Jaws The Story Of A Hidden Epidemic Epub Download

There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways?

Modern industrialized societies are plagued by small jaws and crowded, ill-aligned teeth, a condition that the dental profession refers to as malocclusion (literally bad bite). Malocclusion is often accompanied by mouth breathing. Together, not to mention their negative effects on appearance, the two tend to reduce our quality of life and make us more susceptible to disease. And they are increasingly common. William Proffit, author of the most widely used textbook in orthodontics, the part of dentistry focused on straightening crooked teeth, pointed out the scale of the epidemic in the United States in 1998: Survey data reveals that about a fifth of the population has significant malocclusion, and irregularity in the incisors (crowding of the front teeth) is severe enough in 15% that both social acceptability and function could be affected. Well over half have at least some degree of orthodontic treatment need. A study of people in Sweden in 2007 showed that about a third of the population was in real need of orthodontic treatment and almost two-thirds has real or borderline need. Orthodontist and clinical director of the London School of Facial Orthotropics, Dr. Michael Mew, asserts that 95 percent of modern humans have deviations in dental alignment; 30+ percent are recommended to have orthodontic treatment (half have extractions); and 50 percent have wisdom teeth removed. If industrialized societies are plagued by jaw problems, might it not be smart to consider what changes might be made in those societies to ameliorate the problems?

A few months ago, my friend Barry Isaacson actually did find a cache of old papers hidden in a secret compartment in his house. The real-life horror story they revealed is enough to give any child, or parent, nightmares. 006ab0faaa
