Many people (and their partners) lose sleep due to chronic snoring. Snoring normally occurs when your tongue and tissues in your mouth and throat become too relaxed. Air passing through creates vibrations in the tissue, producing the telltale snoring sound. Snoring can be highly disruptive and may also indicate serious medical conditions.
Snorers often find relief using mouthpieces designed to reduce snoring. These devices, also called mouthguards, fall into two general categories. Mandibular advancement devices, or MADs, fit inside the mouth and push the lower jaw forward to open up your airway. Tongue retaining devices (TRDs) grip the tongue and prevent it from falling into the back of the throat, which commonly causes snoring for back sleepers.
Our Verdict – What’s the Best Anti-Snoring Mouthpiece?
Comfort is key when searching for an anti-snoring mouthpiece, and it can be challenging to find a product that fits your mouth and your needs. We recommend the SnoreRx Plus thanks to its boil-and-bite molding and full lateral adjustment, which allow you to fully customize the fit to your mouth.

Those who don't usually snore provided more general feedback about qualities such as ease of customization and overall comfort. These top picks reflect the collective findings of our testing team.
How to Choose an Anti-Snoring Mouthpiece or Mouthguard
The most important consideration when choosing an anti-snoring mouthpiece (also known as a mouthguard) is whether you prefer the manual jaw advancement of an MAD or the tongue-restraining suction of a TRD. These devices may require an adjustment period as you become acclimated to their feel, especially while trying to sleep.
Most over-the-counter MADs and TRDs sold today cost between $50 and $150 apiece. You should consult your doctor before buying one of these devices to determine which type (if any) will be suitable for you. Medical professionals may also offer tips and advice on models that work best.
Who Should Consider an Anti-Snoring Mouthpiece?
There is no cure for snoring, but the best snoring aids will significantly reduce symptoms. Many snorers benefit from using an anti-snoring mouthpiece. Snoring affects roughly 90 million adults nationwide. For more than one-third of these sleepers, snoring is a chronic – if not nightly – issue.
Snoring usually occurs due to a restricted airflow through the breathing passages. This can happen for different reasons. If your soft palate is relatively thick or hangs somewhat low, then your airway will be narrower and snoring is more likely. Chronic congestion and other nasal problems may also cause snoring. Being overweight or obese can cause extra tissue to accumulate around the airway, as well.
Another common snoring culprit is alcohol. If you drink before going to sleep, your throat may relax a bit too much. This can cause the tongue to fall back into your throat, blocking the airway. The throat muscles may also relax if you are excessively tired or sleep deprived. Additionally, sleeping on your back leaves you most vulnerable to snoring because the tongue is more likely to block the airway.
Over time, chronic snoring can lead to further complications. These include daytime sleepiness and fatigue, mood swings and angry outbursts, difficulty focusing on tasks, and a higher risk of being involved in a vehicular or workplace accident. For those with non-apnea-related snoring issues, MAD and TRD mouthpieces can decrease snoring episodes on a nightly basis. These devices are much more affordable than upper airway surgery and other medical procedures used to treat snoring. Be sure to speak to your doctor before purchasing an MAD or a TRD, or trying one for the first time.
While effective for many, you may find that anti-snoring mouthpieces and mouthguards are not right for you. Some people find these devices uncomfortable, and even painful at times. They may also be ineffective at treating heavy snoring from conditions like obstructive sleep apnea.
How Do Anti-Snoring Mouthpieces Work?
Despite their effectiveness against snoring for many, anti-snoring mouthpieces are fairly simple devices with a small number of individual parts. How they work depends on whether the mouthpiece is an MAD or a TRD.
MADs are the most common type of anti-snoring mouthpiece. Most have thermoplastic material in the upper and lower trays where your teeth are intended to fit. When exposed to boiling water, the thermoplastic will soften and you’ll be able to bite down into both trays, creating a customized mold. Unless the device’s instructions say otherwise, the step-by-step “boil-and-bite” process is as follows.
- Before boiling, try on the mouthpiece by softly biting down onto the thermoplastic in the upper and lower trays. A properly fitting device should come within a couple millimeters of your lips.
