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.
Based on the kinds of teeth found there are two types of dentition: Homodont dentition is found in the majority of vertebrates such as fish, amphibia and reptiles in which all teeth are functionally and anatomically of the same type, although their size may be variable depending on the location.ased on the type of attachment of teeth on the jaw bone the following three types are found in vertebrates: Acrodont teeth are attached on the top surface of the jaw bone as in fish and amphibians. This type of attachment is not very strong and teeth are lost easily and are replaced by new ones.
