9 Best Night Guards  [Tested and Reviewed]

9 Best Night Guards [Tested and Reviewed]

Night guards are essential for individuals suffering from teeth grinding, also known as bruxism, especially during sleep. These guards can be custom-made at dental clinics or self-molded from over-the-counter options, which come as full-fit or partial mouthguards. A common concern is whether an over-the-counter night guard can offer the same level of comfort and durability as its professionally made counterpart.

In our latest review, the mybest team explored nine leading night guard products, selecting from the newest and most popular items offered by various manufacturers. Our evaluation focused on four critical aspects to ensure you get the most reliable advice for your needs. We're excited to share our findings in a ranked list of recommended night guards.


At mybest, we think the ideal night guard should be straightforward to mold, remain comfortable throughout the night, and be durable enough for long-term use. We have designed this guide so that you can shop for the right night guard in confidence that supports you in both comfort and dental health.

OTC Products Are Affordable, but Typically Recommended for Short-term Use

OTC Products Are Affordable, but Typically Recommended for Short-term Use

A night guard serves as a protective shield for your teeth, minimizing the wear and potential jaw damage from nightly clenching and grinding. The sticker shock of a dentist-made night guard can send many searching for alternatives, leading them to the more affordable and readily available over-the-counter (OTC) options.


The appeal of OTC night guards lies in their cost-effectiveness and convenience. However, the DIY nature of molding these guards can lead to a less-than-perfect fit. Using a poorly fitted guard over time may not just fail to prevent teeth grinding but could also worsen dental misalignment or even trigger temporomandibular joint (TMJ) disorder. This is why long-term reliance on these guards isn't advised.


OTC night guards should ideally be a stopgap solution, used for short periods, such as a week, by those who can't immediately visit a dentist or are experimenting with a store-bought solution. If you're experiencing chronic teeth grinding or symptoms like headaches, shoulder stiffness, or jaw pain, it's crucial to consult with a dental professional for a long-term solution rather than settling for a quick, over-the-counter fix.

Suguro Tsujimura
Dentist, President of the IDHA

The pressure on your teeth when you grind or clench them is said to be 2 to 5 times your body weight. It's easy to imagine that if this pressure is applied while using a night guard that doesn't fit your dental alignment or jaw, it could cause changes to your jaw or teeth.


Although many over-the-counter night guards are labeled with a recommended use period of 6 months, usage should be limited to 1 to 2 weeks at most.

This product holds a patent for its two-layered structure and slanted front design as a night guard. It's highly durable and crafted in such a way that reduces discomfort in the mouth, coming closest to our definition of the ideal night guard - "easy to mold, comfortable to wear with no discomfort, and can be worn all night." At its price point under $15, is also cheaper than many other products, making it perfect for those who want to give it a try.

How to Choose Night Guards

Here are the points to keep in mind when choosing the best Night Guards.

1

Choose a Night Guard That Covers All Teeth to Reduce the Burden on the Molars

Choose a Night Guard That Covers All Teeth to Reduce the Burden on the Molars

OTC night guards vary in the area of teeth they cover: some are designed for all teeth, some exclusively for the front teeth, and others just for the molars. To effectively reduce the strain from clenching or grinding, a guard that covers all your teeth is generally recommended.


This recommendation stems from the fact that the human bite force peaks at the molars, which endure the brunt of grinding and clenching. Opting for an all-teeth type or a front-teeth type ensures the mouthguard shields the front teeth, creating a barrier that lessens the force on your molars.


However, it's important to exercise caution with the more compact front-teeth types. Without full contact between the top and bottom teeth, there's a risk of shifting teeth positions, potentially misaligning your bite.


On the flip side, choosing a molar-specific guard might inadvertently facilitate more force on these teeth, possibly encouraging more clenching. In my own experience, wearing a molar-type guard led to a night filled with dreams of chewing gum, highlighting how partial guards can prompt unnatural jaw alignment and pose significant risks to oral health. Given these considerations, the all-teeth type emerges as the safest bet for comprehensive protection.

Suguro Tsujimura
Dentist, President of the IDHA
Suguro Tsujimura

If more stress than usual is placed on the molars, they can be compressed and sink. Therefore, to avoid the risk of interference between the top and bottom front teeth, it's recommended to prioritize purchasing a night guard set that covers all of the teeth.

