Animals where this occurs include antelopes, musk-deer, camels, horses, wild boar, some apes, seals, narwhal, and walrus. [6] Male dogs have larger canines with different contour than do females. [7] Humans have the proportionately smallest male canine teeth among all anthropoids and exhibit relatively little sexual dimorphism in canine tooth size.
The canine teeth are able to withstand the tremendous lateral pressures from chewing. There is a single cusp on canines, and they resemble the prehensile teeth found in carnivorous animals. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular canine and that of the permanent mandibular canine.
This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .
Canine space infections may occur by spread of infection from the buccal space. [2] Signs and symptoms of a canine space abscess might include swelling that obliterates the nasolabial fold . If left untreated, infections of this space will eventually spontaneously drain via the medial or lateral canthus of the eye, as this is the path of least ...

There are two main theories on the aetiology of palatally impacted canines. One is the genetic theory whereby the cause is thought to be polygenic. There is a high rate of incidence of ectopic canines with dental anomalies such as pegged lateral incisors, missing lateral incisors, delayed eruption, and the absence of crowding.
Permanent teeth will start coming in around 12–16 weeks, and puppies will eventually end up with 42 permanent teeth. The process of teething is painful to puppies much like babies. During this process puppies will experience increased salivation, loss of appetite, and extreme irritability when the teeth do erupt from the gums.
Generalized bone loss occurs most frequently as horizontal bone loss. [2] Horizontal bone loss manifests as a somewhat even degree of bone resorption so that the height of the bone in relation to the teeth has been uniformly decreased, as indicated in the radiograph to the rig defects occur adjacent to a tooth and usually in the form of a triangular area of missing bone, known as triangulation.
