Breath

Exactly a year to the week after I began wearing Belfor’s retainer, I visited a private radiology clinic in downtown San Francisco and had my airways, sinuses, and mouth rescanned. Belfor sent the results to AnalyzeDirect at the Mayo Clinic to study what had happened to my face and airways.

Today, the official website of the U.S. National Institutes of Health attributes the causes of crooked teeth and other deformations of the airway “most often to heredity.” Other causes include thumb-sucking, injury, or “tumors of the mouth and jaw.”
There is no mention of chewing; no mention of food at all.

The exercise, which Mike’s hordes of social media fans call “mewing,” has been popularly adopted as “a new health craze.” After a few months, mewers have claimed their mouths expanded, jaws became more defined, sleep apnea symptoms lessened, and breathing became easier. Mike’s own instructional video on mewing has been viewed a million times.