Ayuka Yokoyama
Head of Personal Care Products at mybest

The front-tooth and molar type is compact and reduces discomfort in the mouth, but there's a risk of it coming off and causing suffocation during sleep.


The full-teeth type is somewhat larger, and you might feel some discomfort when you first start using it, but considering the strain on the teeth, it's better to choose the full-teeth type.


I'll explain some points that can affect how they fit below, so please refer to that.

2

Choose a Low-Rimmed and Thin Guard to Lessen Mouth Discomfort

Choose a Low-Rimmed and Thin Guard to Lessen Mouth Discomfort

Opting for a low-profile, thin night guard is key to uninterrupted, comfortable sleep. A guard with a slim edge won't irritate your gums and allows for a more natural mouth closure, minimizing discomfort. Conversely, a night guard with a thick, high edge can feel bulky against the gums, potentially causing stress as you try to drift off to sleep.


Imagine wearing a bulky guard and trying to settle down for the night; the discomfort from the guard pressing against your gums and cheeks could make falling asleep a challenge. Feedback from one of our testers who endured a night with such a guard included, "Because the night guard is thick, it stretched the inside of my lips, and I woke up feeling like my mouth had been wide open all night."


However, when it comes to the durability of a night guard, our findings suggest that the material of the guard plays a more significant role than its thickness. This means you don't have to compromise on comfort by choosing a thicker model for the sake of longevity. A slim, comfortable guard made from durable material offers the best of both worlds: protection without discomfort.

Suguro Tsujimura
Dentist, President of the IDHA

Some over-the-counter night guards allow you to adjust the size by cutting or filing the edges yourself. Partial self-adjustment won't significantly damage your dental health, but you should avoid actions that could cause injury to the oral mucosa with sharp edges, or actions that could distort the night guard.

3

Check the Ease of Shaping the Mold

Check the Ease of Shaping the Mold

A well-executed molding process is the cornerstone of a comfortable fit for a night guard. For those who might not be confident in their molding skills or are trying this for the first time, opting for a night guard that comes with a pre-formed mold can be a game-changer.


These pre-formed types are designed with an edge that allows for minor adjustments using just your fingers, making the process more forgiving. The advantage here is that the outcome doesn't heavily rely on your manual dexterity, and you're more likely to achieve a smooth finish with uniform thickness throughout the guard.


Conversely, night guards that require molding from a flat state demand a higher level of precision. You'll need to shape the edges carefully with your fingers, adapting the guard to fit your teeth's unique alignment. Speaking from experience, even with a relatively steady hand, I found myself ending up with a guard that had distortions and uneven thickness in places.


For those new to night guards or who have struggled with the molding process in the past, selecting a pre-formed type can simplify achieving that all-important comfortable fit.

Not only for this test, but also from my experience of forming OTC night guards numerous times up to now, let me teach you some tricks to mold it that are not mentioned in the instruction manual.


1. Thoroughly read the manual and rehearse: It's a race against time once the night guard is softened in hot water!

2. Since it is used with your mouth closed, don't be afraid to bite down firmly.

3. After biting, pinch both the front and back of your teeth firmly with your fingers to conform to the dental arch.

It's a must to meticulously shape it to achieve a comfortable fit that does not cause discomfort.

4

Soft Plastic Material and Double Layers Can Make the Guard Relatively Hard to Break

Soft Plastic Material and Double Layers Can Make the Guard Relatively Hard to Break

When it comes to night guard materials, you'll generally find two options: silicone and plastic. While over-the-counter night guards are typically a short-term solution, meant for use within a 1 or 2-week period, those seeking a more durable option should consider a double-structured design. These designs combine soft and hard layers of plastic material, offering enhanced durability.


In our durability tests, we simulated real-life use by clamping a molded night guard onto a tooth-shaped form and applying a significant load of 165 pounds. We then measured the change in thickness before and after the test. The results revealed that night guards made from soft plastic material experienced an average thickness reduction of 8%, significantly less than the 23% reduction observed in hard plastic types.


The findings suggest that a double-layered construction, featuring both soft and hard plastic materials, offers greater durability. This is particularly relevant for individuals who exhibit strong teeth clenching and grinding habits. If durability is a key factor in your decision-making, opting for a double-layered plastic night guard might be the best choice.

