The maxillary central incisor is a human tooth in the front upper jaw or maxilla and is usually the most visible of all teeth in the mouth. It is located mesial (closer to the midline of the face) to the maxillary lateral incisor. As with all incisors their function is for shearing or cutting food during mastication (chewing). There is typically a single cusp on each tooth called an incisal ridge or incisal edge.
