Teeth clenching and grinding at night, also known as sleep bruxism, is a common affliction affecting about 10% of the population. Bruxism can have a number of annoying side effects; dental issues, headaches, sleeplessness and more. While it’s always good to consult a doctor or a dentist to truly diagnose your issues with bruxism, there are a number of mouthguards that can help protect your teeth while you sleep.
Here are some of our favorite mouthguards to help with grinding and clenching at night. In this guide, we’ll cover everything from sizing and thickness to the best custom guards professionally made to fit your mouth. These mouthguards cover a wide range of budgetary options as well, so you’re sure to find a guard perfect for your needs.

- These custom guards are a bigger investment than standard mouthguards, so if something goes wrong in the fitting process starting over can be more of a hassle.
While the majority of the mouthguard for teeth grinding market is low-cost, at-home moldable options, there are some companies offering professional-grade guards that requires a two-step process. First, you receive a mold kit, then you send it to the company who creates a professional-grade custom mouthguard for you. enCore’s mouthguards are our favorites in the professional category for their quality and options.
How We Chose the Best Mouthguards for Grinding
Mouthguards for grinding and clenching can be a great low-cost alternative to expensive dental options (though it’s always best to speak to a professional to make sure you’re choosing the right solution). They can be easily molded right in the comfort of your home, and because of how economical they are, should they not work the way you hope, they can be easily replaced. When we assembled our list, here are some factors we considered in deciding our favorite mouthguards.
Size and Thickness
Because these guards sit in your mouth overnight, it’s important that they stay in place and remain as unnoticeable as possible. Not only that, but they need to provide adequate thickness and support to prevent you from grinding your teeth. Our favorite mouthguards struck a balance of thickness and comfortability.
Safety and Hygienics
Again, these guards go in your mouth, so it’s a pretty big deal that they can be kept clean and won’t make you sick. We chose guards that were BPA and phthalate free, and came with retainer cases so they can be stored without risk of getting dirty when not in use.
Multiple Options in One Pack
For many people, having a pack of multiple guards of the same size is ideal; you’re essentially just getting backups for the mouthguard you plan to use. If you’re getting mouthguards for your family, or your partner, having a multi-pack with different options is a great choice; so we took those needs into consideration when assembling our list.
Tips for Picking Mouthguards for Grinding
Everyone has a different tolerance when it comes to night guards. Some people can’t sleep with any amount of restriction in their mouths, while others can go the whole night without noticing a large piece of plastic in their mouths. The important thing is finding a guard that works best for you and your tolerance, as well as the severity of your grinding.
- Mouthguard Thickness: The standard thickness for night guards is around three millimeters; this size is generally geared towards those dealing with an intermediate amount of teeth grinding or clenching. If your problem is more severe, consider a thicker model mouthguard (which can run approximately six millimeters), or thinner if your problem is less severe or you have a low tolerance for night guards (you can find some as thin as one millimeter).
- Mouthguard Size: The most common complaint about mouthguards is there’s too much excess material and it makes them uncomfortable or unwearable. If you’re worried that a standard-sized guard might be too big, consider a multi-sized pack that contains larger and smaller options so you can choose what works best for you.
Recapping the Best Mouthguards for Grinding
Grinding and clenching are common problems that affect a huge number of people. And while dentists and doctors are an important first step to getting to the root cause of an issue, mouthguards can be a great low-cost option to preventing potential damage to your teeth and help you make it through the night comfortably.
Do mouthguards help with teeth grinding?
The short answer is yes, mouthguards provide a cushioned barrier between your teeth which stops grinding and clenching. The quality of mouthguard, however, can have other effects. For example, more inexpensive, sports-style mouthguards can help with bruxism, but might have adverse effects on teeth alignment, whereas more expensive, custom guards can actually help with straightening.
What is the best mouthguard for teeth grinding?
With the plethora of mouthguard options on the market, it’s hard to say with certainty what the “best” is, because everyone will have different needs. In reality, there are two categories of mouthguards for grinding, cheaper sports mouthguards and more expensive custom guards. If you are willing to spend more, custom mouthguards can provide help with bruxism while also promoting proper teeth alignment. On the custom level, we like the guards from enCore. On the sports level, we’ve found the ConfiDental moldable guards to be a great lower cost option.
How much is a mouth guard for grinding teeth?
If purchased through a dentist, a bruxism night guard can cost upwards of $500. Sports mouthguards can be as little as $10 for a pack of four guards, and over-the-counter custom dental guards can cost between $100 and $200.
