In 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, evolved (and used, in most species where they remain prominent) primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in the 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.
