Best Mouthguards for Teeth Grinding in 2026

Waking up with a sore jaw or headache can be a sign that you’re grinding your teeth at night — a condition known as bruxism. Currently, there is no cure for bruxism. Left untreated, teeth grinding can cause extensive damage to your teeth, interfere with your sleep, and frustrate your bed partner. Thankfully, using a mouthguard specifically designed for teeth grinding can protect your teeth and help you get the rest you need.

In this guide, we’ll introduce our team’s picks for the best mouthguards for teeth grinding. We go over what features to consider when looking for a mouthguard, share some of the best brands on the market, and address common questions to help you make an informed decision. 

Keep in mind that mouthguards can offer significant relief for many, but they don’t work for everyone. We recommend consulting your dentist or healthcare provider to understand the underlying causes of your teeth grinding and discuss the most effective treatment options.

Smile Brilliant Night Guard

15% off Shop At Smile Brilliant

Price: $149

The Smile Brilliant Night Guard balances softness and durability. It is crafted with a custom fit for additional comfort. Each mouthguard measures 2mm thick. The material should hold up to heavy grinding for around 3 months of nightly use.

Three package options are available, containing one, two, or four custom-fitted night guards with travel cases. The company recommends you select a package based on your level of grinding, with heavier teeth grinders needing additional mouthguards so that they can replace the one they use more often.

When a customer places their order, they will first receive a free impression kit to take a mold of their teeth at home. The molding process takes around 15 minutes. Then, the customer ships the impression to a lab in a prepaid envelope, and the lab produces a custom mouthguard.

Smile Brilliant saves each impression in a digitalized format, so reordering is a quick and straightforward process. Replacement mouthguards are available at a lower price than the initial purchase. Customers may use funds from HSA or FSA accounts for first-time payments and reorders.

The Smile Brilliant Night Guard comes with a 45-day trial. Customers receive a full refund of the purchase price minus shipping fees if they’re not satisfied. If you want to shop in bulk, you can purchase four mouthguards priced at $49 apiece during non-sales periods. Standard purchases qualify for a 13% discount. Smile Brilliant also partners with insurance companies, resulting in discounts of up to 25% for custom-fitted mouthguard packages.

Trial Period:

Most anti-bruxism mouthguards measure between 1mm and 2mm thick, making them suitable for people with light to moderate teeth grinding. Those with more severe symptoms may need a stronger device such as the Extra Durable Guard from JS Dental Labs. Measuring 3mm thick and formed from an FDA-cleared thermoplastic polyester, the guard essentially acts as a shock absorber whenever you grind or clench. While the guard is robust, the material is fairly flexible and shouldn’t feel too rigid.

You can choose from upper or lower trays. Customization is simple and straightforward. After receiving your kit in the mail, you’ll make an impression at home — this process can be completed in a matter of minutes — and send it back to JS Dental Labs. Most people receive their finished mouthguard within 5 business days. The guard is available in clear and turquoise designs. You can wear the guard with dentures or dental implants,

The Extra Durable Guard comes with a 365-night trial period, which is quite generous compared to trials offered by competing brands. Standard shipping costs $1, but JS Dental Labs deducts this charge from your purchase after the trial ends.

The Chomper Labs Night Guard is custom made to fit the user’s teeth, and four unique selections are available. This allows for greater personalization to better fit the individual’s needs.

The Soft model measures 3mm thick and uses a flexible, rubber-like material. It is designed for moderate clenching or light grinding. Measuring 2.5mm thick, the Hybrid is soft on the inside and hard on the outside to protect against moderate to heavy grinding. The 2mm thick Hard option consists of rigid copolyester material to hold up to heavy to severe grinding. The Retainer also uses a hard material. It measures 1mm to 1.5mm thick and is intended to protect against grinding while preventing the teeth from shifting.

As a full-service dental lab, customers can contact Chomper Labs for additional customization options. Chomper Labs can adjust the thickness or use special materials to accommodate customers.

After a shopper places their order, they’ll receive an impression kit to take a mold of their teeth at home. They then use the included prepaid envelope to send the mold to the lab, which will custom-make the mouthguard and finish it by hand for a more precise fit.

