About 45 percent of people1 snore at least occasionally, while about 25 percent snore regularly. This loud noise, caused by the vibration of tissues in the back of the throat, can lead to sleep deprivation and even an increased risk for things like obesity, diabetes, and heart disease – not just for the person snoring, but their bed partner as well2.
So what are you supposed to do if you or your partner snores?
If you think your snoring is caused by something more serious, like sleep apnea, you’ll want to talk to your doctor, who may recommend CPAP therapy and lifestyle changes.
However, if your snoring is more occasional, is not extremely loud, and is not punctuated by pauses in breathing during the night, you might be a good candidate for one of these anti-snoring mouthguards.

The Zquiet Anti-Snoring mouthpiece comes in two different sizes, both included in the box. Unlike others on this list, these mouthguards are ready to use right out of the box. That means, no boiling and no biting necessary.
For some, this can be a benefit, as the boil and bite fitting process can be intimidating. For others, this might be a drawback since this mouthpiece will be less custom-fit to your mouth.
That said, it is priced to reflect its more simplistic design, and considering you get two mouthpieces in your order, this is one of the most affordable products on our list.
What We Liked
- Easy to use – Without the hassle of fitting this device to your teeth, setting it up to wear is much simpler.

- May cause tooth soreness – Since it doesn’t fit to your unique teeth, it may cause tooth or jaw soreness. If you notice this device shifting the alignment of your teeth, you should stop using it.
- No refunds or returns – This product isn’t eligible for returns or refunds through Amazon.
What Is an Anti-Snoring Mouthguard?
An anti-snoring mouthguard5 is a device worn throughout the night to help prevent snoring and sometimes, moderate sleep apnea. There are three main types of anti-snoring oral devices5:
- Mandibular advancement devices – These are made from molded hard plastic and they snap over the lower jaw and upper teeth. They work by repositioning the jaw forward by a large degree.
- Mouth guards – These are usually made from plastic and can help move the jaw forward but to a lesser degree.
- Tongue retaining devices – Rather than reposition the jaw, a tongue retaining device will reposition the tongue. It is like a soft, plastic splint that prevents the tongue from falling backward throughout the night.5
The reason anti-snoring mouthguards like the ones on this list work is that they move the jaw into a forward position and hold it there throughout the night.5 This helps keep your airway open and prevents the tissues in the back of your throat from vibrating together, which causes that snoring sound.5
What to Look for in Anti-Snoring Mouthguard
Type of Appliance
As mentioned, there are three main kinds of anti-snoring oral appliances: mandibular advancement devices, mouthguards, and tongue-retaining devices.5 Mandibular advancement devices reposition the jaw to a greater degree and are usually custom-made by a dentist. They are available by prescription only and can cost more money.5
Mouthguards work by moving the jaw forward, but to a lesser degree. As such, they can be available over-the-counter and cost less.5
Tongue-retaining devices work by holding your tongue in a particular position, so it won’t fall backward and block your airway during sleep. Oftentimes, you’ll need a sleep apnea diagnosis and a prescription to get one of these. However, many people report that tongue-retaining devices are quite uncomfortable.5
The “most customizable” mouthguard is a mandibular advancement device because it is designed specifically for you by a dentist. However, many over-the-counter mouthguards are also customizable. When shopping, look for the words “boil and bite,” which means the mouth guard can mold to your mouth and teeth.
Some over-the-counter mouthguards (like the last one mentioned on our list) are not customizable to your unique teeth and mouth, but they may be adjustable in other ways or come in various sizes.
Most over-the-counter anti-snoring mouthguards are made from a combination of hard and soft plastics.5 By contrast, most dentist-designed mandibular advancement devices will include some combination of plastic and metal.5
When shopping for an over-the-counter device, make sure that it says the device is “BPA-free.” BPA, or bisphenol A, is a chemical used in plastics that could be harmful to human health.3 If you happen to have a latex allergy, you’ll also want to make sure that your mouthguard says “latex-free.”
When it comes to sticking to any sort of anti-snoring or sleep apnea treatment, comfort is key.
Most people report it takes a few nights to a week to get used to sleeping with their new anti-snoring mouthguard, but while some initial discomfort is to be expected, it should never feel painful, nor should it move or loosen your teeth.
If it feels painful, it may be a sign that it is moving your jaw too far forward and you need to adjust it to a lesser degree. If this doesn’t help, discontinue using the device or consult your dentist or healthcare provider.
Many anti-snoring mouthguards are adjustable. This means they are able to move your jaw forward to a greater or lesser degree; usually, this is somewhere between 1 and 6 millimeters.
