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.
For wisdom teeth removal surgery see: Impacted wisdom teeth. A wisdom tooth or third molar is one of the three molars per quadrant of the human dentition. It is the most posterior of the three. Wisdom teeth generally erupt between the ages of 17 and 25. Most adults have four wisdom teeth, one in each of the four quadrants, but it is possible to have fewer or more, in which case the extras are called supernumerary teeth.