- For some devices, you may need to trim the ends of the upper and lower trays in order for the device to properly fit. For others, this step will not be necessary.
- Boil water in a pot on your stovetop or in a microwaved cup (depending on what the directions say). Once the water has boiled, place the water’s container on a non-heated surface. Make sure there’s enough water in the container to completely submerge the mouthpiece.
- Submerge the mouthpiece in the boiled water for 30 to 60 seconds, depending on the directions.
- At this point, you may need to place the mouthpiece in cold water for a couple of seconds, but most models will be ready for molding – though you should let the thermoplastic cool off for a moment before biting into it.
- After placing the device in your mouth, bite down firmly with your upper and lower teeth. The thermoplastic should feel warm, but not excessively hot; if the latter, allow it to cool a bit longer. Make sure your tongue is pressing against the roof of your mouth as you do so. This helps to dry off the mouthpiece.
- If your first mold is unsuccessful, repeat these steps. The thermoplastic should soften enough to allow multiple attempts.
Assuming the mold is successful, the MAD will advance your jaw by at least 1mm once it is placed inside the mouth with your teeth in the upper and lower trays. Customizable models can be manually adjusted in increments of 1mm to ensure a comfortable advancement level. Other MAD models automatically adjust using a flexible hinge that adapts to the shape of your jaw and mouth. By advancing the jaw forward, MADs can widen your breathing passages to allow easier air passage and reduce the risk of snoring.
TRDs are a bit more straightforward. Most TRDs resemble the pacifiers used by babies and infants. They are outfitted with flanges that rest against the inner folds of your upper and lower lip, along with an opening where the tongue fits. This opening is fairly narrow to promote suction, which keeps the tongue near the front of the mouth and away from the back of your throat. TRDs are normally designed for universal fit, so you won’t need to follow boil-and-bite instructions or customize their settings.
Types of Anti-Snoring Mouthpieces: MADs vs. TRDs
Now that we’ve established how MADs and TRDs work, let’s see how these anti-snoring mouthpieces compare to one another. MADs and TRDs both have the potential to reduce snoring episodes for sleepers. However, each device carries different advantages and disadvantages for sleepers.
Anti-Snoring Mouthguard Considerations
MADs and TRDs achieve the same outcome – less snoring, in most cases – using completely different means and mechanisms. As you determine which type of anti-snoring mouthpiece will work best, consider the following factors.
- Customization: MADs offer more customization options. Most of these mouthpieces are boil-and-bite models with trays containing thermoplastic, allowing you to create a custom mold for your teeth. TRDs do not require or offer this level of customization. Most are universal fit designs, but some models come in multiple sizes to accommodate different sleepers.
- Quality Material: Most MADs and TRDs are made from silicone resin, plastic, or a combination of both of these materials. Boil-and-bite MADs may be made entirely of moldable thermoplastic, or just contain layers of this material in their upper and lower trays. Most anti-snoring mouthpieces made today do not contain latex or BPA plastic. Most devices will last between 6 months and 2 years before a replacement is needed.
- Comfort: Some sleepers prefer the jaw-advancing feel of an MAD over the tongue-retaining suction of a TRD. For others, the opposite is true. You may want to consider both in order to determine which device is more comfortable – in which case, models with sleep trials are probably the best bet. The bottom line: ask your doctor about MADs and TRDs to learn about your best options, and then go from there.
- Adjustability: With some MADs, you’ll be able to adjust how far the device advances your jaw. These devices can usually be adjusted in 1mm increments. Alternatively, the other MADs cannot be manually adjusted. These devices often feature hinge mechanisms that automatically adjust to the users mouth. TRDs, by design, cannot be adjusted.
- Ease of Cleaning: For best results, we recommend rinsing your anti-snoring mouthpiece in hot water after each use. If you use an MAD, you should regularly scrub the upper and lower trays to prevent bacterial buildup. Some brands offer proprietary cleaning solutions for their MADs. Toothpaste and a toothbrush may also work. If you use a TRD, be sure to clean the interior of the tongue opening. Many anti-snoring mouthpieces come with protective cases; if not, make sure the device is stored in a clean environment when not in use.
