Uncommon card · No. 106472

Mewing is an unproven form of oral posture training purported to improve jaw and facial structure. It was named after British orthodontist John Mew, who created the technique as a part of a practice called "orthotropics", together with his son Mike. It involves placing one's tongue at the roof of the mouth and applying pressure, purportedly to modify the structure of the jaws.
