Teeth grinding, a medical condition called bruxism, is caused by clenched jaw muscles and can create bothersome symptoms like headaches, jaw pain, chipped teeth, and sleep apnea. While no cure has been discovered for bruxism, sleepers who struggle with the condition can find relief and protection by wearing a specialized mouthguard when they sleep.

Whether you struggle with genetic bruxism or find yourself grinding your teeth at night more frequently due to stress and anxiety, a nightguard will alleviate grinding and, in some cases, train you to stop grinding altogether. Nightguards can be fitted custom in the dentist’s office or purchased over the counter at drugstores. Keep reading to discover our recommendations for the best mouth guards for sleeping. We’ve also included a shopping guide with considerations for buying and an explanation of the different types of night guards available today.

Mouth Guard Buying Guide

Types of Mouth Guards for Sleep

There are three common mouthguard designs: custom impression, boil-and-bite, and stock. Below, we explore the three types and share the pros and cons of each.

  • Custom Impression—The most expensive of the three options, custom dental mouth guards are created with an impression of a sleeper’s mouth. These types of mouthguards require a visit to the dentist’s office and can cost $500 or more. Some custom designs are available for purchase online. In these cases, purchasers send their dental impression to the company and receive their customized mouth guard by mail. While costly, these mouth guards produce excellent results due to their tailored designs.
  • Boil-and-bite—Made from material that softens in hot water, the owner submerges the mouthguard in boiling water, allows it to cool, and then bites down to create a customized impression. While not as advanced as custom models, these are more affordable.
  • Stock—Typically “one size fits all,” stock mouth guards are not customizable or trimmable but are the most inexpensive option.


When choosing a mouth guard for sleep, it’s important to weigh the following factors:

  • Cost—Your budget will determine the type of mouthguard you can afford, as dental impression models can cost $500 or more. Boil-and-bite and stock mouth guards typically cost $30 or less.
  • Molded or one-size-fits-all—If you suffer from severe bruxism, a moldable night tray may be more effective.
  • Trimmable—Some models can be trimmed with scissors to achieve a better fit.
  • Cleaning instructions—Most guards require a simple rinse, but some options require time-consuming cleanings with costly solutions.
  • Impressions—If an impression is required, consider the costs and timeline of mailing the impression to the manufacturer and waiting for your trays. This can range from 30 to 365 nights.

How to Choose the Right Mouth Guard for Sleep

Sleep bruxism is difficult to treat, but it isn’t impossible to prevent bothersome symptoms with the right mouthguard. If you’re “wired” to be someone who grinds their teeth or if you suffer from jaw pain as a result of exacerbating factors like stress, alcohol, and caffeine, use the list of our best mouth guards for sleep above to get you started in your search. These options can provide relief if you’re not interested in visiting the dentist just yet for a full consultation just yet.
