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.
