Under the nose and above the chin is where the teeth are found, but what else do you know about these things that you have at some stage of your life? Some answers on common teeth questions will be discussed here. There is a function that comes with each type of teeth. Front teeth are also called, incisors. Not only the sharpest, these are also used to shovel food in. What you find near the corner of your mouth are what you call canine teeth. When it comes to tearing or grasping food, these teeth with long roots function well. The teeth behind the premolars with flat surfaces for crushing food are called premolars. In contrast to premolars, the molars have bigger and flatter surfaces and sizes than them. These are the ones that grind food into very small bits.
