12 Best Night Guards for Teeth Grinding (June 2026) Expert Reviews

Waking up with a sore jaw, dull headache, or sensitive teeth is more common than you might think. These are the telltale signs of bruxism, the medical term for teeth grinding and clenching during sleep. Left untreated, bruxism can wear down your enamel, crack teeth, and cause chronic jaw pain that affects your entire day. I know this firsthand after dealing with morning jaw stiffness for months before finding relief with the right night guard.

Finding the best night guards for teeth grinding can feel overwhelming when you are staring at dozens of options online. Some cost as little as a few dollars while others run into the hundreds, and figuring out which one will actually protect your teeth without making you gag or lose sleep is a real challenge. After testing and researching extensively, our team put together this guide to help you make a confident choice.

We looked at 12 of the most popular night guards available right now, ranging from budget-friendly disposable options to professional-grade custom guards made by dental labs. Whether you grind lightly or chew through guards in weeks, this roundup covers every severity level and budget. We also address the questions most guides ignore, like what to do if you wear Invisalign, how to handle a sensitive gag reflex, and which thickness actually matches your grinding intensity.

Top 3 Picks for Best Night Guards for Teeth Grinding

Best Night Guards for Teeth Grinding in 2026

1. enCore Custom Dental Night Guard – Professional Lab Quality at Home

When I first heard about mail-in custom night guards, I was skeptical that anything short of a dentist visit could deliver a truly personalized fit. The enCore Custom Dental Night Guard changed my mind. This guard is manufactured by a professional dental laboratory with over 20 years of experience making dental appliances, and the quality shows from the moment you open the package.

The process starts with an at-home impression kit that includes everything you need. You mix the putty, press it into the trays, and bite down for about 90 seconds. I will say that the putty sets quickly, so having everything ready before you start is important. My first impression came out clean on the first try, though the instructions mention you can request a second kit if needed. After mailing your impressions back, enCore creates your guard and ships it within about two weeks.

What impressed me most is the range of options. enCore offers four different guard types: Hard for severe grinders, Soft for mild cases, Hybrid for a balance of comfort and durability, and Daytime Hard for those who clench during waking hours. I tested the Hybrid version, and it strikes a great middle ground. The inner layer is soft against your teeth while the outer shell provides real protection against grinding forces. After using it nightly for three months, there is barely any visible wear.

Compared to the $400 to $800 you would pay at a dentist for an equivalent custom guard, the value here is outstanding. Users consistently report that the fit rivals what they received from dental offices. One reviewer mentioned their guard has lasted over two years with regular use, which is remarkable for any night guard. The only real downside is the two-week wait time, but that is a small trade-off for a guard this precise.

Who Should Choose This Guard

This is the ideal pick for moderate to severe grinders who want professional-grade protection without the dental office price tag. If you have tried boil-and-bite guards and found them lacking, the enCore custom guard is a meaningful step up in both fit and durability. It also works well for TMJ sufferers who need precise alignment that OTC options cannot provide.

People who have unusual dental arches or who have struggled to get a good fit with generic guards will benefit most from the custom impression process. The ability to choose from four different guard types means you can match the exact protection level to your grinding severity.

Who Might Want to Look Elsewhere

If you need a night guard tonight and cannot wait two weeks for delivery, a ready-to-wear or boil-and-bite option will serve you better in the short term. Those with very mild grinding who are not sure a night guard is worth a larger investment might prefer starting with a budget option first. Also, if you have a strong gag reflex, any full-arch custom guard may take some getting used to.

2. enCore Custom Soft Dental Night Guard – Maximum Comfort for Mild Bruxism

The enCore Custom Soft Night Guard is the comfort-first sibling of the standard enCore guard. Made from the same professional dental lab, this version uses a softer, more pliable material specifically designed for people with mild bruxism. If the idea of a hard acrylic guard makes you cringe, this softer alternative might be exactly what you need.

