Mandibular lateral incisor

Study entry

Location

Socket of the alveolar part of the mandible, between the central incisor and the canine.

Structure

Very similar to the central, but a little larger and with the incisal edge sloping distally. One flattened root, with one or two canals. It erupts at about 8 to 9 years.

Neighborhood

It lies between the central incisor and the canine.

Blood supply

Inferior alveolar artery, branch of the maxillary, which runs in the mandibular canal and gives a branch to each root; the veins accompany the artery.

Innervation

Inferior dental plexus, formed by the inferior alveolar nerve (CN V3), which runs in the mandibular canal.

Lymphatics

They drain into the submental and submandibular lymph nodes.

Clinical

It is subject to crowding of the anterior teeth for lack of space and, like the central, to accumulation of calculus on the lingual surface.
