The Role of the Masseter Muscle in TMJ Movement
The masseter muscle is one of the primary muscles involved in TMJ movement, responsible for closing the jaw during chewing. It spans from the cheekbone to the lower jaw and provides the strength needed for biting down. This powerful muscle works alongside the temporalis and pterygoid muscles to ensure smooth jaw motion. When trigger points develop in the masseter, pain can radiate to the ear, teeth, and even the temple. This referral pattern often leads to misdiagnoses, such as ear infections or toothaches. Addressing trigger points through massage or physical therapy can alleviate these symptoms and improve TMJ function.
