What Dental Devices Are Used for Sleep Apnea?

At Alameda Dental in Aurora, CO, we regularly meet people who struggle with snoring, restless sleep, or a diagnosis of obstructive sleep apnea. These issues don't just disturb nights—they can drain daytime energy and affect overall wellness. When patients ask us about dental devices for sleep apnea, we want them to have a clear picture of how these appliances work, who they may help, and what the treatment journey involves. This article explains the oral appliances dentists use for sleep-disordered breathing, how they compare to other therapies, and what you can expect when you visit our office at 14591 E Alameda Ave.

01 / Understanding obstructive sleep apneaUnderstanding obstructive sleep apnea

Obstructive sleep apnea (OSA) happens when the soft tissues at the back of the throat relax too much during sleep and temporarily block the airway. This leads to repeated pauses in breathing that can last ten seconds or longer. The brain then nudges the body awake to resume airflow, often without full consciousness. Over the course of a night, these disruptions can occur dozens of times per hour, fragmenting sleep and lowering blood oxygen levels. Common signs include loud snoring, witnessed gasping or choking, morning headaches, and excessive daytime sleepiness. A physician typically diagnoses OSA using a sleep study, which measures the apnea-hypopnea index (AHI) and classifies the severity as mild, moderate, or severe. At Alameda Dental, we do not diagnose sleep apnea on our own; we work alongside your medical team. Once a diagnosis is established, we can discuss whether an oral appliance is a suitable part of your care plan.

02 / When oral appliances are appropriateWhen oral appliances are appropriate

Oral appliance therapy is most often recommended for people with mild to moderate OSA, or for those with severe OSA who cannot tolerate positive airway pressure (CPAP). CPAP is highly effective, but some people find the mask uncomfortable, the noise disruptive, or the pressure difficult to adjust to. In those cases, a dental device may be an alternative. We also consider appliances for individuals with primary snoring (without significant apnea) after other causes have been ruled out. The decision hinges on your sleep study results, the anatomy of your airway and jaw, your dental health, and your personal preferences. Our team reviews these factors carefully and coordinates with your sleep physician to make sure the chosen therapy aligns with your overall health goals.

03 / Types of dental devices for sleep apneaTypes of dental devices for sleep apnea

Dentists use several kinds of oral appliances to manage sleep-disordered breathing. They work by repositioning the jaw or tongue to keep the airway more open during sleep. The main categories are mandibular advancement devices, tongue-retaining appliances, and—less commonly as a standalone treatment—guards that address tooth grinding while offering some airway benefit.

Mandibular advancement devices (MADs)

Mandibular advancement devices are the most frequently prescribed oral appliances for OSA. They look similar to a double-sided mouthguard and fit over the upper and lower teeth. Small connectors between the two trays hold the lower jaw slightly forward. This forward position tugs the tongue and soft palate away from the back of the throat, widening the airway and making it less likely to collapse.

At Alameda Dental, we take precise impressions of your teeth and a bite registration to fabricate a custom MAD. Many appliances allow for incremental adjustment—tiny screws or bands that let us gradually increase the amount of jaw advancement. This titration is important: move the jaw forward too little and apnea may persist; move it too much and the jaw joint or teeth may become sore. We work with you to find the sweet spot where breathing improves without discomfort. Follow-up sleep testing, often ordered by your physician, helps confirm that the device is working as intended.

Tongue-retaining devices

For some people, the tongue is the main source of airway obstruction. A tongue-retaining appliance holds the tongue forward using gentle suction or a soft bulb that sits between the lips and teeth. This approach doesn't require tooth contact, so it can be a good option if you have several missing teeth, extensive dental work, or a jaw that doesn't move well.

These devices can feel a bit unusual at first. Increased salivation or mild tongue soreness is common, but most people adapt within a couple of weeks. We discuss the fit and care thoroughly, and we monitor how you're adjusting during follow-up visits.

Teeth grinding guards and sleep apnea

Bruxism—the habit of clenching or grinding during sleep—frequently coexists with sleep apnea, although the relationship isn't fully understood. A conventional night guard protects tooth enamel from wear but does not reposition the jaw to address airway collapse. Therefore, a standard grinding guard is not a treatment for OSA. However, some hybrid designs combine mandibular advancement with a protective bite surface. If you grind your teeth and have mild sleep apnea, we can talk about whether a dual-purpose appliance makes sense. Otherwise, we treat the two issues as separate but related concerns.

