Pediatric Obstructive Sleep Apnea (OSA) is one of the most overlooked causes of poor sleep, behavior issues, and developmental challenges in children. In this episode of TMJ Unlocked, we break down exactly what pediatric OSA is, why it happens, and how airway growth, tongue posture, and jaw development all play a role. Dr. Gunnerson explains the airway, making complex anatomy easy to understand.

We also cover the AHI Index (Apnea‑Hypopnea Index) — the scoring system used to diagnose sleep apnea — and what the numbers actually mean for kids. Parents, dentists, orthodontists, ENTs, and sleep professionals will all find value in this full explanation of how airway structure affects breathing and sleep.

In this episode you’ll learn:

Pediatric OSA basics and early warning signs

AHI Index ranges for children and adults and what “mild,” “moderate,” and “severe” mean

Airway anatomy explained

Airway‑focused orthodontics and how jaw growth impacts breathing

Tongue posture, nasal breathing, and facial development

TMJ and airway connections often missed in traditional dentistry

How mouth‑breathing affects sleep, behavior, and long‑term health

AHI Index Quick Guide:

Normal: AHI < 1

Mild Pediatric OSA: AHI 1–5

Moderate Pediatric OSA: AHI 5–10

Severe Pediatric OSA: AHI > 10

Understanding these numbers helps parents and clinicians identify when a child’s sleep is being disrupted and when intervention is needed.

If your child snores, mouth‑breathes, grinds teeth, struggles with sleep, or shows signs of ADHD‑like behavior, this episode gives you the full breakdown of what might be happening and why.