- Prescription Requirements: Many anti-snoring mouthpieces are available over the counter. For some devices, you’ll need approval from your doctor or dentist and a prescription. Most prescription anti-snoring appliances are MADs custom-fitted for your upper and lower teeth using dental impressions. You’ll obtain the device through your dentist, and visit for routine checkups to ensure the mouthpiece fits and works properly.
How Expensive Are Anti-Snoring Mouthguards?
Anti-snoring mouthpieces typically cost between $50 and $150 apiece. MADs are a bit more expensive, with an average price range of $75 to $150 per device. Most TRDs cost $100 or less. Free shipping may or may not be available, depending on the manufacturer’s delivery policy, but full refunds are usually granted if returns are allowed. Some brands also offer their mouthguards at a discounted rate if you purchase two or more at once.
$50 to $150 might sound expensive for a device that will, in all likelihood, need to be replaced within two years. However, anti-snoring mouthpieces cost much less than upper airway surgery and other medical procedures intended to treat snoring symptoms.
Other Important Concerns About Anti-Snoring Mouthguards
Are they safe for everyone?
Anti-snoring mouthguards are generally considered safe, but you should always consult your doctor before trying one for the first time.
Because they physically advance the jaw forward, MADs can lead to temporomandibular joint (TMJ) disorder, which is characterized by pain in the jaw and its surrounding muscles. MADs and TRDs may also cause pain and irritation to the teeth and gums, especially if the device is not custom molded.
It’s imperative to keep your anti-snoring mouthpiece clean. Sterilize with hot water after each use and clean the device regularly to prevent the buildup of harmful bacteria.
Before purchasing a device, carefully research the top models on your list to see if there have been any known defects or safety issues associated with those products. You can also reach out to customer service personnel to inquire about potential safety concerns.
How important is certification and what should I look for?
Under the U.S. Food and Drug Administration (FDA), MADs, TRDs, and other “intraoral devices for snoring and/or sleep apnea” are considered Class II medical devices. This means they present some risk to users because they come in direct contact with the body. As such, the FDA regulates the sale and distribution of these devices. Mouthpieces must be thoroughly tested and proven to be effective before the FDA will clear them for sale. Any device you buy should carry a “cleared by FDA” label.
Do I need a prescription?
Most anti-snoring mouthpieces can be sold over the counter and do not require a prescription. However, you will need a prescription for certain MAD and TRD models, as well as some advanced custom mouthpieces. Prescription requirements, if any, will typically be listed on the online product pages for these devices.
How does custom fitting work?
Most MAD mouthpieces are designed for boil-and-bite customization. Simply submerge the device in boiled water to soften the thermoplastic in its upper and lower trays, then remove, cool, and bite down on both thermoplastic layers. (Specific instructions vary by model.)
For more expensive custom mouthpieces, you may be asked to make a thermoplastic mold at home and mail the sample to the manufacturer, who will then produce a device custom-fitted to your teeth and jaw.
Some MADs use hinges and other mechanisms to automatically adjust to your mouth, so customization is not needed. Since TRDs have a one-size-fits-all design, these devices are generally not customizable.
Can I wear it with dentures?
If you wear dentures, you should avoid using MAD mouthguards. These devices physically move the jaw forward. In doing so, they can interfere with dentures – and in some cases, dislodge them. MADs are not recommended for people who have dental implants or loose teeth, either. TRDs, on the other hand, do not mold to the teeth and are perfectly denture-friendly (though you should first check with your doctor to make sure these devices are right for you).
Do mouthguards prevent bruxism (teeth grinding)?
MADs can prevent, or at least minimize, nighttime teeth grinding. These devices have upper and lower trays to hold and separate the teeth. Assuming the device is properly fitted, it will keep your upper and lower teeth in place and prevent them from coming into contact with one another.
TRDs do not separate the teeth, and there is no evidence they reduce nighttime teeth grinding.
How do I clean my mouthpiece?
