Do You Recognize These Signs?

Sleep Apnea Affects More Than Just Sleep

Untreated sleep apnea raises your risk for heart disease, high blood pressure, diabetes, and stroke. If you or your partner notice these symptoms, it's time to talk to a specialist.

Loud, Chronic Snoring

Snoring that disturbs your partner or wakes you up is one of the most common warning signs.

Waking Up Exhausted

You sleep 7–8 hours but still feel drained. Your brain is being starved of oxygen all night.

Gasping or Choking at Night

Your airway collapses repeatedly — causing you to gasp, choke, or stop breathing momentarily.

Morning Headaches

Recurring headaches upon waking are a direct result of low oxygen levels while you sleep.

High Blood Pressure

The repeated oxygen drops during sleep put enormous strain on your cardiovascular system.

Difficulty Concentrating

Brain fog, poor memory, and irritability are all signs your brain isn't getting enough rest.

Meet Your Sleep Specialist

Dr. Pegah Mashayekhi, DO

🎓 Board-Certified, Sleep Medicine 🎓 Board-Certified, Obesity Medicine ● Internal Medicine

Dr. Mashayekhi brings a rare combination of sleep medicine and internal medicine expertise to Tri-City Dental. As a board-certified sleep specialist, she understands that sleep apnea is far more than just a snoring problem — it's a systemic condition that impacts your heart, metabolism, and brain.

Her approach is patient-first: understand the root cause, find the least invasive solution that works, and make sure you actually stick with it. For many of her patients, a custom oral appliance is a life-changing alternative to the CPAP they've been avoiding.

Oral Appliance Therapy

A Comfortable, Quiet Alternative to CPAP

Oral Appliance Therapy (OAT) uses a small, custom-fitted mouthguard worn during sleep. It gently repositions your jaw to keep your airway open — no mask, no hose, no noise.

🚹 Traditional CPAP

Bulky mask covering nose and mouth
Machine noise disturbs partners
Requires electricity and distilled water
Difficult to travel with
Low compliance rate — many give up
Can cause skin irritation and dry mouth

🌟 Oral Appliance Therapy

Small, custom-fitted device — fits in your pocket
Completely silent — no machine noise
No electricity, no distilled water needed
Travel-friendly — goes anywhere you do
High compliance rate — patients actually wear it
Comfortable and easy to care for

Is OAT right for me? Oral appliance therapy is most effective for mild to moderate sleep apnea and for patients who can't tolerate CPAP. Dr. Mashayekhi will review your sleep study results and recommend the best treatment for your specific case.

Getting Started Is Simple

3 Steps to Restful Sleep

From your first visit to your first full night of sleep — here's exactly what your journey looks like at Tri-City Dental.

In-Office Evaluation

Dr. Mashayekhi reviews your symptoms, sleep history, and any existing sleep study results. We examine your jaw, airway, and bite to determine if oral appliance therapy is right for you. No referral needed.

Custom Device Fitting

We take precise digital impressions of your teeth and bite. Your custom oral appliance is fabricated to fit your unique anatomy — no generic, off-the-shelf device. We fine-tune the fit until it's exactly right.

Restful Sleep Begins

Wear your appliance each night. Within days, most patients notice dramatically improved sleep, less snoring, and more energy. We schedule follow-ups to track your progress and adjust if needed.
