Canines are pointed teeth located between the incisors and premolars in the mouth. They are typically sharper and longer than other types of teeth, designed for tearing food. Humans usually have four canines, two on the top and two on the bottom, which play a crucial role in biting and chewing. In many animals, such as dogs and cats, canines are more pronounced and serve important functions for hunting and defense. These teeth are essential for gripping and tearing flesh, reflecting the animal's diet and lifestyle. Canines are also a key feature in the dental structure of various species.
