 What type of teeth do non-mammalian and mammalian vertebrates possess? How is the acquisition of adult teeth in each of these groups different?

Mammals: heterodont teeth, incisors (nip food), canines (piercing and holding instruments), premolars & molars (chewing), and carnassials (cut and shear meat and tendons, crack bones); Diphydont tooth replacement (Incisors, canines, and premolars erupt as the deciduous teeth (milk teeth, or baby teeth) in juvenile mammals. These teeth fall out and are replaced by a permanent set of teeth consisting of the same number of incisors, canines, and premolars. Molars now erupt and become part of the permanent set)

Nonmammals: polyphyodont tooth replacement
