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