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.
What is the Total Number of Teeth in the Mouth? An adult person who has all his or her adult teeth should have a total of 32 teeth. These include 8 incisor teeth (four upper and four lower), 4 canine teeth (two upper and two lower), 8 premolars (four upper and four lower), and 12 molars (six upper and six lower). The 4 wisdom teeth are among the molars. A child, who is younger than 6 years old, usually has 20 deciduous teeth. These include 8 primary incisor teeth (four upper and four lower), 4 primary canine teeth (two upper and two lower) and 8 primary molars (four upper and four lower).
