Right Upper Lateral Secondary Incisor Tooth (Dens incisivus lateralis maxillaris dexter)
Educational content only — not medical advice.
Anatomy
The right upper lateral secondary incisor tooth (FDI #12, Universal #7) is situated between the central incisor and canine in the maxillary dental arch. Characterized by a narrower crown than the central incisor, more rounded incisal angles, and a single root often exhibiting a slight distal apical curve, it assists in shearing food and completing the aesthetic arch curvature.
Clinical notes
The maxillary lateral incisor shows the highest rate of developmental anomalies after third molars, including congenital absence (agenesis), microdontia (peg lateral), and palatogingival grooves predisposing to localized periodontitis.
