When the middle labial lobe is missing the mesial and distal labial lobes will bend on each other creating what is called "peg shaped laterals". Treatment usually include buildup by composite or a fixed crown restoration. The upper laterals are the 2nd most varied teeth, after the 3rd molars. They can be peg shaped, twisted crown and roots, and sometimes missing.

Compared to the maxillary central incisor, the maxillary lateral incisor has more rounded mesial and distal incisal angles. The distal outline is always more rounded. The root is often tapered distally, often with a sharp curve distally and to an apex; however, the curve can be absent. The mesial and

The permanent tooth typically will erupt between when the child is 8 or 9 years old, while the root will continue to mineralize until around 11 years old. The tooth's crown will conclude its development around the age of 4 or 5. The upper lateral incisor is made of 4 lobes of calcification (3 labial

There are two maxillary lateral incisors in the deciduous dentition. The teeth have a more curved distoincisal angle than the primary maxillary central incisor. The tooth is longer cervicoincisally than it is mesiodistally. The average length of the primary lateral incisor is 15.8 mm, with the

Compared to the tooth's mesial view of the cervical line, the distal cervical line is slightly more cervical by close to a millimeter. There may be a developmental groove present for all or most of the length. The distal view of the lateral incisor fits into the geometric shape of a triangle.
