A toothache usually indicates that a cavity or fracture has gotten sufficiently deep to involve the nerve in the center of the tooth. If this is the case, root canal therapy is generally necessary. Avoid placing an aspirin between your tooth and gum to relieve pain, because the dissolving aspirin can actually harm your gum tissue.
Broken, Fractured, or Displaced Tooth
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 locate 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.
For a fractured tooth, it is best to rinse with warm water and again, apply a cold pack or compress. Ibuprofen may be used to help keep down swelling.
If the tooth fracture is minor, the tooth can be sanded or if necessary, restored by the dentist if the pulp is not severely damaged.
