Most mammals have teeth that cannot grow back or repair when they are damaged. Mammals that gnaw on things experience a lot of wear and tear on those teeth. Eventually the teeth are so worn down they are useless, and the animal can starve. Rodents evolved to have front teeth that grow constantly. For them, gnawing on things just prevents the tooth from growing too long.
Basically. Gnawing is more of a front-tooth type of chewing, while plain chewing usually uses the back teeth.

Hermione's teeth were enlarged by Draco Malfoy.
Yes, gorillas have large front teeth, particularly their canines, which are well-developed and serve multiple purposes. These teeth are primarily used for processing their plant-based diet, which includes tough leaves and stems. However, they also play a role in social interactions and displays of dominance among males. Overall, their dental structure is adapted to their herbivorous lifestyle rather than for gnawing like some other animals.
Mice show there teeth as a self defense, for protection, and for gnawing as an escape plan
