Polyphyodont

A polyphyodont is any animal whose teeth are continually replaced. In contrast, diphyodonts are characterized by having only two successive sets of teeth.^[1]

Polyphyodonts include most toothed fishes (most notably sharks), many reptiles such as crocodiles and geckos,^[2]^[3]^[4] and most other vertebrates, with mammals being the main exception (though not absolute).
