Question 1

What is oral appliance therapy?

Accepted Answer

Oral appliance therapy is a non-surgical treatment for sleep-disordered breathing using a custom-fitted mandibular advancement device worn during sleep. The appliance gently repositions the lower jaw and tongue to keep the airway open. These FDA-cleared devices are a proven CPAP alternative for mild to moderate obstructive sleep apnea and are also effective for snoring reduction.

Question 2

Can an oral appliance treat sleep apnea?

Accepted Answer

Yes. Oral appliances are FDA-cleared for treating mild to moderate obstructive sleep apnea and are an accepted alternative for severe OSA when CPAP is not tolerated. Clinical studies show custom oral appliances can significantly reduce the apnea-hypopnea index. Effectiveness should be confirmed with a follow-up sleep study.

Question 3

Can an oral appliance reduce snoring?

Accepted Answer

Yes. Snoring is caused by tissue vibration in a narrowed airway. By advancing the mandible and increasing airway space, an oral appliance reduces or eliminates snoring in most patients. Even individuals without diagnosed sleep apnea but with primary snoring may benefit from a custom oral appliance.

Question 4

Is oral appliance therapy better than CPAP?

Accepted Answer

There is no universal better option. CPAP is highly effective across all severity levels but many patients cannot tolerate the mask and pressure. Oral appliances offer superior comfort, portability, and adherence, with research showing comparable effectiveness for mild to moderate OSA. The right choice depends on severity, anatomy, tolerance, and lifestyle. A qualified provider can help determine the best fit.

Question 5

What is Inspire therapy?

Accepted Answer

Inspire is a surgically implanted hypoglossal nerve stimulation device. It delivers an electrical impulse to the nerve controlling the tongue, moving it forward during sleep to maintain airway patency. It is indicated for moderate to severe OSA in adults who cannot tolerate CPAP and meet specific BMI and anatomical criteria.

Question 6

How does oral appliance therapy compare with Inspire?

Accepted Answer

Oral appliance therapy is entirely non-surgical, removable, and reversible. Inspire requires surgery and involves a permanent implant with a battery that eventually needs replacement. Oral appliances are adjustable at any time; Inspire settings are programmed externally but the device remains implanted. Oral appliances are typically first-line for mild to moderate OSA, while Inspire is reserved for moderate to severe OSA in CPAP-intolerant patients who meet specific criteria.

Question 7

Who may be a candidate for oral appliance therapy?

Accepted Answer

Adults with mild to moderate obstructive sleep apnea, patients who cannot tolerate CPAP, individuals with primary snoring, and frequent travelers may be candidates. Eligibility requires a diagnostic sleep study, dental examination, and medical evaluation. People should be evaluated by qualified providers — not everyone qualifies, and severe OSA may require CPAP or other therapies.

Question 8

Can dentists provide oral appliance therapy?

Accepted Answer

Yes, dentists trained in dental sleep medicine can fabricate and manage oral appliances. However, diagnosis of sleep apnea must come from a physician or sleep specialist based on a sleep study. The ideal model is collaborative — a sleep physician diagnoses and oversees medical management, while a qualified dental provider handles appliance fabrication, fitting, and follow-up.

Question 9

Do I still need a sleep physician?

Accepted Answer

Yes. A sleep physician or qualified medical provider should be involved in diagnosis, treatment planning, and follow-up. The dentist manages the device; the physician manages the sleep disorder. Follow-up sleep studies to verify treatment effectiveness are typically ordered by the physician.

Question 10

Does oral appliance therapy require a sleep study?

Accepted Answer

Yes. A diagnostic sleep study (in-lab polysomnography or home sleep test) is required to diagnose sleep apnea and determine severity before treatment. A follow-up sleep study with the appliance in place is recommended to confirm that the oral appliance is effectively reducing apneas and improving oxygen saturation.

Question 11

Is oral appliance therapy comfortable?

Accepted Answer

Most patients find oral appliances comfortable, especially compared to CPAP masks. Modern custom appliances are made from thin, lightweight materials and are individually fitted. There is an adjustment period, but discomfort is typically mild and temporary. The provider can adjust the appliance if needed.

Question 12

How long does it take to adjust to an oral appliance?

Accepted Answer

Most patients adjust within one to two weeks. During the first few nights, increased salivation or a feeling of fullness in the mouth is common and typically resolves quickly. The provider gradually titrates (adjusts) jaw advancement over follow-up visits to optimize effectiveness while maintaining comfort.

Question 13

Can oral appliances cause jaw pain?

Accepted Answer

Some patients experience mild, temporary jaw soreness or muscle discomfort, especially during the first weeks or after advancement adjustments. This usually resolves as the muscles adapt. If jaw pain persists, the provider can modify the appliance. Patients with pre-existing TMJ conditions should discuss this before starting treatment.

Question 14

Can oral appliances affect teeth?

Accepted Answer

Over long-term use, some patients may experience minor tooth movement or bite changes. Regular follow-up with the dental provider helps monitor and manage these effects. Most changes are minimal and can be addressed if caught early. Patients with insufficient healthy teeth or severe periodontal disease may not be ideal candidates.

Question 15

How is oral appliance therapy treatment success measured?

Accepted Answer

Treatment success is measured through a follow-up sleep study to confirm reduction in the apnea-hypopnea index, improvement in oxygen saturation, and resolution of symptoms such as snoring and daytime sleepiness. Subjective improvements in sleep quality and daytime function are also assessed. Ongoing follow-up ensures continued effectiveness.
