Most of us chew our food without ever thinking about the complex processes required to perform this vital action. It may seem a simple task to raise and lower our jaw, but the process of mastication (chewing) requires several components to work together: nerves, muscles, joints, bones, and teeth. A problem with any one component can lead to real medical issues like TMD (temporomandibular joint disorder), which causes chronic pain and other symptoms.
Mastication Mechanics
In order to raise the lower jaw (mandible) into contact with the upper dental arch (maxilla), your brain sends a signal to a collection of four muscles, the tensor tympani, tensor veli palatini, mylohyoid, and the digastric. These muscles pull the mandible up and back, flexing the temporomandibular joint, often called the TMJ. Continue reading ‘The Science Behind the Bite’ »
