Sleep Apnea

Do you have trouble sleeping? If so, you’re not alone. An estimated 22 million Americans suffer from a lack of sleep—and even exhaustion—caused by sleep apnea. Chronic snoring problems and interrupted sleep aren’t just an inconvenience. Untreated sleep apnea can lead to more serious health risks. Sleep apnea is a common but serious sleep disorder that causes interruptions in breathing during sleep. These pauses in breathing are called apneas and they can happen hundreds of times each night. Sleep apnea can have a negative impact on your health and prevent you from getting the restful night’s sleep your body needs.

CPAP Device

With Continuous Positive Airway Pressure (CPAP), patients wear a specialized mask over the nose and face during sleep. The CPAP device delivers a steady supply of air, keeping the airway open. CPAP treatment can be very effective, however the patient must be willing to use it correctly and consistently.

Upper Airway Surgery

There are several surgical options. Nasal surgery can correct a deviated septum or remove bones in your nose to improve air flow. Surgery may also be performed to remove and/or reduce the size of the soft palate, uvula and back of the tongue. These surgeries are not typically recommended as first line treatments for obstructive sleep apnea.

He is a member of The American Dental Association (ADA), Michigan Dental Association (MDA) and the American Academy of Dental Sleep Medicine (AADSM). For the last few years, Dr. Williamson has changed his focus from practicing traditional dentistry to treating patients who suffer from Obstructive Sleep Apnea (OSA).

More about Dr. Williamson

Dr. Williamson learned about the role that a dentist can play in the treatment of OSA through his daughter, a Physician’s Assistant who treats OSA herself. She explained to her father that there was a void in the treatment of OSA because there were not enough qualified dentists with the understanding of how to treat these patients.

Dr. Williamson, who suffers from OSA himself, understands the devastating effects that this disease can have on a person’s quality of life. After following the route of traditional diagnosis and treatments including Home Sleep Tests, Laboratory Sleep Tests, CPAP and Bi-pap therapy, Dr. Williamson became very motivated to help himself as well as others who are stricken with this disease.

Dr. Williamson currently has over 140 hours of continuing education in Dental Sleep Medicine and has been recognized by the AADSM as having the “Qualified Dentist Designation”.

Common Questions

Regarding Sleep Apnea

If I snore, do I have sleep apnea?

Snoring frequently accompanies sleep apnea but it is not always an indicator of whether this sleep condition is present. However, snoring can indicate that bulky throat tissue could potentially obstruct airways – especially if patients have certain lifestyle factors that contribute to sleep apnea. Fortunately, the treatment we offer for sleep apnea and snoring is the same. By prescribing a custom oral appliance, the diameter of the airway can be widened to prevent the sounds of snoring as well as episodes of apnea. These oral appliances are soft and comfortable to wear. They work by positioning the lower jaw slightly forward so that the airway is no longer obstructed.

Is it possible that I have sleep apnea even if I don't snore?

Anyone of any age can have sleep apnea. Even though snoring can accompany sleep apnea, it is not always a symptom of this sleep disorder.  For your convenience, our practice provides a service in which a sleep test device can be mailed to your home. After usage, the device is mailed back to the medical service provider where a board certified sleep doctor will analyze the data. If we find that sleep apnea is present or determine if snoring is obstructing one’s quality of life, we will provide treatment recommendations.

What causes sleep apnea?

The exact cause of obstructive sleep apnea (OSA) is different for each person. Anyone can develop it, regardless of age or gender. The most common risk factors include:

  • Being over age 40
  • Having a large neck (over 17 inches in men, 16 inches for women)
  • Being overweight – approximately half of OSA sufferers are overweight
  • Being male – more men than women suffer from OSA
  • Having a large tongue or small jaw
  • Enlarged tonsils and adenoids (particularly in children)
  • Using alcohol or sedatives which relax the muscles in the airway
  • Nasal obstruction due to a deviated septum or sinus and allergy problems

What is the difference between a CPAP and an oral appliance?

While CPAP is very effective in treating sleep apnea, many people cannot tolerate the discomfort of  the mask and the inconvenience and noise of the machine. Therefore a high percentage of users have difficulty or will not wear them.  

An oral appliance is a popular alternative to the CPAP. This device is small, portable, fits more comfortably and can provide similar treatment benefits.

How do you confirm the effectiveness of the oral appliance?

You will have a follow-up sleep study while using your oral appliance to confirm the effectiveness of the device. A consultation with the sleep medicine physician will be necessary to interpret the results.

Does insurance cover sleep apnea treatment?

Insurance plans vary widely, but our experienced team has found that most insurance companies cover a significant amount of the cost for treatment. If coverage is available for oral appliances, it will come from your medical insurance carrier. Most dental insurance companies do not cover treatment of obstructive sleep apnea.

Our patients tell us it is well worth the investment of their time and money to treat their sleep apnea because of the improved quality of life they experience.

What if I don't have insurance?

We offer financing options and will work with you to find a solution that fits your needs.

How long will it take to adapt to the oral appliance? Will it hurt my teeth?

The majority of patients will adapt to the appliance within 5-10 days. It will take a few days to get used to having a device in your mouth while you sleep. The appliance will not hurt your teeth. If your teeth are sore after initial use, we can easily adjust it for your comfort.

How often will the appliance need to be replaced?

They are made of hard acrylic, which is very durable. They are typically replaced every 3-5 years depending on wear and tear. If you grind your teeth, you may have a more frequent rate of repair or replacement.

Will the appliance change my bite?

A change in your bite is possible. Depending on the position of your teeth and the status of your bone, your teeth may shift. This can be minimized with the use of a morning re-positioning device.

Are there any side effects of the appliance?

The most common side effect is morning muscle soreness that usually goes away after a short time. Some patients may experience either dry mouth or excessive salivation. As mentioned above, minor tooth movement occurs in some patients.

How long will I have to use the oral appliance?

Obstructive sleep apnea in unlikely to decrease with age; therefore your oral appliance will probably be a lifelong therapy. However, certain wellness factors such as significant weight loss may improve your symptoms.

Can’t I just order a boil and bite device off the internet?

While there are over-the-counter appliances you can order, keep in mind these are not FDA approved for treating sleep apnea. Additionally, when not fitted properly they may cause unwanted side effects such as jaw problems or excessive tooth movement.
