2.  Mastication: Humans have different types of tooth each having typical appearance and performing particular function. The Incisors arranged in the anterior part of the oral cavity help to incise the food. They are flat and sharp. Canine are the teeth which present at each corner of mouth help in shearing the food. Next to the Canines the Premolars which have broader grinding surface and play a major role in grinding and chewing the food. The molars are large teeth arranged at the back of the oral cavity having a large grinding surface mainly to grind the food.
