Sleep Apnea Treatment in Rockwall, TX
Also Serving Royse City, Heath, and Surrounding Communities

Sleep apnea is one of the most common and most underdiagnosed sleep disorders in the country. It happens when the airway repeatedly collapses or becomes blocked during sleep, causing brief pauses in breathing throughout the night. Most people with sleep apnea have no idea it is happening. They just know they wake up exhausted, struggle through the day, and never feel truly rested no matter how many hours they spend in bed.
At Karen E. Williamson, DDS in Rockwall, Dr. Williamson screens for sleep apnea and offers an effective oral appliance treatment that works for patients who cannot tolerate CPAP, or who are looking for a simpler and more comfortable solution. If you or someone in your household snores, gasps, or seems to stop breathing during sleep, a screening is a good place to start. Call our office at 469-402-0024 to schedule a sleep apnea consultation and get on the path to better sleep today.
Tired of Your CPAP? There is Another Option
CPAP machines are the most widely prescribed treatment for sleep apnea, but they are not the right fit for everyone. If you have found yourself avoiding your CPAP because it is uncomfortable, noisy, claustrophobic, or just impossible to sleep with, you are not alone. CPAP intolerance is one of the most common reasons sleep apnea goes untreated.
The good news is that an oral appliance can be just as effective for many patients, and it fits in the palm of your hand.
Here’s a breakdown:
Comparing Oral Appliance vs. CPAP
| CPAP Machine | Oral Appliance (ProSomnus) | |
|---|---|---|
| How it works | Pressurized air keeps airway open | Gently repositions the jaw to open the airway |
| Comfort | Mask, hose, and air pressure can be difficult to tolerate | Fits like a mouthguard, no mask or straps required |
| Noise | Machine produces noise throughout the night | Silent |
| Travel | Bulky, requires power source | Fits in a small case, no power needed |
| Maintenance | Regular cleaning of mask, tubing, and reservoir | Simple daily rinse and brush |
| Insurance coverage | Typically covered | Most medical insurance plans cover oral appliance therapy |
Studies show that oral appliance therapy achieves comparable effectiveness to CPAP for many patients, with significantly better long-term compliance. A treatment you will actually use every night is more effective than one that sits on the nightstand.
The ProSomnus Oral Appliance

At our Rockwall office, Dr. Williamson uses the ProSomnus oral appliance to treat obstructive sleep apnea and snoring. ProSomnus is an FDA-cleared, precision-engineered device that fits over the upper and lower teeth, similar to a mouthguard. It works by gently holding the lower jaw slightly forward during sleep, which keeps the airway open and prevents the tissue collapse that causes apnea and snoring.
Unlike older oral appliance designs, the ProSomnus EVO is custom-made using advanced CAD/CAM technology and high-performance medical-grade materials. It is small, comfortable, BPA-free, and metal-free. Patients who have tried other appliances or struggled with CPAP consistently report that the ProSomnus fits better and is easier to wear through the night.
- FDA-cleared for the treatment of obstructive sleep apnea and snoring
- Custom-fabricated from impressions of your teeth for a precise fit
- No masks, hoses, machines, or power required
- Compact enough to travel anywhere
- BPA-free and metal-free construction
- Covered by most medical insurance plans
What Is Sleep Apnea?
Sleep apnea is a common disorder characterized by repeated pauses in breathing during sleep. It prevents the sufferer from receiving adequate oxygen or the restorative sleep they need, and can be caused by a number of factors including sleeping posture, airway anatomy, and mouth positioning.
Sleep apnea is a serious health concern linked to daily exhaustion, difficulty concentrating, and accident proneness, as well as obesity, diabetes, heart disease, and depression. Dr. Williamson is passionate about helping patients overcome it. She understands that treating sleep apnea can mean better sleep, better health, and a meaningfully better quality of life.
If you or a family member has noticed snoring, choking, or gasping during sleep, come see Dr. Williamson for a sleep apnea screening in Rockwall.

Sleep Disorder Screening
For your sleep apnea screening, you will complete questionnaires involving your sleep and family history to help Dr. Williamson learn about your risk factors. During your screening, she will review your questionnaires and perform an airway evaluation. She can help you identify any symptoms of sleep apnea and the cause of your disorder so that you can start working towards more restful sleep.
