The first step in assessing dentition is to determine whether the patient has primary or permanent dentition, or both. Primary teeth are more milky-white in color with a smooth incisor edge. It is very uncommon for children aged < 5 years to have permanent teeth.
Assess each tooth for: (1) fracture, (2) pulp exposure, (3) an empty socket, (4) displacement, (5) mobility, and (6) percussion tenderness.
If there are missing teeth or tooth fragments, consider ordering radiographs to rule out aspiration or foreign body displacement.
If there is clinical concern for an alveolar bone fracture (mobility and dislocation of multiple continuous teeth), order dental radiographs. If panoramic x-ray is unavailable, consider a maxillofacial CT scan.
