Canonical: https://sleepclinicdirectory.com/articles/sleep-apnea-treatment-options Last updated: 2026-10-30 ## Key clinical takeaways - Continuous positive airway pressure delivers filtered air through a mask to keep the upper airway open. - A mandibular advancement device (MAD) is a custom oral appliance that holds the lower jaw forward, enlarging the airway. - Weight loss can reduce OSA severity, especially in people with obesity. - Some people have apnea mainly when sleeping on their back (supine OSA). - Surgery can help when a specific anatomical obstruction is identified. ![CPAP mask, oral appliance and sleep study equipment on a table](https://sleepclinicdirectory.com/images/articles/sleep-apnea-treatment-options.png) *The best treatment is the one that fits the airway, the severity and the patient's life.* **Quick answer:** CPAP is the most effective treatment for moderate-to-severe obstructive sleep apnea. A mandibular advancement device can help selected patients with mild-to-moderate OSA or CPAP intolerance. Weight loss, positional therapy, surgery and hypoglossal nerve stimulation are options for specific cases. Central sleep apnea has a different treatment path. Sleep apnea treatment is not a single decision. It depends on the type of apnea, the severity, the anatomy of the airway, the patient's cardiovascular risk, insurance and what they can actually use every night. The best device on paper is useless if it stays in a drawer. This guide compares the main options for obstructive sleep apnea and explains where each fits. ## CPAP: still the reference standard Continuous positive airway pressure delivers filtered air through a mask to keep the upper airway open. It is the most studied and most effective treatment for moderate-to-severe OSA. It reduces the apnea-hypopnea index, improves daytime sleepiness and may lower cardiovascular risk when used consistently. The challenge is adherence. Masks leak, noses dry out, and the machine can feel intrusive. A good setup — the right mask, humidification, a trial of several interfaces and follow-up — makes a bigger difference than the brand of the machine. See [CPAP therapy: getting started](https://sleepclinicdirectory.com/articles/cpap-therapy-getting-started). CPAP is not a cure. It works on the nights you use it. If you travel or nap, you need a plan. ## Mandibular advancement devices A mandibular advancement device (MAD) is a custom oral appliance that holds the lower jaw forward, enlarging the airway. It is fitted by a dentist trained in sleep medicine, often after a dental and airway assessment. MADs are best for mild-to-moderate OSA, especially in people who cannot tolerate CPAP, and for those with a favorable jaw and dental structure. They can reduce snoring and the AHI, but they are usually less effective than CPAP at severe OSA. Side effects include jaw soreness, tooth movement, bite changes and dry mouth. Long-term dental follow-up is important. A store-bought boil-and-bite device is not the same as a custom appliance. It may be better than nothing for snoring, but it is not a reliable treatment for moderate-to-severe apnea. ## Weight loss and metabolic treatment Weight loss can reduce OSA severity, especially in people with obesity. Even modest loss can help; sustained loss is harder. GLP-1/GIP medications such as tirzepatide are now part of the conversation for patients with OSA and obesity, but they do not replace diagnosis or CPAP for everyone. See [Zepbound for sleep apnea](https://sleepclinicdirectory.com/articles/zepbound-sleep-apnea). Bariatric surgery can produce substantial, durable weight loss and improvement in OSA, but it is a major operation with its own risks. It is not a first-line treatment for mild apnea. ## Positional therapy Some people have apnea mainly when sleeping on their back (supine OSA). Positional therapy uses a device or technique to keep them on their side. It can help selected patients with mild positional OSA, but it is not adequate for severe disease. A simple "tennis ball in a sock" is a folk remedy; commercial positional devices are more comfortable. Confirm with a sleep study that the apnea is truly positional before relying on it. ## Surgery Surgery can help when a specific anatomical obstruction is identified. Options include tonsillectomy (especially in children), nasal surgery for obstruction, uvulopalatopharyngoplasty (UPPP), jaw advancement surgery and tongue-base procedures. Results vary, and surgery is not a guaranteed cure. Maxillomandibular advancement is a major operation with good outcomes in selected patients but significant recovery and risk. It is usually reserved for CPAP failure or craniofacial anatomy that fits the procedure. ## Hypoglossal nerve stimulation Hypoglossal nerve stimulation (HNS) uses an implanted device to stimulate the nerve that controls the tongue, opening the airway during sleep. It is an option for selected adults with moderate-to-severe OSA who cannot tolerate CPAP and meet specific anatomical and trial criteria. HNS is not for everyone. It requires surgery, a drug-induced sleep endoscopy or other evaluation, and a commitment to follow-up. It can be effective in the right patient, but it is not a simple alternative to CPAP for all comers. ## Central sleep apnea is different The options above are for obstructive sleep apnea. Central sleep apnea treatment depends on the cause and may involve ASV, bi-level ventilation, oxygen or treatment of heart failure. ASV is contraindicated in some patients with heart failure and reduced ejection fraction. See [central sleep apnea](https://sleepclinicdirectory.com/articles/central-sleep-apnea). ## How to choose Ask your sleep clinician: 1. Is my apnea obstructive, central or mixed? 2. How severe is it, and what is my oxygen level? 3. Do I have cardiovascular risk that changes the urgency? 4. What are the realistic success rates for each option in my anatomy? 5. What follow-up will confirm that the treatment is working? A repeat sleep study or home test may be needed after surgery, a major weight change or a device change. Symptoms alone are not a reliable measure of control. If you need to arrange testing, [find a sleep study near you](https://sleepclinicdirectory.com/sleep-study-near-me) or [find a sleep doctor](https://sleepclinicdirectory.com/sleep-doctor-near-me). ## Frequently Asked Questions ### Is CPAP the best treatment for sleep apnea? For moderate-to-severe obstructive sleep apnea, CPAP is the most effective and best-studied treatment. The best treatment for you depends on severity, anatomy, cardiovascular risk and adherence. ### Can a mouth guard cure sleep apnea? A custom mandibular advancement device can reduce events in selected patients, especially mild-to-moderate OSA, but it is not a cure. It requires dental follow-up and may not control severe apnea. ### What is the success rate of sleep apnea surgery? It varies widely by procedure and patient selection. Some surgeries improve symptoms and AHI, but none is guaranteed. Surgery is usually considered when CPAP and other options are inadequate or unacceptable. ### Is hypoglossal nerve stimulation better than CPAP? Not generally. HNS is an option for selected CPAP-intolerant patients who meet criteria. CPAP remains the first-line treatment for most moderate-to-severe OSA. ### Can I stop treatment if I lose weight? Only after a repeat sleep study and a clinician's review. Weight loss can improve OSA, but it does not always eliminate it, and symptoms can return with weight regain. ## Final Thoughts The treatment menu is broad because sleep apnea is not one problem. CPAP remains the reference standard, oral appliances help a subset, and surgery or nerve stimulation can rescue selected patients. The right choice starts with a clear diagnosis and a conversation about what you will actually use. *This article is general information, not medical advice.* ## Related reading - [CPAP therapy: getting started](https://sleepclinicdirectory.com/articles/cpap-therapy-getting-started) - [Central sleep apnea](https://sleepclinicdirectory.com/articles/central-sleep-apnea) - [Home sleep test vs in-lab study](https://sleepclinicdirectory.com/articles/home-sleep-test-vs-in-lab-study) ## Related guides in this series - [Sleep Clinics in Spring, TX: How to Choose One](https://sleepclinicdirectory.com/articles/sleep-clinics-spring-tx) — Spring, TX has four sleep clinics listed in the directory, with services ranging from insomnia treatment to home sleep tests.