If the customer decides their Chomper Labs mouthguard isn’t right for them during the first 100 days, Chomper Labs will make adjustments or issue a replacement at no charge. If the customer isn’t satisfied after the adjustment or replacement, they can return the product for a full refund within this trial period, minus shipping costs.

Each custom mouthguard also comes with a 6-month warranty. Chomper Labs maintains impressions for two years to simplify reordering.

The Remi Custom Night Guard allows customers to choose between a one-time purchase or a Remi Club membership. With the free membership, you’ll receive a new Night Guard every 6 months for a discounted price. You can pause, ski, or cancel the membership at any time. Those frequently purchasing new mouthpieces may prefer this subscribe-and-save option.

Every Remi order includes two Night Guards – your choice of two upper devices, two lower, or one of each. This lets you decide what works best for you and still have a backup device if needed. You can request just one or the other on subsequent purchases. The mouthguard is made from hard-soft plastic that is dental-grade and free from Bisphenol A (BPA). Mouthguards are also compatible with the brand’s teeth whitening gel.

After purchasing the Custom Night Guard, Remi ships you two impression kits just in case your first impression doesn’t come out right. A Remi “Impression Specialist” reviews photos of your impression to determine whether you’re all set, or if another mold is needed. If you need extra support, you can book a Zoom appointment with a dentist on Remi’s team for a walkthrough of the process.

Depending on how hard you grind your teeth, you can choose between three thicknesses – 1 millimeters (mm), 1.3 mm, or 2 mm. The kit comes with an information card to help you make your decision. The company stores your impression and preferences to ensure you get the same fit with every purchase.

Remi offers a 45-day guarantee and return period, during which you can test the fit of the mouthguard, request a new impression kit for free, and reach out to Remi’s customer support team if you have questions. Shipping is free to all 50 states, and expedited delivery options are available.

Revived Smiles Custom Nightguard

Price: $130

Many people deal with painful, debilitating bruxism that causes pain and discomfort throughout the 24-hour cycle. For others, grinding is less intense but still disruptive to sleep. Sleepers in the latter group are prime candidates for the Revived Smiles Custom Nightguard, a 3mm device designed to prevent grinding in your upper and lower teeth. Three strengths are available to alleviate bruxism for each wearer, regardless of how much they grind their teeth.

The soft design is ideal for people who experience light to moderate grinding, while the hard model can address severe bruxism symptoms. Many people will find the hard/soft hybrid design optimal, as it features a supple interior that feels gentle on the teeth and gums and a tough outer shell for added durability. You can also order trays for the upper or lower teeth, depending on where your most intense grinding takes place.

After placing your order, Revived Smiles will mail you a kit for creating a personalized impression of your teeth at home using the boil-and-bite method. Once you’re satisfied with the mold — it may take more than one attempt — you’ll send the kit back to Revived Smiles. Your custom-fitted nightguard should arrive within 2 to 3 weeks.

Revived Smiles offers a 60-day “Smile Guarantee,” allowing you to return the mouthguard for a full refund if you aren’t satisfied after wearing it for 60 nights. Customers who sign up for an ongoing subscription with the company qualify for major perks, including a 40% discount on all replacement mouthguards and bonus discounts for their first and second purchases.

While a mouthguard for teeth grinding is an important purchase you shouldn’t necessarily skimp on, you can save some money if you don’t want or need a custom-fitted device. The SmartGuard RX Dental Guard is a boil-and-bite mouthpiece made from flexible thermoplastic. You’ll use hot water to soften the material, and cold water to preserve the impression — a detailed instructional video can be found on SmartGuard RX’s website. This process allows you to instantly customize the guard at home, rather than waiting for a lab to prepare and mail it to you.

Unlike other anti-bruxism mouthguards that mold around your upper and lower teeth, the Dental Guard only covers your top two front teeth. This limited coverage may be more comfortable for sleeping. The guard does not contain any latex or BPA, and has been cleared by the Food and Drug Administration.

The Dental Guard has been approved for adults 18 or older, but some people should not use the device. These include anyone with braces, dentures, or dental implants, as well as those with loose teeth or medical conditions like TMJ. You should speak to a dentist before using the guard if you have loose fillings or caps, gum disease, or two or more teeth missing.