A Low Rim and Easy-To-Mold Shape Creates “Advanced Comfort”

What we loved

  • Low profile without sacrificing durability
  • Pre-shaped design reduces need for molding
  • Durability against high pressure

What we didn't love

  • Nothing in particular.

Our top pick, the NIGHTGUARD Advanced Comfort by The Doctor's, stands out for its sleep-friendly design. Its double-layered soft plastic construction, with a patent-pending design that envelops all teeth and features a sleek edge around the front teeth, is particularly noteworthy.


The low and thin edging of this night guard significantly reduces oral discomfort, making it an excellent choice. The minimized height between the front teeth and the upper lip enhances comfort by allowing for a natural mouth closure.


One of the best features is its pre-shaped design, eliminating the need for intricate molding with your fingers. Testers who have worn it overnight have praised its fit, noting, "It molded very well to my teeth, making the night guard almost imperceptible."


Durability tests further confirmed its excellence, showing only a 3.5% dent under a 40-minute, 165 lb load. The innovative division of the double-layered soft plastic into a hard and soft layer contributes to its high durability. Thus, the NIGHTGUARD Advanced Comfort is a standout product, meeting the needs of both newcomers to OTC night guards and those who have been in search of the perfect fit for a long time.

Easy to Shape, Secure Fit

What we loved

  • Can be molded at lower temperatures
  • Low and thin edges
  • Comfortable

What we didn't love

  • Has a tendency to shrink

The SleepRight ProRx Custom Dental Guard offers a full-coverage solution with a distinctive advantage in its molding process. Unlike typical night guards that require boiling water for molding, this product can be molded at a lower temperature, specifically at 150°F. This feature significantly reduces the risk of burns, making the molding process safer and more comfortable.


The ease of molding with this guard is particularly commendable. It transitions from white to transparent in hot water, signaling it's ready to be molded to your teeth alignment. This intuitive design simplifies achieving a snug fit, a major plus for users.


Another advantage is the guard's low and thin edges, which contribute to its almost unnoticeable presence during sleep, as reported by testers who found it lightweight and comfortable in various sleeping positions. However, a slight drawback is its tendency to shrink a bit after molding, potentially causing a tighter fit that might not be ideal for individuals prone to headaches.


Durability tests revealed a 16.1% dent under a 40-minute load of 165 lbs, which poses questions about its long-term resilience. Despite this, the SleepRight ProRx Custom Dental Guard stands out for those in immediate need of a comfortably fitting night guard, offering a temporary solution until a more permanent one can be obtained from a dentist.

High Durability and Minty Scent to Boot

What we loved

  • Refreshing minty scent
  • Exceptional strength and resilience
  • Easy molding

What we didn't love

  • Doesn’t provide a flawless fit
  • Thicker than some alternatives

The Oral-B Nighttime Dental Guard stands out not just for its full-coverage protection but also for its unique mint scent, adding a refreshing feel to the mouth during use. This feature is especially appreciated by those looking for a more pleasant night guard experience.


Durability is where this product really shines. In tests involving a pull of 165 lbs, the Oral-B guard demonstrated exceptional strength, showing no signs of caving in. This resilience makes it an excellent choice for individuals who may need to use their night guard beyond the typical 1-2 week period suggested for over-the-counter options.


Ease of molding is another significant benefit. Thanks to the included container, this pre-set guard simplifies the molding process. Users simply bite down without the need for detailed shaping with fingers, ideal for those who might not be as manually adept.


The testers also praised the comfort level, noting that the guard's thickness was just right, allowing for natural mouth closure. While it may not provide a flawless, bespoke fit, the Oral-B Nighttime Dental Guard offers a compelling combination of durability, ease of use, and comfort at an accessible price point, making it a worthy consideration for anyone in the market for an OTC night guard.

Minimal Discomfort but Risk of Clenching

What we loved

  • Less mouth feel compared to some others

What we didn't love

  • Risk for falling out
  • Presents a choking hazard

The ULTIMATE DENTAL GUARD by DENTEK is uniquely designed to cover only the back teeth, offering a compact and minimalistic approach to nighttime dental protection. This design choice allows for the convenience of being able to drink and speak even while wearing the guard.


One of the standout features of this product is its use of minimal material, combined with a low edge that avoids contact with the gums, significantly reducing the potential for oral discomfort. Testers have reported being able to close their mouths naturally and experiencing no gum pain, highlighting the comfort and ease of wearing this guard overnight.