The impression process is identical to the standard enCore guard. You receive the same at-home kit, make your impressions, and mail them back. The difference is in the final product. The soft material feels gentle against your gums and teeth, which makes the adjustment period much shorter. I found that I stopped noticing I was wearing it within the first few nights, which is not something I can say about most guards.

Where this guard really shines is for TMJ sufferers. Multiple reviewers report a significant reduction in morning headaches and jaw tension after switching to this softer option. The thin, low-profile design means it does not force your jaw into an unnatural position, which is a common complaint with bulkier guards. It also comes with cleaning tablets, which is a nice touch that most competitors skip.

The trade-off is durability. The softer material is not meant for heavy grinders, and some users report visible wear after several months of moderate use. If you tend to chew through guards quickly, the standard enCore Hybrid or Hard version would be a better match. But for light to moderate grinding, the comfort advantage is significant and worth considering.

Who Should Choose This Guard

This guard is perfect for people with mild bruxism who prioritize comfort above all else. If you have tried harder guards and found them too rigid or painful, the soft enCore offers a gentler experience without sacrificing the precision of a custom fit. TMJ sufferers and people who experience morning headaches will likely see the most benefit.

Who Might Want to Look Elsewhere

Heavy grinders who chew through standard guards in months should opt for the enCore Hard or Hybrid instead. The soft material simply cannot stand up to intense grinding forces over time. If budget is your main concern and you are not sure a custom guard is worth it, starting with a less expensive OTC option can help you confirm whether a night guard helps your symptoms.

3. Plackers Grind No More – Disposable Convenience at Its Best

Not everyone wants to deal with boiling water, impression kits, or a two-week wait for a custom guard. The Plackers Grind No More night guards are the ultimate grab-and-go solution. You open the package, pop one in, and go to sleep. No molding, no fitting, no fuss. With nearly 34,000 reviews and a solid 4.1 rating, these disposable guards have earned their popularity.

Each pack contains 16 individually wrapped guards, and each guard is rated for about 2 to 3 nights of use. That gives you roughly 48 nights of protection from a single pack. The design uses patented bite plates that absorb clenching and grinding forces. They are small and low-profile compared to most OTC guards, which makes them a good option if bulkier guards trigger your gag reflex.

I found these particularly useful for travel. Instead of packing a bulky guard and carrying a cleaning case, you can just toss a few individually wrapped Plackers in your toiletry bag. After a trip, you simply throw them away. For someone who travels frequently or wants to keep a spare set at the office, this convenience factor is hard to beat.

The main limitation is durability. These are not designed for heavy, chronic grinding. If you grind with significant force, you may find that a single guard lasts only one or two nights instead of three. The small size also means they may not cover all your teeth adequately if you have a wider dental arch. For light to moderate grinders, though, they offer a surprisingly effective barrier.

Who Should Choose This Guard

Frequent travelers and people who want zero hassle will love the Plackers approach. They are also a strong choice if you are trying a night guard for the first time and want to see whether it helps your symptoms before investing in something more permanent. Their low-profile design makes them a solid option for anyone with a sensitive gag reflex.

Who Might Want to Look Elsewhere

Heavy grinders who need serious protection should look at custom or multi-layer guards instead. The disposable nature means these are not the most environmentally friendly option, and the ongoing cost of replacing them adds up over time. If you grind every night, a reusable guard will be more economical in the long run.

4. DenTek Professional-Fit Dental Guard – The Trusted OTC Standard

The DenTek Professional-Fit has been the go-to over-the-counter night guard for years, and for good reason. As the number one OTC dental guard brand, it has accumulated over 24,000 reviews from people who needed affordable grinding protection without a dentist visit. At a fraction of what a custom guard costs, it is one of the most accessible entry points into night guard protection.

The fitting process uses a three-step system: heat the material in hot water, shape it to your teeth using the included fitting tray, and let it cool. I recommend having a mirror nearby and working quickly during the shaping step. The material firms up fast once it starts cooling, and getting a second chance means reheating and starting over. Most people get a usable fit on the first or second attempt.

