The Great Contraction: A New Frontier in Pediatric Airway Health

The Silent Pandemic Hiding in Plain Sight For 99% of human history, the normal human face was a masterpiece of expansive architecture—broad dental arches, wide airways, and structural integrity. Today, we are witnessing a craniofacial collapse. Modern industrial life has triggered an evolutionary mismatch, resulting in a generation of children with narrow palates, recessed mandibles, and compromised airways.

In The Great Contraction, Dr. Leslie Pasco synthesizes anthropological history with cutting-edge clinical data to reveal that mouth breathing, restless sleep, and dental crowding are not merely orthodontic inconveniences—they are developmental emergencies.

A Call to Collaboration

The mouth cannot be treated in isolation. This book is a heartfelt mandate for physicians, dentists, and myofunctional therapists to bridge the gap between their practices.

Our goal is no longer just to straighten teeth—it is to restore our biological heritage and ensure every child has the oxygen and sleep they need to reach their full genetic potential.

Dr. Pasco challenges clinicians, parents, and educators to rethink early intervention, functional development, and prevention. The science is compelling. The clinical correlations are clear. And the urgency is real... Myofunctional science is no longer niche—it is foundational to modern health optimization.