The inclusion of a pre-shaped mold simplifies the molding process, making it user-friendly for anyone. This feature, along with its minimal presence, makes it an attractive option for individuals sensitive to the feeling of having a foreign object in their mouth.


Durability tests involving a 165 lb load for 40 minutes revealed a minimal dent rate of just 2%, showcasing the product's robustness. However, it's important to note that because this guard focuses on the back teeth, there's a risk of it becoming dislodged during sleep. Additionally, its design might inadvertently encourage clenching of the back teeth, potentially leading to a looser fit over time and posing a choking hazard.

Little Discomfort, but Hard to Close Mouth

What we loved

  • Reduces damage to front teeth rather than molars

What we didn't love

  • Covers a smaller area compared to others
  • Requires boiling water to fully mold

The Brux Night Guard by BNG focuses on protecting the front teeth, a strategy aimed at reducing jaw damage by redistributing biting forces away from the molars to the front teeth.


This product has shown to possess adequate durability for short-term use, lasting about a week. In a rigorous durability test involving 165 lb. load for 40 minutes, the night guard exhibited a minimal indentation of 4.4%, indicating its resilience. Its compact design covering only a small area of the teeth helps minimize oral discomfort by reducing unnecessary contact with the gums and cheeks.


Despite these benefits, the guard's significant thickness and size might cause some issues, with testers reporting difficulties in sleeping with their mouths closed, leading to dry mouth upon waking. Its design, focusing only on the front teeth, also means it's more prone to dislodging during sleep, which could pose a choking hazard.


While the Brux Night Guard comes pre-molded, the necessity of using boiling water for the molding process might not appeal to those looking for a quick and easy setup. Coupled with its higher price point, this night guard may not be the first choice for everyone. However, for individuals experiencing particular discomfort with guards that cover the molars it could offer a suitable alternative worth considering.

Durable, but Can Feel Bulky

What we loved

  • Set of five with various sizes
  • Robust and durable

What we didn't love

  • Some feel the mold is too loose

The ConfiDental's Sapphire night guard from The ConfiDental offers full coverage for all teeth and includes a set of five guards, allowing users to choose the thickness based on their level of teeth grinding or even for use as an athletic mouthpiece. The thin type, in particular, received high marks for its performance.


Crafted from soft plastic material, this product demonstrates notable durability. In a test applying a 165 lb load for 40 minutes, it exhibited only a 2.9% indentation, showcasing its robustness. The pre-molded design also means it can provide a reasonably good fit straight out of the box, simplifying the molding process.


However, the guard's high edges and the broad base designed to accommodate tooth shapes mean that adjusting it for a perfect fit can require some finesse. Some testers have reported issues, mentioning, "The mold was very loose, and the front was too thick and high, making it feel like my mouth was stuffed."


For those in need of a versatile solution that can serve as both an athletic mouthpiece and a guard against varying levels of teeth grinding—potentially influenced by daily stress—the ConfiDental's Sapphire might be a suitable option to consider, despite some of the challenges in achieving the perfect fit.

A Mood-Boosting Pop Design with a Finicky Fit

What we loved

  • No need for boiling water
  • Snug fit with proper shaping

What we didn't love

  • Durability not as robust as others
  • Not built for longevity

The Custmbite Kloud Night Guard offers full coverage for all teeth and simplifies the molding process without the need for boiling water. Instead, users can mold the guard using just a microwave, paper towel, and plate, accompanied by clear instructions and a pre-existing mold for an easy-to-follow setup.


Despite its user-friendly design, the high edges of the guard require careful attention during the molding process to ensure a snug fit. While its thin design generally allows for easy mouth closure, improper shaping can lead to complaints of looseness and discomfort due to the guard's tightness at the high edges.


One concern with the Custmbite Kloud Night Guard is its durability. In tests involving a 165 lb. load for 40 minutes, it showed a considerable indentation of about 24.3%, highlighting its vulnerability to damage, especially for those with a strong teeth-grinding habit. Made from a soft material, the guard runs the risk of breaking under intense pressure.


Given these considerations, while the Custmbite Kloud Night Guard presents an accessible option for those looking for an easy-to-mold solution, its potential durability issues suggest it may not be the best choice for individuals with severe teeth grinding. Those concerned about the longevity and effectiveness of their night guard might need to explore alternative options.

