to place the tooth back in its socket while waiting to see your dentist. First, rinse the mouth of any blood or other debris and place a cold cloth or compress on the cheek near the injury. This will keep down swelling.
If you cannot place the tooth back in its socket, hold the dislocated tooth by the crown—not the root. Next, place it in a container of warm milk, saline or the victim's own saliva and keep it in the solution until you arrive at the emergency room or dentist's office.
