What Is Airway Orthodontics

Your teeth aren’t the
whole story.

Traditional orthodontics straightens teeth. Airway orthodontics goes deeper — addressing how your jaw, airway, and breathing patterns develop. Poor airway development doesn't just cause crooked teeth. It affects sleep, behavior, focus, health, and quality of life at every age.

As the first certified airway orthodontist in Southern California, Dr. K brings a level of specialized expertise that simply isn't available anywhere else in the region.

🧒 Children Ages 3–12
Mouth breathing, crowded teeth, ADHD-like behavior, bedwetting, and night terrors are often signs of airway dysfunction — not behavioral problems. Early intervention changes everything.
🧑 Teens & Adults
Snoring, brain fog, morning headaches, anxiety, acid reflux, and unexplained weight gain can all trace back to how your airway developed. This is treatable at any age.
😴 Sleep & Breathing
We work alongside sleep medicine to address the structural causes of sleep-disordered breathing — without surgery, often without CPAP.
🦷 Beyond Straight Teeth
Vivos, Myobrace, BioX, and advanced appliance systems develop the jaw and airway — so teeth align naturally, and breathing improves permanently.
