What do human incisors look like?
Human incisors have thin, blade-like crowns that are adapted for the cutting and shearing of food preparatory to grinding.
Viewed mesially or distally, the crowns of the incisors are roughly triangular in shape, with the apex of the triangular at the incisal margin of the tooth.
This shape is thought to facilitate the penetration and cutting of food.
Viewed buccally or lingually, the incisors are trapezoidal, the shortest of the uneven sides being the base of the crown cervically.
