Sandra Kahn, DDS, MSD, is a recognized leader in craniofacial growth and development, airway efficiency, athletic performance, and early-life feeding physiology. She is a Diplomate of the American Board of Orthodontics. Her career includes extensive academic and clinical collaboration with institutions such as UNAM, CES, UC Berkeley, UCSF, and Stanford, where she has conducted clinical work and research in anthropology, evolutionary biology, orthodontics, sleep medicine, and infant feeding development.

She has pioneered science-based approaches to airway training, nasal breathing, optimal oral posture, and physiologic feeding mechanics. She is the inventor of Nutriflo and Paciflo, innovative infant feeding and soothing systems designed to support natural swallowing, jaw development, and nasal breathing from birth. She holds nine patents for devices that improve facial growth, promote relaxed resting posture, support physiologic swallowing, optimize sleep quality, and enhance athletic recovery. Dr. Kahn has published seminal scientific work in BioScience, providing a definitive perspective on the causes and prevention of malocclusion. More recently, she published the first clinical study demonstrating improved sleep efficiency and reduced sleep latency using her Up-Locker device in the prestigious journal Pediatric Pulmonology.

She is the author of seven books, including Let’s Face It: A Guide to Your Child’s Optimal Health, Facial and Dental Development; GOPex: Good Oral Posture Exercises; Jaws: The Story of a Hidden Epidemic; Breathe 4.0; and Forwardontics Protocols, and has translated The Cause and Cure of Malocclusion. She also recently completed NOse, co-authored with Paul Ehrlich, exploring nasal function, nitric oxide physiology, and the optimization of human health and performance. She coined the term Forwardontics to describe her growth-based, airway-focused approach to orthodontic treatment.

Her work has been applied by professional athletes in Germany and internationally and integrated into early-life health programs worldwide. These unique, science-based protocols translate airway physiology into practical, actionable methods for parents supporting healthy infant development, biohackers seeking to improve healthspan, children developing strong jaws and efficient airways, individuals optimizing sleep and recovery, and athletes striving for peak performance.
