Jaws: The Story of a Hidden Epidemic

People have some power to protect their children from this serious and cryptic environmental problem. Jaws lays out both causes and cures." Author: Gretchen C. Daily, Bing Professor of Environmental Science Source: Stanford University This manuscript looks beyond the flashy smile that so many of us pay our orthodontists for and asks the hard question: Why is it we are almost all born with the faces of angels, yet so few maintain that face value of our innate and inborn beauty? The answer revealed is intriguing, thought provoking and a much needed call to action to fight for the fullest physical potential for all our children. A must read!" Author: Simon Wong, BDSc. Source: London School of Facial Orthotropics This book is great if you’re new to the world of malocclusion and are not yet aware of the massive effect tongue ties may have on our jaws AND bodies as a whole. This epidemic has important consequences for heart health. I'm delighted Jaws is bringing it home to both citizens and health care professionals." Author: Dr. John S.

Introduction

The “cures” for the jaw epidemic are simple in outline. First, we must return childrens’ diets to much chewier foods, perhaps even supplementing them with special tough chewing gums. We must also modify some current orthodontic techniques to emphasize forward movement of both jaws and avoid extractions. All that is required is to know that jaws have continued to shrink over that past few centuries (say, 20 generations), and there is no evidence that small-jawed individuals are out-reproducing large-jawed individuals are any rate, let alone the high selection pressure that would be required to produce a discernable change in such an eyeblink of evolutionary time. Indeed, if one were to speculate on selection pressures, we think the best guess would be that, considering sleep apnea and the traumas associated with the removal of wisdom teeth, that biological selection pressures would favor larger jaws.

At the personal level, healthy jaw development will require careful and long-term cooperation of children (and parents) who have not benefited from jaw-friendly rearing, all under the supervision of dentists familiar with forwardontics. From birth, encourage children to keep their mouths closed when they’re not eating or talking. This will support proper oral posture, which is lips closed, tongue on the palate, and teeth lightly touching. And wean to tough foods that require chewing, like they did in the days of hunter-gatherers. Perhaps the cheeriest news on the jaws front, particularly for orthodontists, comes from the clinical front. We can prevent this problem, argue Kahn and Ehrlich. Parents should encourage their children to wean to tough foods that require chewing, like humans did in the days of hunter-gatherers. Also to keep their mouths closed when they’re not eating or talking. Proper oral posture with the lips closed, the tongue on the palate and the teeth lightly touching
