If a physician has diagnosed you with obstructive sleep apnea, the next step often involves your dentist as much as your doctor. Oral appliance therapy is one of the most effective non-surgical treatments for mild to moderate sleep apnea, and Edmonton dentists trained in dental sleep medicine now provide it as a standard part of treatment. This guide walks through the types of appliances available, how the fitting process works, and what ongoing care looks like once you’re using one.

How a Dentist Works Alongside a Sleep Physician to Treat Sleep Apnea

Dentists don’t diagnose sleep apnea – that diagnosis comes from a sleep physician, usually based on an in-lab or home sleep study that measures how often your breathing is interrupted overnight. Once you have a diagnosis and a sense of severity, your physician may refer you to a dentist with training in dental sleep medicine to discuss oral appliance therapy as an alternative or complement to CPAP.

 

From there, the dentist and physician typically stay in contact throughout treatment. The dentist designs, fits, and adjusts the appliance, while the physician usually orders a follow-up sleep study once you’re wearing it consistently to confirm it’s actually reducing your breathing interruptions – not just your snoring.

Types of Sleep Apnea Oral Appliances: Mandibular Advancement Devices vs. Tongue-Retaining Devices

The most common option is a mandibular advancement device (MAD), which looks similar to a sports mouthguard and gently holds the lower jaw slightly forward during sleep. MADs are custom-made from an impression or digital scan of your teeth and usually include an adjustable mechanism so the degree of advancement can be increased gradually.

 

A tongue-retaining device (TRD) works differently — instead of moving the jaw, it holds the tongue forward using gentle suction. TRDs are prescribed less often, but they can be a good alternative for patients who can’t tolerate jaw advancement, have limited natural teeth to anchor a MAD, or have certain jaw joint concerns.

 

A few factors usually decide which type your dentist recommends:

 

  • How many natural teeth you have available to anchor a MAD
  • Whether you have any existing jaw joint (TMJ) discomfort
  • How severe your apnea is, based on your sleep study results
  • Your personal comfort and gag reflex, since the two devices feel quite different in the mouth

How Oral Appliances Keep the Airway Open

Obstructive sleep apnea happens when soft tissue at the back of the throat collapses during sleep and blocks airflow. By repositioning the jaw or tongue, an oral appliance creates more space behind the tongue and helps keep that airway open, which reduces the number of breathing pauses and often eliminates snoring as well.

 

It’s worth being clear that an oral appliance manages sleep apnea rather than curing it – the effect only lasts while the appliance is being worn, which is why consistent nightly use matters as much as the device itself.

Oral Appliances vs. CPAP: Which Is Right for You?

CPAP therapy remains the gold standard for moderate to severe obstructive sleep apnea because it delivers continuous air pressure that keeps the airway open regardless of position. Oral appliances are generally recommended for mild to moderate cases, or for patients who have been prescribed CPAP but can’t tolerate the mask, noise, or feeling of the machine long-term.

 

Appliances are smaller, silent, and easier to travel with, which is part of why adherence tends to be higher than with CPAP even though its nightly effectiveness can be slightly lower. Some patients also use both – a combined approach for nights when CPAP isn’t practical.

What Happens During Your Fitting Appointment

Your first appointment usually starts with a review of your sleep study results and a dental exam to check the health of your teeth, gums, and jaw joint. From there, the dentist takes impressions or a digital scan of your teeth along with a bite registration that records how your jaw should be positioned, and the appliance is custom-fabricated in a lab. You’ll return for a fitting appointment where the dentist checks comfort and initial positioning, with further adjustments over the following weeks.

Adjusting to and Caring for Your Appliance

It’s common to notice mild jaw soreness, minor bite changes, or extra saliva during the first couple of weeks as your mouth adapts. Most dentists advance the appliance gradually over several follow-up visits rather than all at once, which helps minimize discomfort.

 

  • Clean the appliance daily with a soft brush and lukewarm (not hot) water to avoid warping it
  • Store it in its case when not in use to protect it from damage
  • Bring it to dental checkups so your dentist can check for wear
  • Replace it as recommended, typically every couple of years or sooner if it’s cracked or no longer fits snugly

Insurance Coverage and Cost Considerations

Coverage for oral appliance therapy varies by plan and often depends on having a documented sleep study and physician referral on file. Some extended health plans cover it under dental benefits, others under a separate sleep apnea category – it’s worth confirming with your provider before treatment starts, along with whether your dental office offers direct billing.

Follow-Up Care and Monitoring Treatment Success

Fitting the appliance isn’t the end of treatment – a follow-up sleep study is usually recommended once you’ve been wearing it consistently, to confirm it’s actually reducing apnea events and not just quieting the snoring. Your dentist will also want to see you periodically to check for bite changes or jaw joint discomfort that can develop with long-term wear.

 

Staying in touch with both your dentist and your sleep physician over time is what turns oral appliance therapy from a one-time fitting into an effective, ongoing treatment.
