Injuries to Primary Teeth

The greatest incidence of trauma to theprimary dentition occurs at 2 to 3 years of age, when motor coordinationis developing. The most frequently injured teeth are the maxillaryincisors.

Injuries to primary teeth include fracture, displacement,and avulsion.

Injury to Primary Incisor
Small fractures of primary teeth may leavea roughened tooth surface and may require smoothing. If the fractureexposes the pulp, pulp (or endodontic) treatment and stainless steelcrown (SSC) maybe required for restoring the fractured tooth.Tooth fractures must be assessed radiographically to determine if rootfractures are present.
Fractured Primary Tooth
Displacement injuries need to be evaluatedto determine the child’s occlusion and the proximity of the injuredprimary tooth to the developing permanent tooth. An extruded primarytooth that interferes with a child’s ability to bite (or occlude) shouldbe repositioned or extracted. An intruded tooth not contactingthe permanent tooth bud may be allowed to re-erupt. Immediateextraction may be indicated if the radiograph reveals that the intrudedtooth contacts the permanent tooth bud. Periodic reevaluationof the intruded tooth is prudent.
