Both the maxillary and mandibular canines are called the "cornerstone" of the mouth because they are all located three teeth away from the midline, and separate the premolars from the incisors.

The location of the canines reflect their dual function as they complement both the premolars and incisors during mastication, commonly known as chewing.

There is a single cusp on canines, and they resemble the prehensile teeth found in carnivorous animals.

In the universal system of notation, the deciduous mandibular canines are designated by a letter written in uppercase.

The international notation has a different numbering system than the previous two, and the right permanent mandibular canine is known as "43", and the left one is known as "33".
