You inherited your bones, not your jaw. The lower face responds to load the same way any other muscle does, and modern food removed the load. Put it back.
Load the jaw daily
Raw carrot, celery, jerky, hard cheese, chicken on the bone, apple with the skin, dense sourdough. Ten to fifteen minutes of proper chewing at each main meal is a session your face never signed up to skip.
Chew both sides equally. One-sided chewing builds asymmetry into your face over years. Alternate deliberately for a week; it becomes automatic.
Second-line tool
Mastic or an equivalent hard gum, 10–15 minutes a day, is a real dose. Not a shortcut for eating right. Skip if you have any jaw pain because loading an inflamed joint makes it worse.
The other half
A trained jaw that always hangs open builds no resting tone. Tongue on the roof, lips closed, breath through the nose. That posture is what pulls the mid-face forward over months.
