Jaws

de Kahn, Sandra Dr, Paul R. Ehrlich

Our jaws are getting smaller, and our teeth are growing in crooked and crowded, This creates not only aesthetic challenges but also difficulties with breathing. Modern orthodontics can straighten our teeth, but don't address the underlying causes of this rapid shift in oral evolution, and the health risks posed by obstructed airways. Kahn and Ehrlich discuss the biological, dietary, and cultural changes that have created this health challenge, and propose simple adjustments that can alleviate the situation.
