If your dentist hasn’t asked you about your sleep, you’re receiving substandard care.
I’ve seen it again and again. People come in with cavities, grinding, gum disease, kids with narrow palates—and no one’s ever connected it to how they’re sleeping at night.
Mouth breathing dries out saliva. That raises cavity risk and disrupts your oral microbiome. Grinding is often your body’s way of gasping for air. Kids who snore or toss and turn might be dealing with airway issues that shape the trajectory of their lives.
When I started asking about sleep in my practice, everything changed. We stopped chasing symptoms and started solving root causes.
Your mouth sets the tone for how you breathe. If you’re breathing through your nose, you’re filtering air, keeping nitric oxide levels up, and staying in a parasympathetic (rest-and-digest) state. But if you’re breathing through your mouth—especially at night—you dry out saliva, your mouth’s natural defense system.
That leads to more bad bacteria. More cavities. More inflammation. But it goes deeper. Mouth breathing reduces oxygen, which disrupts deep sleep and throws off your nervous system. Quality sleep is the foundation of everything else.
Grinding isn’t just a stress habit. It’s often your brain trying to open a blocked airway. That grinding wears down enamel and inflames the jaw—but it’s also a clue your body isn’t getting what it needs while you sleep.
Sometimes what looks like a dental problem is really sleep-disordered breathing—like UARS or undiagnosed sleep apnea. That’s why I refer patients for sleep studies or co-manage care with sleep physicians and myofunctional therapists. It takes a team.
Has a dentist ever talked to you about how you sleep? Let’s compare notes. Drop a comment.
And if you’re looking for a provider who sees the full picture, I built the to help. These are dentists who’ve stopped treating teeth in isolation. Functional dentistry is growing—and it’s long overdue.
