How does the SomnoDent work?

The SomnoDent oral sleep appliance treats obstructive sleep apnea (OSA) by advancing the lower jaw which keeps the airways open. The appliance is custom-made to fit your mouth and consists of upper and lower splint that cover your teeth and will be titrated to advance your lower jaw throughout the treatment process. As your jaw moves forward it, in turn, helps open your airway allowing you to breathe easier and sleep more comfortably for longer periods of time, helping you to reach deep, REM sleep.

Are there side effects or complications from wearing a SomnoDent oral device?

As with any medical treatment, there are possible complications or side effects of dental sleep therapy. Considering the well-documented health risks of leaving obstructive sleep apnea (OSA) untreated, most of the side effects or using COAT™ (Continuous Open Airway Therapy) are considered minor. However, most patient’s side effects will subside after the first week or two. The three primary side effects are tooth discomfort, TMJ (jaw joint) or muscular discomfort, and tooth movement or bite changes. Although other minor complications are possible, like salivation changes and dry lips.
• Tooth discomfort is the most likely complication of COAT™ (Continuous Open Airway Therapy) but is also generally the least concerning. SomnoDent oral devices can put pressure on the teeth and may cause temporary soreness. If this does occur it can often be easily alleviated by adjustment of the oral device. Research suggests that there is no evidence of long-term tooth discomfort with properly fitted dental sleep devices. • SomnoDent oral devices work by moving the lower jaw forward to open the throat and collapsible airway. Due to this forward positioning of the jaw, there is a risk of TMJ (jaw joint) muscle discomfort. SomnoDent oral devices are adjustable, so each device can be adjusted gradually to help achieve advancement with minimal discomfort. Long-term muscle discomfort is rare. Short term discomfort is usually treated by adjusting the dental device to a more comfortable setting. Certain patients with existing TMJ (jaw joint) problems may not be able to wear dental devices, while other patients with TMJ (jaw joint) problems may actually improve their jaw problems by wearing a dental device. A trained SomonDent sleep dentist will be able to help determine solutions to a patient's discomforts or concerns. • SomnoDent oral devices are custom fit to the patient's mouth and consists of an upper and lower splint that cover the teeth. Due to the devices fit, there are forces exerted on the teeth and on the jaw while wearing a SomnoDent device. These forces can cause teeth to move slightly, or the forces can cause the jaw to be repositioned which can change their bite. There are recommended jaw exercises that can be done for a few minutes each morning after wearing the dental sleep device that will help reset the patient's bite. Despite the above described side effects, however, obstructive sleep apnea may pose serious health risks and should be treated. It disrupts normal sleep patterns, can reduce normal blood oxygen levels, and may result in excessive daytime sleepiness, irregular heartbeat, high blood pressure, heart attack or stroke. Although some changes might be undesirable in certain patients, the effective treatment of a life-threatening disease such as sleep apnea supersedes the maintenance of regular bite. Even if major tooth movements are seen, the discontinuation of oral appliance treatment should occur only if the patient accepts another treatment form, such as a CPAP (Continuous Positive Airway Pressure) device, as directed by a physician.

Is a SomnoDent oral device comfortable?

Most patients easily adapt to wearing a SomnoDent oral device at night. After wearing the device for a short period of time it will become part of their routine, and most people will hate to go to sleep without it after they realize how much better they feel in the morning (and how much better their bed partner sleeps as well). Compliance rates for dental sleep therapy are much higher than for other forms of non-surgical treatment of obstructive sleep apnea. In other words, patients are much more likely to use a dental device successfully than any other form of treatment. A recent survery indicated that 90% of SomnoDent patients regularly use their device. Once patients experience better sleep and improved health associated with the use of a dental device, it is rare for someone to stop using it.

What is involved in getting a sleep apnea oral device?

Once the dentist has completed the initial assessment, impressions or moulds of your teeth are taken. The custom made device is made in a specialist dental laboratory. The completed device is then fitted in the next visit, about one month later.

How effective are sleep apnea oral devices in eliminating snoring?

There is a substantial amount of research which confirms that these devices can be used successfully to eliminate or reduce snoring. The custom-made devices can be adjusted over time to achieve optimum results. The overall level of success is about 90%.

How often will the device need to be replaced?

The lifespan of the device depends to some extent on the type of appliance made. However, they are made of hard acrylic, so they are 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.

Can use of these sleep apnea oral devices damage my teeth?

Your treating dentist will carefully assess your teeth before getting the device made to avoid difficulties. Custom-made sleep apnea oral devices can theoretically cause teeth to move. Fillings or crowns that are loose or ill fitting can also be dislodged when taking the device in and out of the mouth. Patients who have uncontrolled dental decay or gum disease will be advised to treat these problems before an appliance is made.

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 devices 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. That's why it is important to have a sleep study conducted to determine if apnea is occurring. We provide take-home sleep study appliance to detect episodes of apnea during sleep. After usage, the appliance will be returned to your dentist and the data collected will be analysed. If sleep apnea is present or if snoring is obstructing one’s quality of life, your dentist 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 the age of 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 a sleep apnea oral device?

While CPAP is 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 worse, will end up not wearing them. A sleep apnea oral device is a more popular alternative to the CPAP. This device is small, portable, easy to clean, fits more comfortably and can provide similar treatment benefits.

How long will I have to use the oral appliance?

Obstructive sleep apnea in unlikely to decrease with age; therefore your sleep apnea oral device 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 sleep appliance 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 in the long run.
