MeSH Cuspid

In mammalian oral anatomy, the canine teeth, also called cuspids, dogteeth, fangs, or (in the case of those of the upper jaw) eye teeth, are relatively long, pointed teeth. However, they can appear more flattened, causing them to resemble incisors and leading them to be called incisiform. They evolved and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in the mammalian mouth. Most species that develop them normally have four per individual, two in the upper jaw and two in the lower, separated within each jaw by its incisors; humans and dogs are examples. In most animals, canines are the anterior-most teeth in the maxillary bone. It is a common fallacy to describe canine teeth as being the hallmark of a carnivorous diet - the teeth associated with carnivory are the carnassial teeth.

Details

There are four Canine Teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to each lateral incisor. They are larger and stronger than the incisors, and their roots sink deeply into the bones, and cause well-marked prominences upon the surface. The term lateral can refer to: an anatomical definition of direction. ... Incisors are the first kind of tooth in heterodont mammals. ...


The crown is large and conical, very convex on its labial surface, a little hollowed and uneven on its lingual surface, and tapering to a blunted point or cusp, which projects beyond the level of the other teeth. The root is single, but longer and thicker than that of the incisors, conical in form, compressed laterally, and marked by a slight groove on each side. Labials are consonants articulated either with both lips (bilabial articulation) or with the lower lip and the upper teeth (labiodental articulation). ... Many animals have longer and more flexible tongues than humans. ...


The upper canine teeth (popularly called eye teeth) are larger and longer than the lower, and usually present a distinct basal ridge. The name "eyeteeth" derives from a superstition that the roots of the canines are involved with the eyes in such a way that loss of the eyeteeth can cause blindness. The expression of giving one's eyeteeth for something refers to this superstition and to the importance of these teeth in the dentition.


The lower canine teeth (popularly called stomach teeth) are placed nearer the middle line than the upper, so that their summits correspond to the intervals between the upper canines and the lateral incisors.
