Are custom oral appliances expensive?

They are more expensive than over-the-counter versions, but they are often covered by medical insurance (not dental insurance) when used to treat diagnosed sleep apnea.

Can I use an oral appliance if I wear dentures?

It depends on the type of dentures and the health of the jaw. A specialized dentist can determine if a different type of device, like a Tongue Retaining Device, might be more appropriate.

How long do the appliances last?

With proper care and cleaning, a high-quality medical oral appliance typically lasts between 3 and 5 years.

Oral Appliances for Sleep Apnea | whataresleepdisorders.com

For individuals with mild-to-moderate obstructive sleep apnea (OSA) or those who cannot tolerate CPAP therapy, oral appliance therapy (OAT) is an effective and comfortable alternative. These devices are worn only during sleep and work by physically modifying the position of the structures in your mouth.

Unlike over-the-counter 'anti-snoring' mouthguards, medical-grade oral appliances are custom-fitted by a dentist specialized in sleep medicine. They are designed to be durable, adjustable, and significantly more effective than generic alternatives.

How Oral Appliances Work

The most common type of oral appliance is the Mandibular Advancement Device (MAD). It looks similar to a sports mouthguard or an orthodontic retainer. It works by gently pushing the lower jaw (mandible) forward, which in turn pulls the tongue forward and tightens the soft tissues in the back of the throat.

This mechanical adjustment increases the size of the upper airway and reduces the air turbulence that causes snoring. By keeping the airway open, it prevents the collapses that cause apneas and allows for steady, uninterrupted breathing.

Candidacy and Selection

Oral appliances are most effective for patients with mild-to-moderate OSA, particularly those whose apnea is worse when sleeping on their back. They are also an excellent option for 'primary snorers'—those who snore loudly but do not have full sleep apnea.

A sleep physician must first diagnose the apnea and then refer the patient to a qualified dentist. The dentist will evaluate the patient's teeth, jaw joint (TMJ), and oral health to ensure they can support the appliance without long-term damage.

Benefits of Oral Appliance Therapy

The primary benefit of OAT is higher compliance. Many patients find it much easier to use an oral appliance consistently compared to a CPAP mask and hose. The devices are also completely silent, require no electricity, and are extremely easy to pack for travel.

Clinical studies have shown that while CPAP may be more 'efficient' at reducing the number of apneas, the overall health outcomes for oral appliances are often similar because patients are more likely to use them for the entire night.

Potential Side Effects

Initially, patients may experience tooth soreness, jaw muscle fatigue, or increased salivation. Most of these issues resolve within a few weeks as the mouth adjusts. Over time, there is a risk of slight shifts in the bite or tooth position.

To mitigate these risks, specialized dentists provide 'morning repositioners' to help the jaw return to its normal alignment after wearing the device all night. Regular follow-up appointments are essential to monitor oral health and adjust the device for maximum effectiveness.