Cleaning instructions vary by model, but you’ll want to sterilize the mouthpiece with hot water after each use. Regularly scrub the device with a cleaning solution to prevent bacterial buildup. You’ll also want to store the mouthpiece in your bathroom cabinet, or another relatively cool place where it won’t be exposed to excessive heat or moisture. Many MAD and TRD manufacturers offer a protective case for their devices.
Do mouthguard manufacturers offer returns? What about warranties?
Anti-snoring mouthpieces often come with a sleep trial of 30 to 60 nights. This allows you to use the device for at least 1 month before deciding whether to keep it or return it for a refund. Shipping charges are usually non-refundable.
Warranties are less common, but some MAD and TRD models are backed by some sort of manufacturer’s guarantee. In most cases, the warranty will cover the device for up to 1 year.
Additional Snoring Solutions and Products
MAD and TRD mouthpieces can be very effective for some sleepers, but these devices may not be right for you – especially if you experience severe chronic snoring. Other treatment options for snoring include the following:
CPAP, BiPAP, and APAP
Sleep apnea is a condition characterized by temporary loss of breath during the night, as well as heavy snoring. Obstructive sleep apnea (OSA) is caused by a physical obstacle blocking the airway, such as the tongue or abnormal tissue buildup, while central sleep apnea (CSA) occurs when the brain cannot transmit signals to muscles that promote breathing.
For people with sleep apnea, positive air pressure (PAP) therapy can reduce the frequency and severity of their nighttime episodes. This therapy involves a machine that draws in outside air using a fan, humidifies and pressurizes the air, and then delivers it to the user through a connective hose and a face mask that covers the mouth and/or nostrils. There are three common types of PAP therapy.
- During continuous positive air pressure (CPAP) therapy, the machine delivers air to its user at one prescribed pressure rate. CPAP is most effective at treating OSA.
- For bi-level positive air pressure (BiPAP) therapy, the pressure toggles between a lower rate for inhalation and a higher rate for exhalation, which can make breathing easier for some people.
- Unlike the other two, automatic positive air pressure (APAP) does not follow a fixed pressure schedule. Instead, the machine adjusts pressure levels based on the user’s breathing patterns. APAP can be effective for both OSA and CSA.
PAP therapy machines, humidifiers, and face masks all require a doctor’s prescription. Consult your physician to learn more if you experience sleep apnea symptoms.
MADs and TRDs are not the only devices you can use to combat snoring. Another example is Provent, a device primarily used to treat sleep apnea symptoms. Provent consists of two air filters placed inside each nostril. This relatively non-invasive device may reduce snoring episodes by a significant extent, but you’ll need a doctor’s prescription to purchase Provent.
For more severe cases of snoring, a palatal lift prosthesis may be another option. These prostheses are used to treat palatopharyngeal incompetence, a condition characterized by difficulty closing the nasal passages when speaking or swallowing. This can lead to obstructive sleep apnea, and with it, chronic snoring. As the name implies, the prosthesis elevates the soft palate to widen the airway and promote better circulation. You’ll need to undergo a medical procedure to have the prosthesis installed, so this may not be your most cost-effective option.
According to the Mayo Clinic, serious snoring may necessitate a surgical procedure. Several procedures can be used to mitigate snoring symptoms. These include uvulopalatopharyngoplasty, during which surgeons remove tissue from the back of your throat to broaden the airway. A similar procedure, radiofrequency tissue ablation, involves a low-intensity signal that decreases tissue around the palate, throat, and tongue. A third option is maxillomandibular advancement surgery, which permanently moves the upper and lower jaws.
Medical researchers continue to discover new treatment methods. One of the more recent innovations is hypoglossal nerve stimulation. For this procedure, surgeons essentially reprogram the nerves that control your tongue’s movements in order to prevent airway blockage.
Surgery can be very expensive, even with health insurance. You should consider any of these procedures as a last resort for snoring treatment.
Pillow Loft and Adjustable Beds
Back sleepers are more susceptible to snoring than those who use other sleep positions because the tongue is likely to fall into the back of the throat and block the airway. For some back sleepers, more pillow loft (or thickness) is needed to elevate the head and keep the tongue closer to the front of the mouth. If your head tends to fall too far back on your pillow, then you should consider a thicker pillow – or a different sleep position.