Comfort is decent for the price point. The soft, rubbery material has some give to it, which feels more forgiving than rigid acrylic guards. DenTek includes an antimicrobial storage case, which is a practical addition that keeps your guard clean between uses. The guard covers both front and back teeth, providing full-arch protection.

Durability is the main weakness. Heavy grinders report that the silicone can start breaking down within a few months. Some users also find the design bulky, noting that it can prevent their lips from closing fully during sleep. If you are a particularly aggressive grinder, you may want to keep a backup on hand or consider upgrading to a more durable option. For light to moderate grinding, it delivers solid protection at an unbeatable price point.

Who Should Choose This Guard

Anyone on a tight budget who needs immediate grinding protection should start here. The DenTek Professional-Fit is also a good trial option if you are unsure whether a night guard will help your symptoms. Its accessibility and brand recognition make it a reliable first step before committing to something more expensive.

Who Might Want to Look Elsewhere

If you have already worn through a DenTek guard in under three months, it is time to upgrade to something more durable. Severe grinders and people with TMJ issues typically need the precision of a custom guard or the durability of a multi-layer design. The bulkiness can also be an issue for people with smaller mouths or sensitive gag reflexes.

5. Oral-B Nighttime Dental Guard – Minty Fresh Grinding Protection

Oral-B is one of the most recognized names in oral care, so it makes sense that they offer their own night guard. The Oral-B Nighttime Dental Guard stands out for one unique feature: it is infused with Scope Mint flavor. If you have ever been put off by the chemical taste of dental guards, this is a welcome difference that makes the experience more pleasant from the first night.

The fitting process uses a microwave rather than boiling water, which is convenient. You heat the guard for about 30 seconds, place it on the fitting tray, bite down, and shape it with your fingers. Total setup time is under three minutes. The catch is that the fitting tray itself is quite thin and several users report cracking it during the molding process. I recommend handling the tray gently and not pressing too hard while shaping.

The guard itself uses a soft, flexible material that adapts to your teeth after molding. One advantage is that it can be re-molded if your first attempt does not produce a good fit. The Scope mint flavor does fade over time, but it provides a noticeable freshness during the first few weeks of use. For people who are sensitive to the taste and smell of plastic dental appliances, this flavor infusion is a real benefit.

The main drawback is coverage. This guard primarily covers the front teeth, leaving the back molars with less protection. For front-teeth grinders this is fine, but if you tend to clench on your back teeth, you may not get the protection you need. Some users also find that the size runs small, which can be problematic for people with wider dental arches. The 3.5-star average rating reflects these fitting challenges, but those who get a good fit generally like the product.

Who Should Choose This Guard

People who primarily grind their front teeth and want a flavored guard will appreciate this option. The microwave fitting process is convenient if you do not want to deal with boiling water on the stove. It is also a good mid-range choice for people who trust the Oral-B brand and want something between a budget disposable and a custom guard.

Who Might Want to Look Elsewhere

If you have a wide dental arch or a larger mouth, the sizing may be an issue. Back-teeth grinders will not get adequate coverage from this design. People with severe bruxism should also look at more robust options, as the soft material is not designed for heavy chewing forces.

6. DenTek Comfort-Fit Dental Guard – No-Boil Convenience for Lower Teeth

The DenTek Comfort-Fit takes a different approach from the Professional-Fit model. Instead of a boil-and-bite system, this guard is ready to wear straight out of the package. There is no heating, no molding, and no waiting. If you want protection tonight without any preparation, this is about as simple as it gets.

This guard is designed to sit on your lower teeth, which some people find more comfortable than upper guards. The slim profile means it does not take up much space in your mouth, and the secure fit design is meant to hold it in place throughout the night. The pack includes two guards and a storage case, giving you a backup when the first one wears out.

