Sign in to saveAlso known as incisors
Incisors (from Latin incidere, "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom). Opossums have 18, whereas armadillos, anteaters and other animals in the superorder Xenarthra have none.
Incisors are the front teeth found in most mammals, with humans having eight of them (two on each side of the upper and lower jaw). They vary significantly across species—opossums have 18, while armadillos and anteaters have none at all.

Incisors (from Latin incidere, "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom). Opossums have 18, whereas armadillos, anteaters and other animals in the superorder Xenarthra have none.
==Structure== Adult humans normally have eight incisors, two of each type. The types of incisors are: maxillary central incisor (upper jaw, closest to the center of the lips) maxillary lateral incisor (upper jaw, beside the maxillary central incisor) mandibular central incisor (lower jaw, closest to the center of the lips) mandibular lateral incisor (lower jaw, beside the mandibular central incisor)