Adjustable beds can also be beneficial to snoring back sleepers. These beds can be raised or lowered at the head and foot, allowing you to sleep with your head elevated while the rest of your body lies flush with the bed. The downside: adjustable beds can be quite expensive.
You may experience less snoring by changing your daily and nightly routines. Losing weight can reduce snoring by a significant extent, as being obese or overweight are considered major risk factors. Quitting smoking and cutting down on alcohol consumption – especially before bedtime – can also help you cut down on snoring episodes.
If you experience chronic snoring and normally sleep on your back, then you should consider the side position. The tongue is less likely to fall into the back of the throat while you’re lying on your side. You can also prevent airway blockage by sleeping on your stomach, but this position is associated with more aches and pains, and is generally discouraged.
Lastly, the trick to less snoring might be getting more sleep. If you go to bed feeling sleep deprived, the muscles around your throat will relax more during the night and the potential for airway blockage will be much higher. Most adults should sleep at least 7 to 9 hours each night, including on the weekends.
Frequently Asked Questions
The best anti-snoring mouthpiece (also known as a mouthguard) depends on your personal preferences. Most mouthguards fall into one of two categories. Mandibular advancement devices (MADs) have upper and lower trays designed to fit around your teeth and physically move the jaw forward, which expands the breathing passage and allows more air to pass through.
MADs are often “boil-and-bite” mouthguards made of thermoplastic. Owners boil them in water, then bite into the thermoplastic to create a customized impression. After the material cools and hardens, the MAD will be ready to use. Other MADs are specifically created using a customer’s dental impressions, and some can later be adjusted for advancement level.
The customized nature of MADs makes them very effective. They also allow sleepers to breathe through their mouths, and a lack of protruding parts means these mouthguards are compatible with any sleep position. However, MADs are associated with more jaw pain and stiffness, drooling, and other negative side effects. Many people – including those with braces or dentures – won’t be able to use them, and a prescription is normally required.
The other type of anti-snoring mouthguard is the tongue-retaining device (TRD), which are designed with flanges that rest against your lips and a small compartment for the tongue. The compartment essentially suctions the tongue in place, preventing it from falling back into the throat – a common source of heavy snoring.
TRDs are lighter and easier to wear than MADs, and not associated with as many adverse effects. They also won’t interfere with dentures or braces, and most don’t require a prescription. However, TRDs usually can’t be customized, and instead have a “one-size-fits-all” design that will serve some sleepers better than others. They can also restrict breathing by forming a seal around the mouth.
Mouthguards can be very effective for treating heavy snoring, especially custom-fitted models. However, additional remedies can also be helpful. For instance, sleeping on your back and consuming alcohol before bed are two common reasons why people snore. Avoiding the back position and refraining for drinks in the hours before going to sleep can further alleviate snoring if you use a mouthguard.
Some people snore due to a medical condition known as obstructive sleep apnea (OSA), which not only promotes heavy snoring but also causes people to wake up choking or gasping for air throughout the night. While mouthguards can mitigate the snoring issue, a CPAP or BiPAP machine is usually the best form of treatment for people with OSA.
Some people with obstructive sleep apnea (OSA) benefit from using an anti-snoring mouthguard. CPAP therapy is widely considered the most effective treatment option for OSA, but a mouthguard can improve airflow and reduce the snoring associated with this sleep disorder. If you have been diagnosed with OSA and CPAP therapy has not been effective, talk to your doctor about anti-snoring mouthguards and other alternative treatments.
While snoring mouthguards don’t move your teeth the way braces do, they can change the position of your jaw while you use them. MAD-style mouthguards physically advance your jaw forward to create more room for air to pass through your breathing passages. This can cause discomfort in some sleepers and can lead to TMJ or other irritations. People with dentures, cracked teeth, dental implants, or braces should not use MADs unless directed to do so by a physician.
TRD-style mouthguards create more breathing room by restricting tongue movement rather than altering the position of your jaw. As a result, TRDs are less likely to cause jaw or tooth discomfort. Consult with your doctor before choosing an anti-snoring mouthguard.
