Oral health, sleep & your airway
How you breathe and sleep is closely tied to your airway, jaw, and oral health.
What the research describes
Sleep-disordered breathing and dental findings travel together. Large sleep studies report that teeth grinding is highly prevalent among adults with obstructive sleep apnea, and the mouth carries other early signals too: worn enamel, scalloped tongue edges, dry mouth, a narrow airway visible on examination.
Why it matters for prevention
Untreated sleep apnea is associated with high blood pressure, heart disease, stroke, and diabetes. Because dental visits happen more often than sleep studies, the mouth is a realistic place to catch the first hints, and a dental appliance is sometimes the treatment a patient will actually wear.
How we look at it here
We assess your airway, bite, and signs of grinding as part of your comprehensive exam. When an oral appliance is the right fit, we make it custom; when it is not, we say so and coordinate with your physician. Diagnosing sleep apnea is a medical diagnosis. Our role is to notice, evaluate, and refer.
By the numbers
Findings as reported in the studies linked below. Every figure was read from the source itself. Where a result is borderline or contested, we say so.
- 49.7%
- Of 914 adults with obstructive sleep apnea studied in a sleep laboratory, nearly half also had sleep bruxism — teeth grinding your dentist can see evidence of long before a sleep study happens. Li 2023, polysomnographic study
- OR 1.65 95% CI 1.21–2.25
- Higher odds of obstructive sleep apnea among people with periodontitis, pooled across 6 studies. Molina 2023, meta-analysis

Does your sleep sound like this?
These are the signals we look for when we assess an airway. Check anything that sounds like you. It stays on your device, and nothing is sent anywhere.
The real screening is already in your paperwork.
When you schedule as a new patient, your intake forms include the two validated sleep screeners clinicians use: the Epworth Sleepiness Scale and STOP-BANG. You fill them out online before you arrive, we score them, and we go through the results with you at your visit. Nothing to print, nothing to remember to bring.

This self-check is educational and is not a diagnosis or a validated screening test. Only a sleep study, ordered and read by a physician, can diagnose sleep apnea. If any of this sounds familiar, talk with us and with your doctor.
Curious what your own mouth is telling us?
Your comprehensive first visit includes live microscope bacterial analysis, an airway look, and a full health-history conversation. About 90 minutes, no rush.
