Emergency Department Care

Provide adequate pain management, tetanus vaccination, and ensure proper follow-up care.[9, 10, 12, 13]



Consult a dental or oral maxillofacial surgeon for splinting.

Subluxation or extrusion injury

A dentist should adjust and splint.[14]

Intrusion injury

A tooth should be allowed to re-erupt. Dentoalveolar ankylosis of a primary tooth hinders eruption of the succedaneous permanent tooth.

  • Intruded primary teeth: Allow teeth to re-erupt before possible repositioning.
  • Intruded adult teeth: Allow re-eruption then stabilize.

Surgical Care

A study investigated differences in the periodontal outcomes of palatally displaced canines (PDC) exposed with either an open or a closed surgical technique. The study concluded that there is a periodontal impact when a unilateral PDC is exposed and aligned, however, this impact is small and unlikely to have clinical relevance in the short term.[15]
