Dental systems are of two types - homodont and heterodont, which in turn are classified into monophyodont and diphyodont. With homodont dental system all teeth have the same shape throughout the range, for example, like have fishes, while humans and other primates have a heterodont system with different shapes and functions of teeth. Diphyodont dental sustem implies teeth shift, and monophyodont system means a life with one set. In minority is polyphyodont whose teeth are able to regenerate.
