Schneidezähne

Schneidezähne are the teeth located at the front of the mouth, used for cutting and biting. In humans, there are typically eight incisors, four in the upper jaw and four in the lower jaw. The central incisors are the largest and most prominent, followed by the lateral incisors. These teeth have a sharp, chisel-like edge, which is ideal for their primary function of severing food into smaller pieces.

The structure of an incisor consists of a crown, which is the visible part above the gumline, and a root, which anchors the tooth in the jawbone. The crown is covered by enamel, the hardest substance in the human body, protecting the underlying dentin and pulp. The pulp contains nerves and blood vessels that nourish the tooth.

In many mammals, incisors are highly specialized. For example, rodents have continuously growing incisors that are kept sharp by gnawing. Elephants have incisors that are modified into tusks, used for defense and foraging. The shape and size of Schneidezähne can vary significantly across different species, reflecting their dietary adaptations and evolutionary history.

The development of incisors begins during fetal development, with the tooth buds forming in the jaw. They erupt into the mouth at different times during childhood and adolescence. Maintaining good oral hygiene, including regular brushing and flossing, is crucial for the health of Schneidezähne, preventing decay and gum disease.
