Brief Description: This is a hands-on lesson studying the four types of teeth and the job of each type. Several small groups will work together to act out the role of each type of tooth. Grade Level: 1st. Background Information: The four types of teeth are the incisors, cuspids, bicuspids, and molars. Each type of tooth has its own job. The incisors, located in the center and front of the mouth, are used to cut (incise) food. There are eight incisors, four in the upper jaw and four in the lower jaw.
Human tooth. For other uses of tooth or teeth, see Tooth (disambiguation). The human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digestion. Humans have four types of teeth: incisors, canines, premolars, and molars, each with a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums.