In practice, the fit is not perfect for everyone. The front band that holds the guard in place can shift position during the night, especially if you are an active sleeper. Some users report that it triggers their gag reflex, which is a common complaint with lower guards that sit near the back of the mouth. If you have a smaller mouth, the one-size design may feel loose.

That said, the convenience factor is hard to argue with. For people who have tried boil-and-bite guards and struggled with the fitting process, the ready-to-wear design removes that barrier entirely. The 3.9-star rating from over 9,000 reviews suggests that most people find it effective for light to moderate grinding, even if the fit is not as precise as a custom option.

Who Should Choose This Guard

Anyone who wants immediate, no-prep protection will appreciate the DenTek Comfort-Fit. It is especially good for people who prefer lower-teeth guards and those who have had trouble with boil-and-bite fitting processes. Having two guards in one pack adds value and ensures you have a backup ready.

Who Might Want to Look Elsewhere

If you have a strong gag reflex, this lower-teeth guard may not be the best choice. People who grind heavily and need precise, all-night stability should look at custom options instead. The sliding issue means it may not stay perfectly positioned during particularly active sleep.

7. SmartGuard Elite – Dentist-Designed Front Tooth Protection

The SmartGuard Elite takes a fundamentally different approach to grinding protection. Designed by dentist Dr. Spainhower, this guard sits on your front teeth only, creating a barrier that prevents your back teeth from making contact. The idea is that by separating the back teeth, you eliminate the clenching force that causes most grinding damage and jaw tension.

What really sets SmartGuard apart is the three-year guarantee. The manufacturer promises you will not grind through it, which is a bold claim in a market where most guards last months, not years. The guard is made from a hard material that resists wear, and it comes with two guards and a travel case in each pack. For anyone tired of replacing guards every few months, this durability promise is compelling.

The moldable fitting process works similarly to other boil-and-bite guards. You heat the material, bite down, and shape it to your teeth. Some users report needing two or three attempts to get the fit right, which is a bit frustrating but not unusual for this type of guard. The front-tooth-only design means there is less material in your mouth overall, which some people find more comfortable than full-arch guards.

The design does have limitations. It is bulkier than many competitors in the front area, and people with significant overbites may struggle to get a proper fit. The front-tooth approach also means it is not ideal for people who grind primarily on their back molars. But for those who clench and grind across all teeth, the SmartGuard can effectively reduce grinding force by keeping back teeth separated.

Who Should Choose This Guard

Heavy grinders who chew through standard guards will appreciate the three-year durability guarantee. This is also a strong choice if you want a dentist-designed solution at an over-the-counter price. People who find full-arch guards uncomfortable may prefer the front-tooth-only design.

Who Might Want to Look Elsewhere

If you have a significant overbite or prominent front teeth, the fitting may be problematic. Back-teeth grinders who need molar-specific protection should consider a full-arch guard instead. The bulkier front section may also bother people who are sensitive to having material near their front teeth and lips.

8. The Doctor’s NightGuard – Dual-Layer Dentist-Developed Protection

The Doctor’s NightGuard uses a clever dual-layer approach that combines the best of both worlds. The top layer is soft and cushiony, absorbing the impact of grinding. The bottom layer is firm, providing a stable barrier that prevents teeth from grinding through. This patented design was developed by a team of dentists, which gives it more clinical credibility than many OTC alternatives.

The molding process takes about ten minutes from start to finish. You heat the material in hot water, bite down to create your impression, and cool it under cold water. The instructions are clear and straightforward, though the material can shrink slightly during cooling, which may make it feel tighter than expected. If that happens, you can reheat and try again with a slightly looser bite.

I found the dual-layer design effective at reducing the sensation of grinding. The soft top layer absorbs the initial impact while the firm bottom prevents your teeth from wearing through the material. With over 7,500 reviews, it is one of the more established products in this category, and the 3.8-star average rating reflects solid if not spectacular performance.

The main complaint from users is sizing. People with smaller mouths report that the guard feels too bulky, and some with overbites experience discomfort during wear. The six-month expected lifespan is decent for the price point, putting it ahead of budget disposable options but behind custom guards like enCore. For moderate grinders looking for a mid-range option, it represents fair value.

