Incisors are the front four teeth in the upper and lower jaw, situated in between the cuspids. Generally incisors have one root.
The first two front teeth known as central incisors, erupt sometime between the age of six and seven. Lateral incisors are found next to the centrals and appear around the age of seven or eight.
The incisors primary function is to cut and tear into food, although the esthetic appearance of these anterior teeth is highly scrutinized as they are visible during smiling, eating, and talking.
