Eckzähne

Eckzähne, also known as canines or cuspids, are a type of tooth found in humans and many other mammals. They are located between the incisors and the premolars, typically one on each side of the jaw in both the upper and lower arches, for a total of four. In humans, the permanent adult dentition includes four incisors, four premolars, eight molars, and four canines.

The primary function of canines is to grip and tear food. Their pointed shape and strong roots are well-suited for this purpose. In some animals, such as dogs and cats, the canine teeth are particularly prominent and are used for defense, hunting, and tearing flesh. In humans, while still serving their digestive function, they are less pronounced than in many carnivores.

The development of canine teeth begins before birth, with the tooth germ forming in the jaw. They erupt into the mouth at different times depending on whether they are deciduous (baby) teeth or permanent teeth. The deciduous canines typically emerge around 16 to 20 months of age, while the permanent canines usually erupt between 9 and 13 years of age. The upper canines tend to erupt slightly later than the lower ones. The unique shape and position of canine teeth also contribute to the overall structure and appearance of the face.
