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.
A full complement of teeth is 8 incisors, 4 canines, 8 premolars and 12 molars divided equally between the upper and lower jaws and totaling 32 teeth. Three molars occupy the back of your left and right sides, the last one of which is termed the third molar or wisdom tooth. This is usually the last tooth to erupt.
