The maxillary teeth in frogs are the teeth found on the upper edge of the animal's jaw, forming a ridge of small cone teeth around it. Frogs use this set of teeth to hold their prey.
Most frogs have teeth, and those that do only have them on their upper jaws and the upper part of their mouths. This is not a problem as frogs don't chew their food. Also, according to PawNation, "Frogs, for the most part, don't employ their teeth for self-protection, so biting isn't usually a big concern." The other set of teeth that frogs have are located on the roofs of their mouths. These are known as vomerine teeth, which are also used for holding prey.
