Improving Sleep, One Custom Solution at a Time
We aim to improve quality of sleep by helping patients suffering from mild to moderate obstructive sleep apnea and snoring. We create a 3D dental scan of your mouth to make a custom sleep appliance – about the size of a retainer – that brings your lower jaw forward slightly. The appliance keeps your airway open while sleeping, preventing the airway collapse that causes sleep apnea. This helps you breathe better when sleeping.
Benefits of a Dental Sleep Appliance
- Comfortable to Wear
- Portable
- Non-invasive
- Custom Fit
- Nothing to Plug in
- Doesn’t Make Noise
A Simple Path to Better Sleep
Once diagnosed for mild to moderate obstructive sleep apnea by your physician, give our office a call to schedule your appointment. We will assess and create a 3D dental scan of your teeth to make a custom dental appliance. When the appliance is completed, we fit the appliance to your mouth and give you all the information you’ll need to start sleeping better.

What is Obstructive Sleep Apnea?
Obstructive Sleep Apnea is when you stop breathing during your sleep because of a blockage of the windpipe. This blockage of airflow can cause your blood oxygen levels to drop. As a survival reflex, your brain wakes you up just enough to breathe, disrupting your sleep. This leads to daytime exhaustion and many other medical complications.
