Most people assume sleep apnea is a medical problem, handled by a doctor with a sleep study and a CPAP machine. What many don’t realize is that the mouth, jaw, and airway sit at the center of the problem, and a trained dentist is often the first clinician to spot the signs.
At Santa Teresa Smiles, Dr. Noha Oushy is airway certified through The Breathe Institute, a leading center for sleep and breathing research founded by Dr. Soroush Zaghi. That training shapes how she approaches every exam, looking beyond teeth and gums to evaluate how her patients breathe.
What Sleep Apnea Actually Is
Obstructive sleep apnea happens when the soft tissues of the throat collapse during sleep and partially or fully block the airway. Breathing stops, the brain sends an alert, the body jolts awake just enough to restart breathing, and the cycle repeats throughout the night, sometimes hundreds of times.
Most people never know it’s happening. They just wake up tired, reach for coffee, and push through. Common signs include:
- Loud snoring or gasping during sleep
- Waking with a dry mouth or sore throat
- Morning headaches
- Daytime fatigue regardless of how long you slept
- Difficulty concentrating or mood changes
- Teeth grinding or clenching at night
Why the Dentist Sees It First
Dentists examine the mouth, tongue, jaw, and throat at every visit. Worn teeth from grinding, scalloped edges on the tongue, a narrow palate, or a low-positioned soft palate are all signs that show up in the dental chair long before a formal sleep diagnosis is made.
Dr. Noha Oushy screens for airway risk as part of a comprehensive exam at Santa Teresa Smiles, asking about sleep quality, energy levels, and breathing habits. This is not standard in most dental offices. It is a direct result of her advanced airway training.
The Mouth-Airway Connection
The structure of the jaw and oral cavity directly determines how much space the airway has. A narrow palate leaves less room for the tongue, which can fall back during sleep and restrict airflow. A recessed jaw positions the throat tissues in a way that increases collapse risk. Tongue tie, a restricted lingual frenum, can also limit tongue mobility and force the tongue into a lower, more obstructive position during sleep.
Dr. Zaghi’s research at The Breathe Institute has documented the connection between tethered oral tissues, jaw structure, and obstructive sleep apnea in depth, and it underpins much of how airway-certified dental providers like Dr. Oushy approach evaluation and treatment.
What Dental Treatment Can Do
A CPAP machine delivers pressurized air to keep the airway open during sleep. It works well, but many patients find it difficult to tolerate long term. For mild to moderate sleep apnea, dental appliances offer a well-researched alternative.
Mandibular advancement devices gently reposition the lower jaw forward during sleep, which increases upper airway space and reduces the tendency for soft tissues to collapse. These appliances are custom fitted, worn at night, and often far more comfortable for patients who cannot tolerate CPAP. For some patients, they are used alongside CPAP to reduce the pressure settings needed.
Dental treatment for sleep apnea may also include palate expansion to create more tongue space, myofunctional therapy referrals to strengthen the tongue and throat muscles, and airway-focused orthodontic care, especially in children where early intervention can change the developmental trajectory entirely.
For Those Who Want to Dig Deeper
If you are curious about the science of breathing and how profoundly it shapes health, a few books are worth your time. Breath by James Nestor is an accessible, eye-opening read on how modern humans have lost the ability to breathe well and what it costs us. This book is an excellent starting point for patients who want to understand the bigger picture before their next appointment.
What to Do If You Recognize Yourself Here
If you snore, wake up tired, or have been told you stop breathing during sleep, bring it up at your next visit to Santa Teresa Smiles. Dr. Noha Oushy can screen for airway risk, evaluate your jaw and oral structure, and connect you with the right providers if a formal sleep study is the right next step.
Breathing well at night is not a luxury. It affects every system in the body, from cardiovascular health to immune function to how your brain consolidates memory. Getting it evaluated is one of the most valuable things you can do for your long-term health.
