What is Oral Appliance Therapy?
Oral Appliance Therapy (OAT) is a simple, non-invasive treatment for sleep apnea and snoring, OAT is a CPAP Alternative. You simply wear a precision-made mouthpiece, known as an Oral Appliance, while you sleep. It works by slightly repositioning your lower jaw to keep your airway open, allowing for correct breathing while you sleep.

However, this is a precision-made medical device custom fit to your anatomy to slightly reposition your lower jaw forward. This can help keep your airway open...allowing you to get the healthy restful sleep you have been looking for.

CPAP vs. Oral Appliance:
7 Benefits of Oral Appliance Therapy Over CPAP

1. Comfort
No hoses, no mask, and no machine means you sleep more comfortably in any position. A great option for side-sleepers, stomach sleepers, and tossers & turners.

2. Convenient
There are no wires, nothing to plug in or strap on your face. Simply put your Oral Appliance in your mouth right before bed and you’re good to go.

3. Quieter & Less Disruptive
Unlike a noisy CPAP machine, it doesn’t use electricity and makes no noise. Your bed partner is sure to thank you.

4. Easy to Clean
It requires much less cleaning and maintenance than CPAP. It’s about as easy as brushing your teeth.

6. Less Expensive
CPAP requires disposable filters and replacement parts which significantly adds to the cost. Over a five-year period, CPAP costs about 2-to-3 times more than an Oral Appliance.

7. Improves Sleep Quality
It’s designed to help keep your airway open and mouth closed during sleep. This means you’ll get more healthy restful sleep.
