What Does the Masseter Muscle Do?
The masseter helps with chewing food, closing the jaw, applying force during biting, assisting certain movements of the mandible and supporting efficient food grinding.
Why Is the Masseter Considered So Strong?
The masseter helps generate substantial force during jaw closure. Its short, thick muscle fibres are well suited for producing force. The jaw acts as a lever system that allows the muscle to give considerable pressure during biting.
