What is the primary function of incisors?

Incisors are primarily designed for cutting food. Their sharp, flat edges are perfectly suited for slicing through food items, such as fruits and vegetables, as well as for biting off pieces of other types of food. This function is crucial in the early stages of digestion, where the mechanical breakdown of food begins. While other types of teeth serve different purposes—such as molars for grinding and canines for ripping—the distinctive shape and positioning of incisors make them the leading teeth for cutting. Hence, their role is essential in both feeding and the overall process of eating.
