About Snoring

What causes snoring?

Snoring happens when your body forces air through your throat when it is fully or partially blocked by the muscles and tissues of your tongue, neck, and throat. The air causes those tissues to vibrate, and the resulting sound is a snore. Snoring often results when your jaw relaxes while you sleep and causes the muscles in your throat to collapse and close off your airway.

What should I look for in an anti-snoring mouthpiece?

Many medical professionals agree that an anti-snoring oral appliance is effective if it is adjustable and, more importantly, if the user can easily adjust it on their own. An effective mouthpiece should let you advance your jaw as needed by at least 1 millimeter increments.

Customization is another key feature to look for. The more you can customize the fit of your appliance, the better it will work for you.

The proprietary design of SnoreRx allows you to adjust the advancement settings as needed without any screws, springs, or other hardware components that could damage your teeth or put a strain on your TMJ.

SnoreRx Information

How does SnoreRx work?

SnoreRx is a mandibular advancement device (MAD) that gently props your lower jaw forward. This helps maintain a clear airway while you sleep and prevents the irritating sound we call “snoring.”

SnoreRx is a one-of-a-kind snoring mouthpiece because it offers many levels of customization including the ability to advance your jaw in one-millimeter increments. Each model lets you select the advancement setting that feels and works the best for you.

Is SnoreRx safe to use?

Yes, SnoreRx is perfectly safe. The American Academy of Dental Sleep Medicine acknowledges that an oral appliance is a safe and effective treatment for the prevention of snoring. SnoreRx contains no harmful hardware like screws or springs that could pose a choking hazard or damage your teeth.

Is SnoreRx approved by the FDA?

Yes, SnoreRx has been cleared by the FDA for the reduction of snoring. In fact, SnoreRx was the very first anti-snoring mouth guard that was approved for over-the-counter use based on its history of safety and efficacy.

Is there a risk of choking while wearing SnoreRx?

No, there are no small parts on SnoreRx that could present a potential choking hazard. Every element of the device is too large to become lodged in the throat.

Do you offer a guarantee?

Yes, we offer a 30-night guarantee on our products to new customers because we are confident that SnoreRx really works. If there's any reason that you are not satisfied with your purchase, we are happy to refund you the purchase price. Please see our guarantee page for more details on our return policy.

Preparing and Adjusting SnoreRx

How do I custom fit my SnoreRx?

SnoreRx uses the boil-and-bite process to create a custom impression of your teeth. For detailed information on how to create an impression on your SnoreRx, please see our fitting instructions.

Can I retake my SnoreRx impression if it didn't come out right the first time?

Yes. If the first impression you took doesn't clearly display well-defined teeth marks, you can repeat the custom fitting steps one more time. The entire impression process can be done a total of two times.

Is SnoreRx adjustable?

Yes. SnoreRx's patented design lets you move the position of your jaw in one-millimeter increments up to six millimeters.

We recommend you start using SnoreRx on the one-millimeter setting on the first night you wear it. If the snoring hasn't reduced after 3 to 5 nights, then advance your setting by one millimeter. Wear each new SnoreRx setting for a minimum of 3 to 5 nights before you advance it again. Most users get good results on a setting of three to five millimeters.

How do I adjust SnoreRx?

SnoreRx can be adjusted in one millimeter increments to provide optimal comfort and effectiveness. For detailed information on how to adjust your SnoreRx, please refer to the adjustment instructions on the How It Works page.

Which SnoreRx setting is the best?

Most SnoreRx users find that somewhere between the three- and five-millimeter settings is enough to stop snoring. However, we recommend that you begin wearing SnoreRx at the one-millimeter setting and advance your device gradually if the snoring hasn't improved after a few nights. Every time you advance your SnoreRx, do so by just one millimeter and wear it at that setting for at least 3 to 5 nights before you move it again.

Use and Care of SnoreRx

Can SnoreRx be made larger or smaller?

SnoreRx comes in one standard size, but it accommodates most jaw sizes.

Is SnoreRx difficult to get used to wearing?

Wearing SnoreRx can become second nature for you, but as with any other oral appliance or prosthetic, it may take a little time to get used to it. Allow yourself up to five nights of consistent use to see if your mouth gets used to the feel of SnoreRx. It's perfectly normal to experience some soreness in your jaw, teeth, and gums during this adjustment phase. But if you have severe pain or discomfort that doesn't fade after a few days of use, then stop using SnoreRx immediately and contact your dentist or physician.

How do I know if SnoreRx is working?

The easiest way to tell if SnoreRx works for you is to have someone listen for snoring sounds while you sleep. If you share a bedroom with someone, then they will definitely let you know!

But when in doubt, try using a smartphone app like Sleep Score or SnoreLab to check for snoring sounds while you sleep.

Does SnoreRx allow for mouth breathing?

Although SnoreRx doesn't require you to breathe through your mouth, SnoreRx does allow for full mouth breathing due to its V-Flow™ design.

How should I care for and clean my SnoreRx?

Clean SnoreRx daily to prevent the buildup of debris and offensive odors. Aseptic Guard is a good cleaning solution that works well for many SnoreRx users. Toothbrush and toothpaste are also effective. Stay away from abrasive cleaners such as mouthwash, dishwashing soap, ammonia, bleach, and other household cleaning products. Give your SnoreRx a chance to air-dry after wearing it or cleaning it.

How long does SnoreRx last?

SnoreRx typically lasts around 6 to 11 months of use, but we can't guarantee a specific length of time as this varies from person-to-person. For example, people who have a habit of grinding their teeth or clenching their jaw while they sleep may wear out their SnoreRx device quickly and need to replace it much sooner than 6 months.

Should I tell my dentist that I am using SnoreRx?

Yes. In fact, we recommend that you tell your dentist that you are using SnoreRx at your next visit.

What should I expect when using SnoreRx?

SnoreRx can start working for you within a week, just as soon as you find the right setting. It's also important to know that dry mouth, a little initial soreness, or even excess drooling are all totally normal when you first start wearing SnoreRx. You can reduce these effects by wearing SnoreRx for a few days during waking hours for at least 45 minutes at a time to help your mouth get used to the sensation.

Does SnoreRx help with tooth grinding (bruxism)?

SnoreRx has only been approved by the FDA for the reduction of snoring, and it is not intended to address any medical condition such as tooth grinding or jaw clenching. If you grind or clench your teeth and purchase SnoreRx, you may notice that your device will need replacement within just a few months.

Should I be able to close my mouth while I'm wearing SnoreRx?

This totally depends on your individual anatomy and preference. Some people can comfortably close their lips over the device while wearing it, but others might not be able to. SnoreRx is designed to be comfortable and effective either way.

Yes! Many of our customers who have an overbite successfully use SnoreRx. We recommend that when you receive SnoreRx, make sure the device is set to the neutral setting of 1 millimeter before you take your impression and begin wearing your device.
