Dental avulsion

Revision as of 15:42, 9 February 2015 by Rossdonaldson1 (talk | contribs) (Management)


  • Dental emergency
  • Tooth is completely removed from its socket
  • Often associated with alveolar ridge fracture


  • Where is the tooth?
    • It may be intruded, aspirated, swallowed, or embedded in the oral mucosa
    • Consider facial films, CXR
  • Additional Injuries?
  • Age and head bleed risk?

Differential Diagnosis

Dentoalveolar Injuries

Odontogenic Infections




  • Replace avulsed tooth as soon as possible (as long as no alveolar ridge fx, no severe socket injury)
    • If reimplanted within 1hr 66% chance of good outcome
    • Rinse (no scrubing!) tooth in saline, suction socket (if necessary), reimplant tooth, bond tooth to neighboring teeth
    • Manipulate tooth only by the crown
  • Storage solution (in order of efficacy): Hank's balanced salt solution > Milk > saliva > saline
  • Penicillin or clindamycin


  • Do not re-implant primary teeth
    • Increased risk of interference with the eruption of the permanent tooth[1]
  • Refer to pedodontist for space maintainer