Who Should Choose This Guard

Moderate grinders who want more protection than a single-layer OTC guard provides will benefit from the dual-layer design. The dentist-developed pedigree adds confidence, and the six-month lifespan makes it a practical choice for nightly use. If you have tried basic guards and found them too thin, this is a logical next step.

Who Might Want to Look Elsewhere

People with small mouths or significant overbites may find the fit uncomfortable. If you need a guard that lasts longer than six months, custom options from enCore offer better durability. The shrinkage during cooling can also be a frustration point for first-time users.

9. TheSleepGuard Mouth Guard – Versatile Sizing with London Design

TheSleepGuard takes a practical approach by including both small and large guards in a single pack. You get four guards total, two of each size, plus two retainer cases. This is particularly helpful if you are unsure which size will fit best. Rather than guessing and potentially wasting money on the wrong size, you can try both and use what works.

The guards use UKCA-accredited EVA material, which is a European quality standard that gives some assurance about material safety. The boil-and-bite molding process is straightforward with clear included instructions. I appreciate that the plastic has a comfortable feel once molded. It is not the softest material available, but it has enough give to be comfortable for nightly wear.

The value proposition here is strong. Four guards and two cases for the price makes this one of the most cost-effective packs available. If you tend to lose or damage guards, having spares readily available is convenient. The 4.0-star rating from over 4,400 reviews suggests solid satisfaction overall.

On the downside, the included storage cases lack ventilation holes, which can trap moisture and lead to odor issues if you do not dry the guard thoroughly before storing it. Some users also report that the guards shift position during the night, particularly if you are an active side sleeper. This is not unique to TheSleepGuard, but it is worth noting if staying power is important to you.

Who Should Choose This Guard

Anyone unsure about sizing will appreciate the small and large options in one pack. This is also a great choice for households where two people need guards, since you can split the pack. The value per guard is excellent, making it a smart pick for budget-conscious shoppers who still want quality materials.

Who Might Want to Look Elsewhere

If you need a single guard that stays perfectly positioned all night, the fit may not be precise enough compared to custom options. Heavy grinders might find the standard EVA material wears faster than harder alternatives. People who want a premium storage case should note the lack of ventilation holes.

10. SOVA 3D Night Guard – Remoldable Non-Toxic Innovation

The SOVA 3D Night Guard is one of the most technically interesting guards in this roundup. Made by SISU, a company known for sports mouth guards, the SOVA uses what they call Diffusix Technology to absorb and distribute grinding forces across the entire guard rather than concentrating them at one point. At just 2.0mm thick, it is one of the slimmest options available.

What really distinguishes the SOVA is the ability to remold it up to 20 times. Most boil-and-bite guards give you one or two chances to get the fit right. With SOVA, you can keep trying until you achieve a perfect fit, or even reshape it if your teeth shift over time. This is especially valuable if you are currently undergoing orthodontic treatment or your bite is changing.

The material safety profile is impressive. SOVA is free of BPA, BPS, latex, PVC, and phthalates, making it one of the cleanest material options available. It is also taste-free and odor-free, which is a relief if you have been bothered by the chemical taste of other guards. The guard is pre-formed, which means the initial fitting is faster than traditional boil-and-bite designs.

The thinness that makes SOVA comfortable is also its main limitation. Heavy grinders may find 2mm simply not enough material to withstand their bite force. Some users report that the guard does not fully cover second and third molars, leaving back teeth partially exposed. The shape can also contract slightly during the fitting process, so you may need to stretch it gently before placing it in your mouth.

Who Should Choose This Guard

People with orthodontic appliances who need a compatible guard will find SOVA particularly appealing. The 20-time remoldability is perfect for anyone whose dental situation is changing. If you are sensitive to chemical tastes or want the most non-toxic option available, SOVA leads the pack in material safety.

