What is an "incisor"?
An incisor is a sharp, chisel-shaped tooth located at the front of the human mouth, either in the upper or lower jaw. It is designed for cutting and biting into food. Typically, adults have four incisors, two central incisors, and two lateral incisors. The incisor has a flat surface and a thin edge, allowing for effective slicing and shearing of food. It plays a crucial role in the initial stages of chewing and is visible when a person smiles. The incisor also contributes to the clarity of speech by aiding in the pronunciation of certain sounds.
