Like many of the other manufacturers, the brand will make free alterations and even cover the shipping costs of sending yours back and forth until you are 100% happy with your mouth guard.

Though there are four different thicknesses, these don’t vary as much as some of the other brands. The options are all between 2mm and 3mm. Some brands, such as our editor’s choice, are 1.5mm-4mm. This is a good OTC mouth guard for grinding teeth but may not be as suitable for very heavy grinders.

Extra features: FDA-approved, latex-free, BPA-free; features a hybrid design with a tough acrylic outer and soft, comfortable inner layer

VIEW ON AMAZON

Many of the designs for mouth guards for grinding teeth are quite similar. They may not be the most comfortable. The American DentalCraft Dental Night Guard for Sleeping is designed in a different way and earns its nomination of the most comfortable mouth guard on the market.

The clever hybrid design has an acrylic layer on the outside to give the actual protection, but a cushioning, softer layer is much kinder on the teeth. This is a very clever design and can make it less of an annoyance having to wear a mouth guard at all.

The brand claims that people using this mouth guard see benefits with TMJ clicking, tinnitus and shoulder pain as well as dental related issues.

The thickness of 2mm is about right for those who want a night mouth guard for grinding teeth or who grind a moderate amount. If you are a heavy grinder, look elsewhere for something with a little bit more protection. 3-4 mm is better if your bruxism is severe.

The price is good, and it is certainly very comfortable, plus the process of sending off your impression to get your mouth guard made is relatively easy.

Pros
  • More comfortable than a lot of the other teeth grinding mouth guards
  • Easy to make an impression and send back

The Armor Guard Mouth makes our list based on the fact that it allows you to choose between two flexible materials in order to find the one which suits your condition best. Not many guards allow you to choose between actual materials as opposed to thicknesses.

The soft and flexible material they offer is available in a clear design and is suitable for light or even moderate grinders who don’t suffer with additional symptoms as a result of bruxism such as headaches. The second material is cloudy, and has a harder design which is designed to suit heavy grinders who experience teeth pain or other symptoms as a result of their teeth grinding issues.

On top of this, this is a design which can allow you to make an impression for men, women and children. Size won’t be an issue.

You can choose the thickness, too – 2mm, 2.5mm, or 3mm are available.

This is a well-designed, affordable option for light or moderate teeth grinders. The SmartGuard Elite Dental Guard is a mold-at-home option which means you may not get the same care and professional attention. You’ll need to create the mold yourself, and this can present something of a challenge.

However, this isn’t too difficult, instructions are included, and the SmartGuard is cleverly made. It is designed to keep the back teeth apart, and this prevents clenching of the jaw. This can mean you don’t grind as much as you did beforehand.

The pack is sold with two guards which means even if you don’t get it right the first time you can have another try at the mold. Or, you can have a reserve or backup mold.

This is a very affordable option for those who grind their teeth, and though there is some sacrifice in build quality and customizable features, it still does a good job of relieving your bruxism or TMJ.

The guards come with a one-year guarantee of satisfaction. The price is very reasonable and there is a lot to like about this option, especially if you only suffer moderately with bruxism.

Pros
  • Very affordable option
  • No need to wait for customized option to be sent to you
  • Comfortable inner layer makes long term wearing more tolerable
Cons
  • Not as customizable as some others
  • No choice of thicknesses
  • Not as good as some as the other options due to lower build-quality
  • Alterations aren’t possible once you’ve created the mold

Benefits of using a mouth guard for teeth grinding

6 Best Mouth Guards for Teeth Grinding to Help Treat Sleep BruxismIf you experience teeth grinding, it can be incredibly frustrating. The benefits of a mouth guard can be very far-reaching. If they are cleverly designed, they can reduce the amount of grinding you do as a result of your bruxism. On top of this, good quality guards can relieve you from many of the symptoms and conditions which can come from your grinding.

Many people experience TMJ, headaches, tooth pain and tooth wear as a result of grinding. Heavy grinders, in particular, can experience a huge amount of pain and a variety of ailments. It can be tough to get to the root of why you are grinding, so a mouth guard is your main protection.

Grinding your teeth can also be very frustrating if you share a bed. The noise can cost your partner sleep as well as adding a lot of pain to your day-to-day life. A guard can prevent a lot of the noise.

