What do frogs have in their mouth that toads don't?

Nearly all species of frogs have several types of teeth on their upper jaws, while no species of toad has teeth. The two types of teeth frogs have are called vomerine teeth and maxillary teeth. Frogs continue to shed and regrow their teeth throughout their entire lives.

Vomerine teeth are small and conical, appearing in pairs, while maxillary teeth are smaller and are not visible without dissection. A frog's teeth help it trap its prey until it is ready to eat it; they are not used to chew. While a frog's teeth help it hunt in the water, sometimes even preying on fish, toads tend to stick to dry land where they don't have any trouble holding onto their prey.
