Intrusion of Permanent Teeth

Intrusion of permanent teeth, especially mature permanent teeth where the root has completed development, is the injury with the poorest prognosis.


  • Do not attempt to remove intruded tooth.
  • Refer patient to dentist immediately for evaluation and possible repositioning.

Dental Care & Expected Outcome

  • Dental care may include allowing for spontaneous eruption (preferable in immature teeth) or active repositioning (orthodontic or surgical with splinting).
  • Root canal treatment is often required, especially in mature permanent teeth.
  • Risk for complications is high and includes:
    • Tooth death
    • Root resorption
    • Tooth ankylosis
