The Ten Best Mouth Guards for Grinding Teeth
According to the professional dentists and sleeping experts, there are a few unsurpassed best mouth guards for grinding teeth that are perfect for your teeth. In this article, we have listed the top ten best mouth guard for grinding teeth which you can choose and use it to get a perfect life back.
1 – Neomen Professional Dental Guard (Best Pick 🥇)
The Neomen guard is top on our list because the price is fantastic and the quality isn’t compromised. Conveniently, the pack includes 4 guards in 2 different sizes. These guards are made using the “boil-and-bite” method – something you’ll see a lot of on this list.
Boil-and-bite simply means that you boil the guard to make it soft before biting into it to make your permanent dental impression. Now you have a guard that fits exactly to your teeth. The material is moldable so that it forms around your pearly whites for a tailored fit.
As an added bonus, you can also use these guards as whitening trays. A case for storing is included with the pack so you can keep your guard clean, dry, and in good condition. You can opt to make both top and bottom molds, although many people find that just a top guard works fine. If you decide to do this, you’ll have a second guard in the same size when your first one wears out.
The antibacterial case is important because you want to keep your guard perfectly clean. Remember – there’s loads of bacteria in the mouth, so you want to keep your guard meticulously clean to avoid odor and keep good dental hygiene.

A simple buying guide to determine the best mouth guard for grinding teeth
A small overview with all the insights you need to know when buying a mouth guard for teeth grinding.
What to pay attention to when buying this product
Now that you’re well-versed in some of the best guards, you might be wondering which is the winner for you? Below, we take a look at some additional considerations including benefits and disadvantages of mouth guards.
Boil and bite or custom impressions
Many of the guards you can purchase outside of the dentist’s office are one-size. You can trim them if necessary and then use the boil-and-bite method to mold the guard to your mouth. Also known as the heat, shape and wear method.
But if your grinding and clenching are severe, it’s usually recommended that you get a mouth guard that’s tailored for your mouth by a professional. A guard like the Pro Teeth Custom Guard is a good example of an exact-fit custom guard that leaves nothing to chance.
With professional impressions, there is more cost and a considerable time investment involved. And depending on the manufacturer, you could be in for a bit of a wait before you receive your guard. However, most dentists say this kind of guard is vastly superior to a boil-and-bite.
There’s a huge range of cost when it comes to mouth guards. The guards made from your dental impressions could run as high as $500-$800. On the other hand, many people are fully satisfied with guards they purchased from the store for less than $50.
When people have severe issues resulting from bruxism, it can be worth it to invest in one of the higher-end guards. But you could always try one of the inexpensive ones first to make sure you don’t have issues with a wearable dental device. In rare cases, guards are problematic and cause new pain and irritation, so some trial and error might be in order.
We all know that when something adds difficulty to our daily routine, we quickly lose our patience with it. Some mouth guards are very simple to clean and others are pretty involved. Sometimes small annoyances can keep us from doing things that are good for us, so do some research on which guards are reasonably simple to clean and keep in good shape.
There are some pretty interesting variations in the world of mouth guards. While many cover all of your teeth, some only cover your molars and a few are bite-pads that go between your last set of teeth. Likewise, some people wear both top and bottom guards while many prefer to wear just one.
If you’re incredibly sensitive to the way things feel or you have particularly sensitive areas in your mouth – gums, teeth, or tongue – you might want one of the less invasive guards like the DenTek Comfort Fit mouth guard.
We know you’re used to examining the materials just about any time you make a purchase. But this could never be more important than when something will be sitting in your mouth all night long. Look for mouth guards that specify on the package that they are BPA-free. BPA is a known toxic chemical and it’s best to avoid it at all costs. Another thing you’ll commonly see on mouth guard packaging are the words “latex free.” The reason you want to avoid latex in a nighttime mouth guard is that many people have a latex allergy.
Even if you aren’t sure whether you’re allergic, avoiding latex is a safe bet. Latex allergies can cause itchy skin, hives and even anaphylaxis (possibly life-threatening swelling of the throat), so it’s definitely better to be safe than sorry when it comes to this ingredient!
Advantages of a mouth guard for grinding teeth
It’s usually a dentist that recognizes the need for a night mouth guard. While they’re up close and personal with your teeth, they can see the signs of unnatural wear and tear on your enamel. Usually, they’re the ones to suggest a guard to prevent further damage.
Below, we take a look at some of the specific advantages of a mouth guard for tooth grinding.
Saving Your Teeth
Although a mouth guard won’t stop you from clenching and grinding your teeth, it will prevent further damage to your teeth and minimize the effects and impact of these habits. Having a guard in place will keep you from further damaging your tooth enamel or causing cracking or chipping. Commonly, people with sleep bruxism will use their bottom front teeth to push hard against the back of their front teeth. Mouth guards stop this action from occurring.
By wearing a mouth guard, you can improve your own sleep habits and patterns. The noise, tension, and pain from clenching and tooth grinding can definitely disrupt your sleep and compromise its quality.
This can also disrupt the sleep quality of anyone who happens to be in the same room!
The addition of a mouth guard to your nightly routine can improve your bedtime experience all-around. Coincidentally, getting enough quality sleep helps ease anxiety, tension and headaches.
Many people will bruxism suffer from morning headaches. After a night of clenching and grinding, the pressure can wreak havoc. Mouth guards can help minimize or even eliminate these kinds of tension headaches.
TMJ (Temporomandibular Joint)
TMJ is a sometimes serious condition that causes pain and compromises jaw movement. In addition to causing pain, it can create a clicking sound and make it difficult to chew. Mouth guards worn at night can help with TMJ because clenching and grinding can make TMJ even worse over time.
Another thing that’s great about these guards is that they can be used for multiple practical purposes. If you play sports or engage in any physical activity like boxing, these guards can all double as a protective guard. And if you like to perform at-home tooth whitening, these nighttime mouth guards can serve as a teeth whitening tray.
Disadvantages of a mouth Guard for teeth clenching
Unfortunately, there’s good and bad to everything and mouth guards are no exception. There are a few common complaints about wearing a mouth guard at night. Below, we take a closer look.
In all honesty, it can be a hassle to worry about wearing your mouth guard every night. Night time is supposed to be for relaxing, resting getting a good night’s sleep. Putting in your mouth guard can feel disruptive or annoying. However, it’s worth noting that the inconvenience is short-lived for most people.
Advances over the years have resulted in extremely lightweight, non-invasive and comfortable mouth guards. Most people who benefit from them don’t mind the minor inconvenience of wearing them.
Sometimes guards are just a pain in the mouth. While some people are completely unbothered by them, others dread saying “ah” for these dental devices. That’s why it’s important to not just settle for any old mouth guard. Research specific items for their comfort and popularity.
A well-fitting mouth guard shouldn’t rub, irritate, or bother you in any way.