Features to consider when choosing a dental mouth guard

The following features are the most vital when it comes to choosing a mouth guard for your specific needs and the severity of your bruxism and teeth-grinding. We’ve based our product reviews on the features listed below, and it helps to understand why these features are so vitally important. This will ultimately lead to you making the right buying decision.

Is it moldable?

Everyone’s teeth are different. Historically, there have been a lot of over the counter options which are not moldable at all. This provides a huge issue as they tend not to be very comfortable. Think of a pair of jeans which feels very tight or ill-fitting. With teeth, it can be even worse.

If you buy an uncomfortable guard for grinding teeth, it will likely end up unused. It can prevent you from getting a good night’s sleep.

If you are looking for a really comfortable option, the American DentalCraft Dental Night Guard for Sleeping has been named our most comfortable mouth guard as it has two layers, one which cushions the teeth.

A moldable option is likely to cost more, but it will be more effective and less of a pain to wear. Investing in a molded mouth guard upfront can be the right thing to do in the long term. Most of the options on this list are molded. The ‘boil and bite’ options which are designed to be molded at home don’t tend to be as reliable, but most of the options on this list allow you to create an impression of your teeth and then send it to the manufacturer to be created for your mouth.

Material(s) and flexibility

Different manufacturers have a different way of doing things. Some have a double layer so that the rigid layer can provide protection and a softer layer give a bit more comfort. Silicone is often used in the design, but it is often a hybrid blend of different materials.

Unless you have allergies, this isn’t too much of an issue. The design should be BPA-free, latex-free and FDA approved so you know that you are putting something safe in your mouth. If the product has ADA approval (American Dental Association), this is even better.

Thickness

Different thicknesses can suit different people. It depends on how severe your teeth grinding is. Generally speaking, the thicker the guard, the more protection it gives for heavier grinding. A lot of the options give you multiple choices for what thickness you need. For instance, our Editor’s Choice product, the J&S Dental Lab Custom Dental Mouth Guard, has sizes between 1.5mm and 4mm.

If you are a light grinder you can probably use a 1.5mm or 2mm thickness guard, which is also suitable for daytime use and doesn’t interfere with talking and the like as much.
The best mouth guard for grinding teeth heavily will probably be 3-4mm in thickness. It is about matching up your own specific requirements and the symptoms and ailments you deal with as a result of bruxism or teeth grinding.

Upper vs. lower mouth guards

6 Best Mouth Guards for Teeth Grinding to Help Treat Sleep BruxismThough there is no definitive answer for whether upper or lower mouth guards are more effective, lower mouth guards tend to be a little more common and easily available. Though there are options for both, it boils down to personal preference. Either will do the job of stopping your teeth from grinding together if the guard is well made.

Some people opt for both! There’s no reason you can’t guard both but it might be a little uncomfortable.

How to use a night mouth guard for grinding teeth

Using your guard will involve creating the perfect mold first and foremost. You need to follow the instructions within the packaging to create the mold. This can involve creating an impression and sending it back to the manufacturers to create the guard itself.

If you don’t opt for a specific manufacturer which creates the guards based on an impression, you can use ‘boil and bite’ options. These are heated and then carefully bitten into in order to create a mold suited to your own teeth. These tend to be less scientific and less perfect.

Once you’ve done this, your guard will ideally clip nicely and snugly in place. It might take some time to get used to and you may even find it sets off your gag reflex initially. It shouldn’t take too long to get used to, but if it is still uncomfortable you may need to seek alterations or a different model of mouth guard. Some options such as the Chomper Labs Custom Dental Lab Made Night Guard even allow free alterations.

FAQ

Obviously, it depends on the thickness and the severity of your grinding. The J&S option, our editor’s choice, can last around 5 years if treated right. Other, more affordable options may only last you a year or so. Pay attention to the warranty or guarantee on offer by the manufacturers.

Yes, mouth guards are suitable for children but you need to make sure you get a small mold size. Many of the mouth guards out there send you multiple mold kits so you can make a small mold if you need to.

You can choose between a few methods of cleaning. You can use a toothbrush, preferably with soft bristles, to clean your mouth guard. You can get specific non-alcohol based cleaning solutions. Alternatively, you can soak it in hydrogen peroxide to disinfect.

Our Verdict

The J&S Dental Lab Custom Dental Mouth Guard is our top choice. This is a fantastic option for those who grind their teeth and it is exceptionally well-reviewed. We’ve given it 9.9/10 due to its reliability and customizable molds, it is also available in a lot of sizes.
