Different Kinds Of Teeth. Your teeth look different from one another because they are designed to do different things. The Incisors are the teeth in the very front. Theyâre the sharpest teeth, built to cut food and shaped to shovel the food inward. The Canine teeth are in the corners of your mouth. Because theyâre meant for grasping and tearing food, they have very long roots. Premolars are located just behind your Canine teeth. Premolars have a more flat chewing surface because theyâre meant for crushing food. The Molars are the last teeth towards the back of your mouth. Molars are much bigger than the Premolars and have bigger, flatter chewing surfaces because their job is to chew and grind the food into smaller pieces.
