Some people start the New Year off with a few poxy resolutions scribbled down somewhere only to be forgotten by February. Me? I’m going on a two-week juice fast.
Day 8: The Daily Grind
An interesting thing happens when you stop using your mouth to chew. You begin to notice just how often you use your jaw muscles. Every time you take a bite of food, your mandible contracts, retracts and moves side-to-side. It’s an incredibly complex ballet of two coordinated joints, requiring eight muscles that extend from the base of the jaw to the sides of the skull well above the brow ridge and temple. These same muscles are used when talking, grinning, protruding the jaw. They are among the tightest muscles in the body.
For me, clenching the jaw is an immediate response to stress. I also tend to clench my jaw or grind my teeth when I sleep. Every time the upper and lower teeth are in contact with each other I know I’m flexing some kind of muscle. Now that I’ve been chew-free for more than a week, I can tell you that it happens way more often than I ever realized. I can also tell you it’s taking a bigger toll than you might suspect.