Each order includes two customizable molds and a storage container. Even with two guards, the cost is significantly lower compared to custom-fitted mouthpieces. SmartGuard RX backs the Dental guard with a 3-year “no-grind-through” guarantee.

What to Look for in a Mouthguard for Teeth Grinding

Mouthguards help to prevent teeth grinding by creating a barrier between the teeth. These simple devices can protect teeth from wear and tear caused by clenching and grinding, as well as reduce tension in the jaw muscles.

We’ve created the following guide to walk you through the different types of mouthguards for teeth grinding and help you consider materials, fit, and pricing to find the best one for your teeth.

Mouthguard Types

There are several types of mouthguards to consider, each with its own benefits and potential drawbacks. While the best choice is likely a mouthguard custom-fitted by a dentist, understanding over-the-counter options can help you find the type that will work with your needs and budget.

It’s important to note that other types of mouthguards, like those for sports or snoring, are not effective at preventing teeth grinding. These are designed for different purposes and are not a substitute for seeing a dentist or finding a mouthguard made specifically for teeth grinding.

Fit and Comfort

A mouthguard needs to be well-fitted to ensure comfort and effectiveness. Custom-fit options can be made from dental impressions that can be taken at home or your dentist’s office. Custom mouthguards ensure the best fit by conforming to the unique contours of your teeth and gums.

Some brands give you the choice between mouthguards for your upper or lower teeth. The choice between an upper or lower mouthguard often comes down to personal preferences and what’s effective in eliminating nighttime teeth grinding. When in doubt, talk to your dentist for support in finding the right mouthguard or other treatment approach.

Materials and Durability

Mouthguards are typically made from different types of plastics, like vinyl or acrylic. The choice of material can affect a mouthguard’s comfort and durability. High-quality materials can better withstand nightly grinding without wearing out quickly. Opting for a durable mouthguard not only offers better protection but also proves more cost-effective in the long run.

Many people who grind and clench their teeth find that dual-layer mouthguards, which combine a tough outer layer with a softer inner layer, are comfortable without sacrificing durability. Discussing options with your dentist is the best way to determine the most effective choice for you.

Pricing and Where to Buy

The cost of over-the-counter mouthguards varies widely, typically ranging from $20 for simple over-the-counter options to $200 or more for custom-fit models. Factors influencing the price include the type of mouthguard, the brand, whether it’s custom-made, and policies the company holds, like free shipping or free adjustments. You can purchase mouthguards at retail stores, online, or get them custom fitted from your dentist.

Ease of Cleaning

Whether you choose a one-size-fits-all mouthguard or a custom-fitted design, most are comparable in terms of how easily they are to clean. Clean your mouthguard based on the manufacturer’s instructions. Most often, this entails rinsing it under warm water and brushing it with a toothbrush. Allow it to air-dry completely before storing it in a ventilated container to prevent bacterial growth. Some brands ask that you store your mouthguard in a glass of water.

What Causes Teeth Grinding at Night?

Teeth grinding, or bruxism, is when a person clenches their jaw and grinds their teeth against one another. Teeth grinding can occur among adults or children. While it’s more common to grind your teeth during the day, nighttime teeth grinding can be especially problematic because it’s more challenging to stop.

Although dentists can’t always pinpoint the exact cause, grinding can be triggered by stress, medications, smoking, caffeine, and even a person’s genetics. Researchers have found that teeth grinding is more common in people with certain sleep problems, including obstructive sleep apnea and parasomnias like sleep talking and sleepwalking.

Teeth grinding can damage the teeth and increase sensitivity to hot, cold, and sugary foods. Without treatment, grinding can also lead to problems with the jaw. Other symptoms of teeth grinding include:

• Anxiety or depression
• Ear pain
• Headaches
• Eating problems

Symptoms of teeth grinding can make it harder to sleep and the noise from grinding can affect bed partners.

While this guide provides information to help you understand teeth grinding and find the best  mouthguards, we’re not offering medical advice or treatment. If you suspect that you may be grinding your teeth at night, it’s important to discuss these concerns with a doctor or dentist.
