Key Features & Anatomical Relations

The maxillary canine tooth is the single canine tooth that is found in a quadrant of the maxillary dental arcade. It includes the following bony features:

- parts: crown, root, and cervical line;

- surfaces: incisal margin, and labial, lingual, mesial, and distal surfaces;

- landmarks: cusp, cingulum, marginal ridges, lingual fossae, and lingual ridge.

The maxillary canine tooth is located:

- distal to the maxillary lateral incisor tooth;

- mesial to the maxillary first premolar tooth.

The root of the maxillary canine tooth is lodged in a dental alveolus of the maxilla.

Development

The deciduous maxillary canine tooth undergoes calcification during the seventeenth week in utero, with the development of the crown being completed during the ninth month after birth. Eruption of this tooth occurs during the nineteenth month after birth and the development of the root is completed during the fourth year.

The permanent maxillary canine tooth undergoes calcification during the fourth to fifth months after birth, with the development of the crown being completed during the sixth to seventh years. Eruption of this tooth occurs during the eleventh to twelfth years and the development of the root is completed during the thirteenth to fifteenth years (Nelson, 2014).

Function

As with all canines, the maxillary canine tooth is sharp and pointed and specializes in the gripping (prehension) and tearing of food during mastication.

The tips of the maxillary canines are in a plane related to the middle of the incisive papilla in 92% of cases,37 which usually positions them closer to the residual ridge compared with the maxillary anterior incisors.
