What makes a Diprotodontia a Diprotodontia?

Why do Diprotodontia have no canine teeth?
Diprotodontia also do not have canine teeth, instead have an empty space where these teeth should be. This unique dental pattern can be explained by the diet that these animals have. Diprotodonts are herbivores, so the sharp front teeth are used for cutting up pieces of grass and leaves to be eaten.
