Mouth breathing is far more than a habit—it’s a developmental force.
Every breath taken through the mouth alters tongue posture, jaw position, and the balance of forces that shape the face.
Over time, this can narrow dental arches, elongate the face, and even influence brain development by affecting sleep quality and oxygen delivery.
It’s not cosmetic. It’s structural—and it’s happening right now, every time a child breathes through their mouth.
