Anatomy of an Airway
A Sleep & Wellness Newsletter by Michael Bennett, DDS, PhD & Cathy Bennett, MS, NBCHWC
Good morning. This is More Than Teeth. The newsletter that helps dental sleep professionals get 1% better every week.

Good Morning,
You look at tongues, palates, jaws, and faces all day long. But what if you’ve been seeing airway dysfunction—and just didn’t know it?
This week’s Airway & Wellness Masterclass issue is about connecting anatomy to action. Dr. Bennett walks through what structures matter most in sleep screening—and why so many dentists hesitate to act. Plus, Cathy shares how something as simple as mouth breathing can become a whole-body stress signal.
In Today’s Issue:
What structural and soft-tissue signs reveal about airway risk
How to start using CBCT, facial posture, and oral volume as clues
Dr. Bennett’s dissertation insight: What “counts” for referral—and why many dentists feel unsure
Cathy’s perspective: Mouth breathing isn’t just airflow—it’s nervous system overload
Action step: Add one airway-related structure to your patient documentation this week

Clinical Corner
🥼Use the clinical corner as your secret weapon to impress your colleagues and patients!
Key Takeaways🔑
The airway isn’t just invisible—it’s readable through structure, function, and facial cues
CBCT, tongue posture, tonsil size, and jaw growth all provide vital airway insight
Dr. Bennett’s PhD research revealed many dentists lack confidence in which anatomical signs are referral-worthy
Mouth breathing can be a chronic stress signal, not just a habit
You don’t need a full airway workflow—just start documenting what you see
Anatomy = Clues. You Already Have the Tools.
Most dentists notice the signs long before a patient gets diagnosed with a sleep disorder:
Scalloped tongue
Enlarged tonsils
Narrow, vaulted palate
Anterior tongue tie
Retruded jaw or Class II profile
Flattened facial profile in kids
Forward head posture
What we don’t always know is what to do with those signs.
That’s where Dr. Bennett’s PhD research sheds light.
From Dr. Bennett’s Dissertation
Many of the dentists Dr. Bennett interviewed said the same thing:
“I see airway issues in the mouth—but I’m not sure what counts. I don’t want to overstep.”
What they needed wasn’t just permission—it was clarity.
So here’s a clinical takeaway:
“The highest-yield structures for airway screening are: tongue posture, tonsils, nasal valve patency, palate width, and mandibular position. You don’t need to diagnose—just document, describe, and refer when appropriate.”
— Dr. Michael Bennett, DDS, PhD
Cathy’s Corner: Why Mouth Breathing = Stress Breathing
We often treat mouth breathing as an orthodontic or habit issue. But chronically breathing through the mouth keeps the body in sympathetic overdrive—activating the fight-or-flight nervous system and making deep sleep harder to reach.
That’s why mouth breathing is linked to:
Poor healing
Clenching and TMJ symptoms
Emotional reactivity and anxiety (especially in kids)
Delayed growth and immune suppression
“Helping patients breathe better starts with helping them feel safe in their bodies.” — Cathy Bennett, MS, NBCHWC
Business of Sleep
Simple Charting Shift This Week:
Add one of the following to your patient note template:
Tongue posture
Tonsil grading
Facial profile or nasal breathing note
Palate shape or vaulting
This tiny change does two things:
Helps your team build awareness and pattern recognition
Creates documentation that supports collaboration and referrals
Bonus tip: Take consistent airway-focused photos at hygiene or ortho starts.

Miscellaneous
😅P.S. … From Dr. Bennett & Cathy:
You don’t need to master all of airway anatomy overnight. You just need to start seeing what you already look at—with a different lens. That’s when dentistry becomes life-changing.
