"Jaws: The Story of a Hidden Epidemic"

Guests: Sandra Kahn, DDS, MSD, Orthodontist; Paul Ehrlich, PhD, Professor of Population Studies Emeritus, President of the Center of Conservation Biology, Stanford University. Scientists who study skulls from thousands of years ago can tell you something surprising about our ancestors: they didn’t need orthodontists. Our ancestors, as a general rule, had great teeth: straight, strong, no crowding or impacted wisdom teeth or overbite. These days having perfect teeth without braces or some sort of dental work done is really rare in America. What changed?  Paul Ehrlich and Sandra Kahn explore that question in their new book, “Jaws: The Story of a Hidden Epidemic.” They claim that we, as industrialized humans, have a host of health problems because, from the time we’re born, we don’t force our jaws to work hard enough.