Adjustability can be a helpful feature for getting used to your device. In this way, you can start on the lowest setting and then increase it as necessary.
Cleaning and Care
Any anti-snoring device will be subject to a great deal of wear and tear inside of your mouth, especially if you’re a teeth grinder. This means you’ll likely have to replace your mouthguard at least every nine months6 (if not sooner). To extend the lifespan of your device and keep your mouth healthy, experts recommend the following tips6:
- Clean it with baking soda and water once a week
- Brush it with toothpaste and a toothbrush daily
- Let it soak with denture tablets once a week
- Store your device in a cool, dry place every day
It’s also important to make sure your mouth is clean each night before you put in your anti-snoring mouthpiece to prevent any bacteria buildup.
Over-the-Counter or Prescription
The general rule is that the more advanced and customized the anti-snoring device, the more likely you will need a prescription to obtain it. For example, mandibular advancement devices, custom-created by dentists, are available by prescription only. Anti-snoring mouthguards are available both over-the-counter and by prescription.
Also, if you’re trying to use insurance to help pay for your anti-snoring device, you’ll need a prescription. That said, most over-the-counter anti-snoring mouthguards are affordable without insurance.
Trial Periods and Warranties
Many anti-snoring mouthguards offer trial periods and/or warranties. During the trial period, you’ll be able to try out the mouthguard at home. If it doesn’t work for you, you should be able to send it back during your trial period for a refund. Oftentimes, trial periods are between one and three months.
A warranty, on the other hand, generally lasts longer and should provide coverage in the event your device breaks within the warranty period. The company will usually replace or repair the device. However, it’s more likely they’ll just replace an anti-snoring mouthguard rather than repair it.
Look for the words “FDA cleared” or “FDA approved”7 when shopping for your anti-snoring mouthguard. “FDA cleared” means the device has undergone a 510(k) submission and has been cleared to be sold by the FDA, whereas “FDA approved” means the device has undergone a rigorous review and approval process by the FDA.7
Other Anti-Snoring Devices
- Nasal dilators – Nasal dilators can be either placed along the bridge of the outside of the nose (nasal strips) or internally as mechanical devices8. The purpose of a nasal dilator is to dilate (expand) the nose to allow more airflow in.8
- Nasal strips – Nasal strips are an affordable, over-the-counter type of nasal dilator.8 They are adhesive and placed on the outside of the nose and can help with mild cases of snoring. However, experts say9 that nasal strips won’t help those with sleep apnea or other underlying conditions.
- Pillows – Certain pillows can help with snoring by elevating the head to keep the airway from collapsing. Explore our picks for the best pillows for snoring here.
- Smart devices – There are all sorts of smart devices to help with snoring, including mechanical dilators and apps on your phone that listen for snoring. There’s also the Oura ring, which measures sleep quality, and even pillows that inflate or deflate, depending on how you’re breathing.
- Adjustable bases – Research shows that sleeping at an inclined position can reduce snoring10. This is because the airways can remain more open. Adjustable bed frames can be a great way to elevate your torso until you notice a decrease in your snoring.
When Should You See a Doctor About Your Snoring?
Experts at Yale Medicine advise speaking to your doctor about snoring if you snore loudly and regularly11. This is often a sign of obstructive sleep apnea12, a serious sleep disorder in which the breathing starts and stops throughout the night.
Other indications it might be sleep apnea include excess weight, changes in memory, inability to concentrate, insomnia, morning headaches, dry mouth, irritability, and daytime fatigue.12
If left untreated, sleep apnea can lead to serious health complications, including an increased risk of heart disease, high blood pressure, type 2 diabetes, metabolic syndrome, liver problems, and complications with surgeries and certain medications.12
Frequently Asked Questions
Do mouthguards actually stop snoring?
For people whose snoring is caused by a narrowing of the airway due to the jaw or tongue relaxing during sleep, certain mouthguards could help reduce snoring. For those who are snoring because of a nasal obstruction (like congestion or a deviated septum), mouthguards won’t alleviate snoring.
What are the side effects of anti-snoring mouthguards?
Some possible side effects13 of anti-snoring mouthguards include dry mouth, drooling, loose teeth, bite change, a negative impact on dental work, or pain in the teeth or jaw.
Do you have to use an anti-snoring mouthguard every night?
If you are using your anti-snoring mouthguard to treat sleep apnea, you’ll need to use it (or some other sleep apnea treatment like CPAP therapy) every night. You don’t want to leave sleep apnea untreated, even occasionally, as it can cause major health complications.12
If you don’t have sleep apnea and are simply using your mouthguard to treat mild snoring, you can use it every night, but it won’t be dangerous if you don’t.