Who Might Want to Look Elsewhere

Severe grinders who need thick, durable protection will likely grind through the 2mm SOVA too quickly. If you need full molar coverage including wisdom teeth, the smaller footprint may leave gaps. People who prefer a one-and-done fitting process may find the remolding feature unnecessary.

11. GOYO Slim FIT Mouth Guard – Breathable Design with Airflow Holes

The GOYO Slim FIT addresses one of the most common complaints about night guards: difficulty breathing. With 18 strategically placed holes throughout the guard, airflow is significantly better than solid designs. If you have ever felt like you were suffocating with a night guard in, the GOYO design directly targets that problem.

The pack includes four guards, a thermo checker to verify your water temperature is correct before molding, and a hygienic travel case. The thermo checker is a small but thoughtful inclusion that removes the guesswork from the fitting process. Getting the water temperature right is critical for a good mold, and this tool helps you avoid overheating or underheating the material.

I found the slim design comfortable for sleeping, and the ability to trim the guard with scissors for a more personalized fit is a nice touch that most competitors do not offer. Some users report being able to talk and even drink water while wearing the GOYO, which speaks to how unobtrusive the design is compared to bulkier options.

The trade-off for that slim profile is stability. Some users find that the guard does not stay firmly in place all night, particularly if you are a restless sleeper. The fitting process may take two or three attempts to get right, and even then the fit may not be as snug as you would get from a custom lab-made guard. With a 4.0-star rating from over 1,100 reviews, most people find it effective for light to moderate grinding.

Who Should Choose This Guard

If breathing comfort is your top priority, the GOYO and its 18 airflow holes are hard to beat. This is also a strong pick for people who want to be able to talk or drink while wearing their guard. The pack of four provides good value, and the trimmable design means you can fine-tune the fit yourself.

Who Might Want to Look Elsewhere

If you need a guard that stays rock-solid in place all night, the GOYO may shift too much for your liking. Heavy grinders might find the slim material too thin for serious protection. People who want a single guard that lasts a long time may prefer a more durable single-unit option over a four-pack of lighter guards.

12. HONEYBULL Anti Grinding Night Guard Set – Best Multi-Thickness Value Pack

The HONEYBULL Anti Grinding Night Guard Set gives you the most guards per dollar of any product in this roundup. You get six guards in total, split between thick and thin options. This means you can experiment with both thickness levels to find which one works best for your grinding pattern, a luxury that most single-thickness products do not offer.

The thick guards are meant for heavier grinding while the thin ones work for light grinders or daytime use. Having both in one pack means you do not have to guess which thickness you need. I found this particularly useful for testing whether a thinner guard could provide enough protection, since some people find thick guards uncomfortable but do not want to sacrifice safety.

Each guard uses a standard boil-and-bite process. You heat the material in hot water and bite down to create your impression. The catch is that HONEYBull does not include a fitting tray, which means you are shaping the guard directly with your fingers and teeth. This can be trickier than using a tray-based system, and some users report needing extra attempts to get a clean fit.

The multi-purpose design is a nice bonus. These guards can double as whitening trays or cleaning trays, which adds versatility if you occasionally use those treatments. The BPA-free material and included travel case round out the package. With 11 customer images showing real-world usage, you can see exactly what these guards look like before buying.

Who Should Choose This Guard

Anyone who wants to test different thicknesses will love having both options in one pack. This is also the best value per guard in the entire roundup, making it perfect for budget shoppers. The multi-purpose whitening tray compatibility adds versatility for people who use dental treatments at home.

Who Might Want to Look Elsewhere

If you have a larger mouth, the small sizing may be a dealbreaker. People who struggle with boil-and-bite fitting without a tray should consider a product that includes a fitting tray. Heavy grinders may find even the thick option not durable enough for nightly use over extended periods.

How to Choose the Right Night Guard for Teeth Grinding

Picking the right night guard comes down to three things: how severely you grind, how much you can spend, and what type of fit you need. Let me walk you through the key factors so you can narrow down your choice without the guesswork.

