What animals have acrodont teeth?
Tuataras, chameleons, and agamid lizards, like water dragons and bearded dragons, are the only species that have true acrodont dentition (Klaphake 2015, Mehler 2003, Edmund 1970). Acrodont teeth are weakly attached and lost relatively easily while feeding or capturing prey (Klaphake 2015, O’Malley 2005, Edmund 1970).
Are mammalian teeth acrodont?

What reptiles have acrodont teeth?
Chameleons and agamid lizards, such as bearded dragons and water dragons, possess acrodont dentition. Acrodont teeth are easily lost and are not replaced. Instead as teeth wear, the biting surface eventually becomes the bone itself.
Which animal has premolar teeth?
All horses have twelve premolars, twelve molars, and twelve incisors. Generally, all male equines also have four canine teeth (called tushes) between the molars and incisors.
