Chewing  leads to smaller particles for swallowing, and more exposed surface area for digestive enzymes to act on.
In other words, it means the extraction of more fuel and raw materials from a mouthful of food.
This is especially important for mammals because they heat their bodies from within.
Chewing gives mammals the energy needed to be active not only during the day but also the cool night, and to live in colder climates or places with changing temperatures.

It allows them to sustain higher levels of activity and travel speeds to cover larger distances, avoid predators, capture prey, and make and care for their young.

Mammals are able to live in an incredible variety of habitats, from Arctic tundra to Antarctic pack ice, (from) deep open waters to high- altitude mountaintops, and (from) rainforests to deserts, in no small measure because of their teeth.
