In real life insectivores have very small teeth, as insects are small and don't need chewing. Rangatora would have larger teeth as branaba have hard exoskeletons that need to be destroyed. As the shell is quite hard and stiff, punching it with teeth like that would get insect shell all around its teeth. Crushing wedge teeth would be better for destroying the insect, presuming he eats the shell as well.
