Snoring is a common occurrence that can have significant negative effects. There are several solutions for those who want to stop snoring, including reviewing sleep hygiene, cutting back on alcohol, and trying a new mattress. Anti-snoring oral appliances, like the Snore Guard, can also be an effective solution.

In order to decide if an anti-snoring device may be right for you, it’s important to understand how they work and where to find them. We’ll take a closer look at the Snore Guard, delving into its overall performance, how it helps alleviate snoring, and where you can buy it.

Snore Guard Mouthpiece: Our Verdict

The Snore Guard is a mandibular advancement device (MAD) designed to reduce or eliminate snoring. MADs can also be used to treat symptoms of mild to moderate obstructive sleep apnea (OSA). The Snore Guard in particular works by gently pulling the lower jaw forward to increase airflow through the upper airway and back of the throat.

The Snore Guard consists of two connected plastic trays. The upper component of the Snore Guard is fitted to the roof of the mouth, while the lower component creates a ramp around the lower teeth. A central opening allows for mouth breathing.

You can customize the device by following a relatively simple boil-and-bite setup outlined in the accompanying information guide. This process is similar to fitting an athletic mouthguard.

With careful fitting and regular use, the Snore Guard can be a good option for those who snore or have OSA.

Pros and Cons

Although the appliance is available over the counter in Canada, those who live in the U.S. need to visit a doctor or dentist for a Snore Guard referral. While some side effects may affect sleepers for the first week or two, these usually fade with regular use.

  • Used in the U.S. since 1989
  • Available over the counter in Canada
  • Slimmer and lighter design than other mouth guards
  • Available in the U.S. by prescription only
  • Sleepers may experience initial tooth, jaw, or gum pain
  • Not adjustable

Who Should Use the Snore Guard Mouthpiece?

Individuals who snore and those with mild to moderate obstructive sleep apnea may benefit from the Snore Guard. However, the device is not suitable for everybody. Be sure to check with a doctor or dentist to see if the Snore Guard is a good option for you.

Who Is It Ideal For?
Who Should Avoid It?
  • Sleepers hoping to reduce or eliminate snoring or symptoms of obstructive sleep apnea
  • Adults with overall good physical and oral health
  • Those with severe obstructive or central sleep apnea
  • Sleepers with respiratory disorders, including emphysema and chronic asthma
  • People with diseases of the gums or mouth as well as those with loose teeth, dentures, orthodontia, or new dental implants

How Does the Snore Guard Mouthpiece Work?

During sleep, the soft tissues and muscles at the back of the throat can partially block the airway. These obstructions vibrate with each breath, causing a snoring sound. The Snore Guard works by gently propping the lower jaw forward during sleep. Repositioning the jaw like this can help to open the airway and reduce or eliminate the vibrations that cause snoring.


Approved by the Food and Drug Administration (FDA) in 1989, the Snore Guard can help those who snore and those who experience mild to moderate obstructive sleep apnea. Individuals with central sleep apnea or severe cases of OSA should consider other options.

Price and Size Options

The Snore Guard is a one-size-fits all customizable mouthpiece. It’s available over the counter in Canada, with prices ranging between $45 and $50 Canadian dollars. Prices vary for those who reside in the U.S., as sleepers need to visit a doctor or dentist to obtain a Snore Guard.


The device has a boil-and-bite design that allows sleepers to customize the fit to their mouths. No further adjustments can be made after the initial fitting.


Made of two polycarbonate thermoplastics that have been fused together, the Snore Guard has a durable outer shell and a softer inner lining that holds the dental impression and grips your teeth for a secure fit.


The average lifespan of a Snore Guard is three to six months, but wear and tear varies. Sleepers who tend to clench or grind their teeth may find they need to replace their Snore Guard more frequently.

Cleaning and Maintenance

The Snore Guard Mouthpiece should only be worn after you’ve cleaned your teeth. After wearing, rinse it with warm water, dry it, and store it in the provided case. You can brush the Snore Guard with a toothbrush and toothpaste as needed to keep it clean.

Where Can You Get the Snore Guard Mouthpiece?

The Snore Guard is available without a prescription in Canada via Amazon and third-party retailers like Walmart and SDM. While the Snore Guard has been FDA approved for many years, those who reside in the U.S. must visit a doctor or dentist to get one.
