Sleep Is the Healing Strategy
Michael Bennett, DDS, PhD
Good morning. This is More Than Teeth. The newsletter that helps dental sleep professionals get 1% better every week.

Good morning.
"Your body is designed to heal—but only if you let it rest. And real rest starts with the airway."
In medicine, we often say, "The body heals itself." But here's the hidden truth: healing is a privilege for those who can breathe and sleep well.
Night after night, thousands of patients lie down, hoping to recharge... but wake up more tired. Why? Because their airway is collapsing. Oxygen dips. The brain panics. The body never gets into deep, restorative sleep.
As dentists, we can change that.
In Today’s Edition:
Sleep as Medicine — Learn why deep sleep is your body's most powerful healing tool and how airway issues can disrupt it.
Signs in the Smile — Discover how cracked molars, scalloped tongues, and narrow palates may indicate your patient has nighttime breathing issues.
From Symptoms to Systems—Discover how airway treatment transforms care from quick fixes to lasting wellness and recovery.

Key Takeaways🔑
Sleep is where healing happens. If your patient isn’t getting deep sleep, their immune system, hormones, and nervous system can’t recover.
Dentistry is a frontline sleep specialty. We see the airway daily, and often earlier than any physician does.
Treat the airway, transform the outcome. From orthodontics to pain cases to wellness-focused care—it all starts with sleep.
Why Sleep Matters More Than We Think
Healing depends on parasympathetic activation—that rest-and-digest mode that lets inflammation settle, tissue repair begins, and hormones regulate. But airway issues like obstructive sleep apnea (OSA) keep patients locked in a chronic stress (sympathetic) cycle.
That cycle looks like this:
Persistent jaw pain
Slow surgical healing
Worsening bruxism
Hormonal dysregulation
Emotional lability (mood swings, anxiety, even depression)
We are not just fighting fatigue. We're fighting a healing bottleneck.
Recent research confirms this: During deep (slow-wave sleep), the body releases growth hormone, boosts immune cell activity, and reduces inflammatory cytokines. These processes are essential for physical repair and immune regulation.
Emerging research continues to confirm what many have long suspected: lack of sleep weakens the immune system and delays healing. Studies now show chronic sleep loss elevates inflammation, reduces antibody production, and blunts the body’s ability to recover from injury or infection.
“Sleep is like software updates for your body,” says Dr. Michael Bennett, DDS, PhD. “Without it, your immune system glitches. Healing slows. Inflammation climbs. You’re running the system on yesterday’s settings.”
What to Look For In the Mouth

Fissured tongue

High-arched palate (narrow palate)
The airway leaves clues:
Broken and cracked molars
Scalloped or fissured tongue
High narrow palate and retrognathia
Open-mouth posture during cleaning
Excessive wear despite good hygiene
These aren’t just dental problems. They’re physiologic compensations for a blocked airway.
From Symptom Management to Systemic Healing
Patients don’t just want pretty teeth. They want to feel better. Live longer. Sleep through the night without grinding, snoring, or struggling to breathe.
When we treat the airway—whether in children with underdeveloped jaws or adults with undiagnosed OSA—we shift from symptom relief to systemic healing.
Oral appliance therapy, early airway ortho, myofunctional support, or even simply screening and referring — it all matters.
Thanks for being part of this movement. You are not "just" a dentist. You're a sleep-aware healer in a healthcare system that desperately needs more of them.
Stay curious. Stay compassionate. And remember: it's always been about more than teeth.
