Dental injury facts

  • A minor broken tooth (fracture) involves chipping of the enamel only.
  • A deeper fracture can involve both the enamel and the dentin of a tooth.
  • Death of pulp tissue can lead to serious tooth infection and abscess.
  • A serious fracture that exposes both the dentin and the pulp tissue should be treated promptly.
  • The most important variable affecting the success of reimplantation of a tooth that is knocked out is the amount of time that the tooth is out of its socket.
  • Care should be taken to handle the knocked-out tooth only by its crown and not by its root.
  • Prevention of dental injuries involves aligning protruding front teeth by dental braces and using face masks and mouthguards while participating in sports.


Trauma to the face or teeth can be caused by auto accidents, falls, and injury from sports such as football, hockey, soccer, volleyball, basketball, and baseball, etc. Patients suffering significant head, neck, or facial trauma should be evaluated and treated in hospital emergency rooms. Such trauma may involve bleeding from the nose or ears, concussion, dizziness, lapse of memory, disorientation, severe headache and earache, or breaking (fracture) of the skull and/or jaws. Most hospitals have on their staff oral surgeons who can treat fractures of the upper or lower jaw and perform emergency tooth removal (dental extractions) and reconstruction of the dental arches.

Wear and tear due to cavities and chewing hard objects, such as pencils, ice cubes, nuts, and hard candies, can also lead to tooth fractures. Dental injury without associated head and neck trauma can be evaluated and treated in a dental office. Such dental injuries include broken (fractured) teeth, teeth totally knocked out of the mouth, or teeth displaced by unexpected external forces. These dental accidents may be associated with swelling of the gum and oral tissue. Cold packs or ice cubes placed either inside the mouth directly above the injured tooth, or outside on the cheeks or lips, can reduce pain and swelling before the patient reaches the dentist.
