Humans have four different types of teeth: incisors, canines, premolars, and molars. Our incisors are the four front teeth that have a wide and flat shape. The purpose of these four front teeth is solely for cutting through food that we eat. Our canines are the teeth on each side of the incisors and have a very pointy sharp shape. We have two on the bottom of the jaw and two on the top. These four teeth help tear up tougher food that the incisors can’t tear. Humans today have 8 premolars; their shape is wide, with ridges and depressions. The function of our molars is to crush and grind food into small pieces to prepare for food digestion. Lastly, there are 8 molars in mouths today as well, which also shares the same purpose as premolars.
