Mandibular advancement device: Your effective solution for snoring and sleep apnea

Snoring can be really annoying — for you and your loved ones. Sometimes there’s more behind it, like sleep apnea. This is a serious breathing disorder. But don’t worry, a mandibular advancement device can help. But how exactly does it work, and what types are available? In this article, you’ll learn everything you need to know about oral appliances for snoring and how you can benefit from a custom-fitted solution.

What is a mandibular advancement device?

A mandibular advancement device, also known as a protrusion splint or anti-snoring appliance, is a medical device used in modern dentistry to treat snoring and mild to moderate sleep apnea. It holds your lower jaw slightly forward, keeping your airway open during sleep. This helps significantly reduce snoring sounds and improves your oxygen supply.

Snoring occurs when the muscles in the throat relax and the airway narrows. This causes the tissue to vibrate — creating the typical snoring sound. A mandibular advancement device can address this directly and effectively prevent the constriction.

How does a mandibular advancement device work?

The mandibular advancement device works mechanically: it holds your lower jaw in a stable, slightly forward position. This keeps the airway open, prevents the tongue from falling back, and allows unobstructed airflow. The result: less or no snoring at all.

A custom-fitted mandibular advancement device consists of two parts — one appliance for the upper jaw and one for the lower jaw. These are connected with a special mechanism that allows precise positioning. The major advantage of a custom-made appliance: it fits perfectly, offers high comfort, and maximum effectiveness.

Regular adjustments are important to ensure the appliance works optimally and causes no discomfort. Your orthodontist at JUST KFO in Cologne will provide comprehensive guidance on this.

When is snoring dangerous?

Snoring can be more than just annoying — sometimes it’s a sign of serious health problems. Obstructive sleep apnea in particular is a risk factor for high blood pressure, heart disease, and daytime fatigue. Typical symptoms include:

• Breathing pauses during sleep

• Increased daytime fatigue

• Concentration problems

• Morning headaches

If these symptoms occur, you should definitely consult a specialist. A custom-fitted mandibular advancement device can be a simple and effective solution to keep your airway open and improve your sleep quality.

Cost of a mandibular advancement device

The cost of a mandibular advancement device varies depending on the model, material, and individual customization. Typically, prices range between 1.000 and 2.200 Euro. Additional costs may apply for regular checkups and adjustments. A comparison of costs for all types of oral appliances — from aligners to retainers — can be found in the article What Does an Oral Appliance Cost?.

High-quality, individually fabricated mandibular advancement devices offer the best wearing comfort and a long lifespan. Your orthodontist at JUST KFO will provide comprehensive consultation and prepare an individualized cost estimate.

Does health insurance cover the cost?

Whether health insurance covers the cost of a mandibular advancement device depends on the diagnosis. For simple snoring without sleep apnea, the device is usually not a covered benefit. However, if sleep apnea is diagnosed and other therapies have been unsuccessful, coverage may be possible. Your treating physician can advise you on this.

Risks and side effects of a mandibular advancement device

As with any medical treatment, side effects can occur when using a mandibular advancement device. However, these are usually harmless and disappear after a short adjustment period. Possible side effects include:

• Mild jaw pain or muscle tension

• Increased salivation or dry mouth

• In rare cases, minimal tooth movement

Through regular checkups with your orthodontist, these effects can be detected early and corrected by adjusting the appliance.

Can a mandibular advancement device be swallowed during sleep?

This concern is unfounded. Modern mandibular advancement devices are individually fitted to your jaw and have a precise shape. They fit securely and firmly, so swallowing is impossible.

Which mandibular advancement device is right for you

A mandibular advancement device can be an effective solution for reducing snoring and sleep apnea. For it to work optimally, individual customization is crucial.

At JUST KFO in Cologne, we support you with expertise and experience — all details on the process, fitting, and costs can be found on our page about mandibular advancement device treatment in Cologne. The diagnosis and treatment of patients with sleep-related breathing disorders always takes place in collaboration with a specially trained sleep medicine physician.

Frequently asked questions about mandibular advancement devices

How quickly does a mandibular advancement device work?

Many users notice improvement within the first few nights. However, it may take several weeks for the lower jaw to adjust to the slightly advanced position and for the optimal setting to be found. Readjustment is completely normal.

What does a mandibular advancement device cost and does health insurance pay?

For private patients, costs typically range from approximately 1.000 to 2.200 Euro, depending on the model and adjustment. For snoring without sleep apnea, the appliance is usually not covered by statutory health insurance. In cases of medically diagnosed obstructive sleep apnea, it may be covered under certain conditions as a second-line therapy if CPAP therapy cannot be successfully used.

How do I properly care for my mandibular advancement device?

Clean the appliance daily with lukewarm water and a soft toothbrush. You should avoid hot water, as it can deform the material. During regular follow-up appointments, we check the fit and condition.

Can I swallow the appliance in my sleep?

A custom-made mandibular advancement device fits securely on the dental arches and typically cannot come loose or be swallowed during sleep. This is precisely one advantage over prefabricated models for self-fitting.

When is snoring a case for a physician rather than an appliance?

If obstructive sleep apnea is suspected—for example, due to breathing pauses, severe daytime sleepiness, or morning headaches—the first step should be a sleep medicine evaluation, not going directly for an appliance. Only after a confirmed diagnosis can it be determined whether a mandibular advancement device is the appropriate therapy. We work interdisciplinarily with ENT and sleep medicine specialists for this purpose.
