Some species have teeth that are all of the same type, such as most non-mammalian vertebrates - homodont dentition. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed polyphyodont. Species whose teeth differ morphologically are said to have heterodont dentition. The dentition of animals with only one set of teeth throughout life is monophyodont.
The dentition of animals (including humans) with two successions of teeth (deciduous, permanent) is referred to as diphyodont.

A diphyodont is any animal with two successive sets of teeth, initially the "deciduous" set and consecutively the "permanent" set. Most mammals are diphyodonts as to chew their food they need a strong, durable and complete set of teeth. In diphyodonts the number of teeth that are replaced varies from species to species but in humans a set of twenty deciduous teeth are replaced by a completely new set of thirty-two adult teeth.