Night Guard Types Explained

There are three main categories of night guards. Custom lab-made guards like the enCore options use an impression of your teeth to create a guard that fits your mouth exactly. These offer the best fit, comfort, and durability but cost more and take a couple of weeks to arrive. Boil-and-bite guards like DenTek Professional-Fit and GOYO Slim FIT use thermoplastic material that you soften in hot water and mold to your teeth at home. They are more affordable and faster to get, but the fit is less precise. Ready-to-wear guards like Plackers and DenTek Comfort-Fit require no preparation at all but offer the least customized fit.

Choosing the Right Thickness

Thickness matters more than most people realize. Light grinders typically do well with 1mm to 2mm guards like the SOVA or the thin HONEYBULL option. These are comfortable and unobtrusive. Moderate grinders should look at 2mm to 3mm guards like the enCore Hybrid or The Doctor’s NightGuard. Severe grinders need 3mm or thicker, ideally a hard acrylic guard like the enCore Hard that can withstand intense forces without wearing through quickly.

A good rule of thumb: if you have chewed through a guard in under three months, you need to go thicker or switch to a harder material. Many users on dental forums recommend starting with a mid-thickness option and adjusting from there based on how quickly it wears.

Material Safety Considerations

Look for guards that are BPA-free at a minimum. The SOVA 3D goes further, being free of BPA, BPS, latex, PVC, and phthalates. If you have any material sensitivities or allergies, checking the ingredient list is worth the effort. Most reputable brands clearly state their material safety certifications on the packaging.

Upper vs Lower Teeth Placement

Most guards are designed for upper teeth, but some like the DenTek Comfort-Fit are specifically made for lower teeth. Lower guards can feel less intrusive because they sit below your tongue, but they may shift more during sleep. Upper guards tend to stay in place better and are what most dentists recommend. If you have tried one type and found it uncomfortable, trying the opposite placement can make a surprising difference.

Dealing with Gag Reflex

This is one of the most common reasons people abandon night guards, yet most guides barely mention it. If you have a sensitive gag reflex, start with a low-profile guard like Plackers or the slim GOYO design. Front-tooth-only guards like SmartGuard also tend to trigger gag reflex less because they do not extend as far back in your mouth. Gradually increasing wear time from 30 minutes to a full night can help your body adjust.

HSA and FSA Eligibility

Many night guards qualify for HSA and FSA reimbursement, which can significantly reduce your out-of-pocket cost. Custom guards from enCore are typically eligible since they are considered medical dental devices. Check with your specific plan administrator to confirm eligibility, and save your receipt and any documentation from the purchase for reimbursement claims.

Dental Appliance Compatibility

If you wear Invisalign, retainers, or have a palatal expander, not all night guards will work for you. The SOVA 3D specifically notes compatibility with orthodontic appliances. For Invisalign users, you generally need to remove your aligners before inserting a night guard, and you should consult your orthodontist about timing. Some people find that wearing a night guard over their final Invisalign tray works in a pinch, but this is not officially recommended by aligner manufacturers.

FAQs

Final Thoughts on the Best Night Guards for Teeth Grinding

Protecting your teeth from nighttime grinding does not have to be complicated or expensive. After reviewing 12 of the top options available, the enCore Custom Dental Night Guard stands out as the best overall choice for its professional lab quality at a fraction of the dental office cost. For those who want immediate, no-fuss protection, the Plackers Grind No More delivers unmatched convenience. And for budget-conscious shoppers, the DenTek Professional-Fit has earned its status as the number one OTC dental guard for good reason.

The most important thing is to start using something rather than nothing. Every night you go without protection, bruxism continues to wear down your enamel, strain your jaw muscles, and potentially crack your teeth. Whether you choose a custom guard, a boil-and-bite option, or a disposable ready-to-wear design, taking action now can save you significant dental work and expense down the road. Your teeth will thank you for making this decision in 2026.