Not Great for Smaller Mouths

What we loved

  • Two-layer material
  • Pre-molded design for easy fitting

What we didn't love

  • Size can make it difficult to close mouth

The DENTEK PROFESSIONAL FIT DENTAL GUARD offers full dental coverage and comes with a molding tray, boasting a fit that rivals that of custom-made night guards from dental clinics.


Constructed from a two-layer soft plastic material, this guard demonstrates commendable durability. In a robustness test involving a 165lb load for 40 minutes, it exhibited minimal compression of about 6.1%, suggesting it can maintain its integrity for roughly a week with no significant issues. The pre-molded design is another plus, simplifying the fitting process for users without requiring advanced manual skills.


Despite these strengths, the guard's thickness poses a challenge for comfort, particularly due to the bulky area beneath the front teeth. This has led to feedback from some testers stating, "The night guard was too big, and I couldn't close my mouth all the way." Consequently, individuals with smaller mouths or those who prefer a slimmer profile may find this product less accommodating to their needs.

Difficult to Shape, Questionable Durability

What we loved

  • Not as bulky as some other options

What we didn't love

  • Dented more than others during testing
  • Requires skillful shaping to get a good fit

The Sova Aero Night Guard covers all teeth and is distinguished by its design, which incorporates perforations to ensure that breathing is not hindered and allows for drinking while in use.


Its design aims for minimal bulkiness with low, thin edges, yet the use of hard plastic can lead to discomfort, particularly when the guard presses against the gums or cheeks while lying down. This guard requires manual shaping starting from a flat form, a process that some testers have found challenging, with feedback such as, "It was hard to mold and get the perfect fit by delicately folding the walls."


The durability of the material raises additional concerns. In a test applying a 165 lb load for 40 minutes, the night guard showed a significant dent of about 29.3%, indicating that it may not withstand heavy use. Coupled with a relatively high price tag of $25, the Sova Aero Night Guard's discomfort and questionable durability suggest it may not be the best investment for those seeking a comfortable and long-lasting solution for night-time teeth protection.

Comfort During Use

Comfort During Use

We determined the standard for a product that excels in comfort during use and greatly satisfies users as "one that is evaluated by testers suffering from bruxism as having no discomfort during use."

Scoring Method

We evaluated the comfort level of wearing the night guard—after the testers themselves molded—overnight. We then rated the recommendability of each product and converted this into a score.

Test Conditions

  • Testers: Men and women troubled by teeth-grinding

  • Each tester molded a night guard according to the instruction manual

  • After wearing, they laid on their back (for 30 seconds) and sideways (for 30 seconds)

  • Wore each night guard for more than 7 hours

What We Checked

  • Is there any discomfort in the mouth?

  • Do the teeth fit well?

  • Does it feel suffocating while wearing it?

  • Was it possible to fall asleep easily?

We determined the standard for products that excel in comfort after use and satisfy users as "ones evaluated by testers suffering from bruxism as having no discomfort after use."

Scoring Method

We evaluated the comfort of each night guard by having our tester mold it themselves, wear it overnight, and assess any discomfort after use. Each product's recommendation level was then scored.

Test Conditions

  • Testers: Men and women troubled by teeth-grinding

  • Each tester molded a night guard according to the instruction manual

  • After wearing, they laid on their back (for 30 seconds) and sideways (for 30 seconds)

  • Wore each night guard for more than 7 hours

What We Checked

  • After removing the night guard in the morning, is there any discomfort in the mouth?

Durability

Durability

We established the standard for a product that would greatly satisfy users due to its superior durability as "a product that, even when burdened, experiences minimal impact on its shape and appears to be usable in the long term."

Scoring Method

A 165 lb. load is applied to the night guard that is set in the shape of teeth. Considering that teeth grinding occurs intermittently for about 40 minutes during 8 hours of sleep, it is conducted for a total of 40 minutes with breaks every 10 minutes. The durability of the night guard was assessed and scored based on how little the thickness was reduced before and after the load was applied. If the reduction in thickness is small, the nightguard is considered to be more durable.

Test Conditions

    • Place the formed night guard on the scale, clamp it so that it is under a load of 165 lb

    • While setting intervals to release the load every 10 minutes, apply the load for a total of 40 minutes per product
