What are incisors primarily used for?

Incisors are primarily used for biting food. These teeth are flat and sharp, which makes them ideal for cutting through food items, especially soft foods like fruits and vegetables. Their primary function is to grasp and shear food as the first step in the digestion process. This action is crucial because it breaks down food into smaller pieces that can be further processed by the molars, which are more suited for grinding and crushing. The design and positioning of incisors in the front of the mouth facilitate this biting action effectively.