04 / The process at Alameda DentalThe process at Alameda Dental

When you come to our office for a sleep apnea consultation, we start with a conversation. We want to hear about your sleep quality, daytime symptoms, and any previous treatments you've tried. We review your sleep study report and examine your teeth, gums, jaw joints, and oral structures. If an oral appliance seems appropriate, we explain which type we recommend and why. Then we take the impressions and jaw records that the dental lab will use to craft your device. We may also take photographs and basic X-rays to document your starting point.

Once the appliance arrives from the lab, we have a delivery appointment where we ensure it seats comfortably, doesn't rock on the teeth, and doesn't put too much pressure on the gums. We show you how to insert, remove, and clean it. We also schedule a follow-up visit within a few weeks to check for any sore spots, jaw tenderness, or fit issues. Adjustments are normal during this phase. Over the long term, we recommend periodic check-ups—usually annually—to examine the appliance for wear, monitor your bite, and discuss any changes in your sleep or health.

01 / Benefits and limitationsBenefits and limitations

Oral appliances offer several advantages. They are quiet, portable, and don't require electricity. Many people find them more comfortable than a CPAP mask, and partners often report a quieter bedroom. That said, they are not a cure for sleep apnea. They typically reduce the number of breathing interruptions rather than eliminate them entirely. Some people experience temporary jaw stiffness in the morning, minor bite changes, or dry mouth. Over years of use, very slight tooth movement can occur, which is why regular monitoring matters. We weigh these possibilities against the known risks of untreated OSA—such as high blood pressure, heart strain, and daytime fatigue—to help you make an informed choice.

02 / What to expect during follow-up careWhat to expect during follow-up care

An oral appliance is not a "set it and forget it" device. Your needs can change over time. Weight gain or loss, aging, or new medications can influence sleep apnea severity. At your annual visits, we will check the appliance for cracks or worn parts, clean it ultrasonically, and assess your jaw joints and bite alignment. We may recommend a repeat sleep study with the appliance in place to verify that it's still effective. If we notice early signs of tooth shifting, we can usually address them with minor adjustments or a brief course of orthodontic aligners. Should your sleep apnea worsen, we coordinate with your physician to explore whether the appliance settings need to change or whether a different therapy—like returning to CPAP or combining therapies—becomes necessary.

03 / Frequently asked questionsFrequently asked questions

How do I know if I'm a candidate for an oral appliance? The best starting point is a sleep study ordered by your doctor. If you have mild to moderate OSA, or severe OSA and struggle with CPAP, an oral appliance may be an option. Our team will evaluate your dental health and jaw function to determine suitability.

Will the appliance stop my snoring? Many people find that snoring decreases significantly when the airway is kept open. However, snoring can have multiple causes, so results vary. We can't promise complete silence, but improved airflow often leads to noticeable improvement.

Can I use an over-the-counter mouthguard instead? Boil-and-bite devices sold online or in stores are not designed to treat sleep apnea. They lack the precise fit and gradual adjustability of a custom appliance, and they can aggravate jaw joint problems. A professionally fitted device is essential for both safety and effectiveness.

Does insurance cover oral appliance therapy? Medical insurance plans often provide some coverage for oral appliances when prescribed for diagnosed sleep apnea. Coverage details depend on your specific plan. Our team can help with pre-authorization paperwork and explain any out-of-pocket costs before treatment begins.

How long does it take to get used to the device? Adaptation varies. Some people adjust within a few nights; others need a couple of weeks. Saliva flow may temporarily increase, and your jaw muscles might be slightly sore, but these effects typically lessen as your body adapts.

What if I need an MRI or other medical scan? Most oral appliances are metal-free, but always inform the technician about your device. In most cases, you simply remove it before the scan.

Can I combine an oral appliance with CPAP? In some situations, yes. When CPAP alone isn't tolerated at high pressures, wearing an oral appliance can reduce the airway pressure needed, making CPAP easier to accept. This combination therapy requires coordination between your dentist and sleep physician.
