Easy to read and well written. The narrator was soft-spoken and dry but the info is fascinating. Coming off of Breath by James Nestor, I am ready to talk to the dentist and ortho! Highly recommend!

This is an extremely compelling and fascinating book, but it requires properly calibrated expectations beforehand. You should begin this book knowing that the central theory requires that the authors ‘cover their bases’ — meaning that they have to review somewhat dry and esoteric material.

Evolutionary biology meets orthodontics.  Jaws was a short but very informative book about the development of our jaws.  The saying goes, "You are what you eat." It turns out that how you eat is just as important, and equally important is how you prepare what you eat, specifically for babies and kids.

Bad mouth posture can lead to narrowing of the jaw, which can lead to a plethora of ailments such as diseases and the dreaded sleep apnea.

Consider this book if you're a parent, or find yourself with ortho issues

This book is aimed towards those that can influence jaw development in children. As an adult already dealing with jaw issues, it was rarely helpful, unfortunately. Before picking up this book, I'd first recommend "Breath" by James Nestor, as it discusses similar topics in a better, more enjoyable, manner.

A few notes...
page 65 - "long face syndrome" - associated with pattern of keeping upper and lower teeth just 2 mm apart - a.k.a. mouth breathing, even if lips are closed

page 91 - The ideal oral-facial resting position entails three things: lips closed, tongue on the palate, and teeth touching lightly together. << This is probably the key detail of book.

page 110 - Example of 30-year-old woman suffering from headaches and poor sleep. As a teen she had had braces and healthy permanent teeth extracted [similar to me]. This has a retrusive effect on the jaws, face, and throat. This orthodontic strategy is now known to lead sometimes to airway problems and/or pain in the temporomandibular joint (TMJ). After she had the spaces orthodontically opened as an adult, and had four dental implants to replace the removed teeth, all her sleep-disturbed-breathing and pain symptoms disappeared. Similar cases are not rare.

page 135 - adult forwardontics, using Homeoblock and the oral-nasal airway system (OASYS) to widen dental arch and advance lower jaw, making more room for tongue and tending to open nasal passages, improving the capacity of airway

page 136 - In curing malocclusion, the upper jaw almost always needs to be encouraged to move forward, and that is the foundation of forwardontics.

page 142 - To get a true gauge of the potential effects [of tooth removal on airway], one needs to examine x-rays taken 20 years after tooth removal. Extraction usually leads to a gradual shrinkage in the volume of the mouth. // Despite continuing defensive attempts to exonerate orthodontics from responsibility for the onset of obstructive sleep apnea (OSA), we now have multiple studies with solid evidence that link the loss of individual teeth or the smaller size being unequivocally linked to OSA.

An excellent read, I stumbled upon it in one of the podcast and boy it was a good recommendation. We all need to seriously think about our Jaws, not only it makes you think, it makes you ponder.

In the 1830s, before the American Civil War, a Philadelphia attorney and a talented artist, named George Catlin, made a series of trips to American West, visiting tribes and villages of Native Americans. Caitlin became fascinated by them and decided to document their culture and their ways of life. In his travels, he noticed, among other things, the difference in facial structure of the Native Americans compared to the people of European background. Specifically, he was struck with “their beautiful sets of teeth, of all ages, which are scrupulously kept together, by the lower jaws being attached to the other bones of the head.”

Caitlin noticed that Native Americans kept their lips closed nearly all the time, they breathed through the nose, and that they were more healthier that the newcomers in the continent. They called the whites not only “palefaces” but also “black mouths” because their mouths were open and their lower jaws were hanging down. Caitlin, as many Europeans, was a mouth breather but after noticing the Native Americans he changed his pattern of respiration and taught himself to nose breath.

Wanting to convince others to the benefits of nose breath, Caitlin wrote a short book, The Breath of Life (1861), which later retitled as Shut Your Mouth and Save Your Life. In this he “condemned the mouth breathing and assigned an array of ills to it, including ‘derangement’ of the teeth. George Caitlin and his book have been forgotten, but, as later research show he was onto something.

And then, Sandra met Paul. Sandra Khan is a pioneering orthodontist focused on a practise called orthotropics or forwardontics. Paul R. Ehrlich is a renowned evolutionist and a pioneer in alerting the public to the problems of overpopulation. Over dinner Sandra recounted to Paul her personal journey in her profession and the result was this excellent and valuable book, Jaws: The story of a hidden epidemic. The purpose of the book is to introduce the readers to the vast problem of oral-facial health. Kahn’s and Ehrlich’s basic premise is that that modern humans are developing smaller jaws, and as a result, our teeth are coming in more crowded or crooked. Moreover, it has impacts on our breathing pathway, which is becoming more crowded than ever. The tongue, too big for the restricted jaw, it falls back and restricts the passageway between the nose and the lungs, “causing a rhythmic rumbling sound,” also known as snoring.

The problem is the “poor oral posture”, argue Kahn and Ehrlich, which is exacerbated by the fact that we spend most of our lives indoors where concentrated allergens help stuff up our nasal passages and further constricting our vital breathing pathway. Smaller jaws, constricted air pathway, and sleep disrupted by snoring, a cause of sleep apnea, are “linked to serious lifelong health problems” including “ADHD, depression, cancer, and heart disease.”

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

Reading Jaws, I couldn’t stop thinking the brief lessons I once had on Hatha yoga. In Hatha yoga breath-control exercises, known as pranayamas, can help quiet the mind and reduce anxiety and stress. Nasal breathing is an extremely important part of the Hatha yoga. During this process, you slow down and control your breath. You inhale and exhale through your nose.

So, with each breath remember, noses are made for breathing!
