Best Mouth Guard For Grinding and Teeth Clenching

This article goes in-depth to cover all night guard related topics. This includes types of night guards, costs, causes and concerns of bruxism, TMJ, wear instructions and proper routine cleaning.

The best mouth guard for teeth grinding and teeth clenching is a custom made night guard.

Why is a professional custom-made mouth guard for teeth grinding the preferred choice to help relieve symptoms of bruxism?

First! Let’s get clear on what bruxism is.

“What is Bruxism?”

Bruxism is excessive grinding of the teeth and/or excessive clenching of the jaw.

It is an oral parafunctional activity. This means, it is NOT an activity related to normal function such as eating or talking.

The need to find a mouth guard for grinding teeth is usually the result of teeth grinding and jaw clenching, also known as bruxism.

Bruxism is a super common problem. Reports of prevalence range from 8–31% in the general population.

Note* Sleep bruxism can be definitively diagnosed in a sleep laboratory by means of a costly test called polysomnographic recordings.

The Dental Night Guard for Teeth Grinding and Jaw Clenching

The custom dental night guard – also referred to as the occlusal guard, night guard, nocturnal bite plate, dental guard, night/mouth guard for teeth grinding, and “bite splint” – is an exact, custom-fit mouth guard for teeth grinding, made by taking dental impressions of your teeth.

Wearing a custom night guard protects the teeth from excessive wear and can relieve pain & discomfort in the teeth/jaw area(s).

A stone replica of your exact dental anatomy is then made from your impression. The difference between a custom made dental guard and a stock-type guard that you would buy over-the-counter is quite significant.

Stock Night Guard vs. Custom Made

The main problem with the “one size fits all” type is that mouths (in general) are not one size.

Ex: Men typically have bigger mouths than women.

A teenager vs an adult is going to be a completely different size. The arch of teeth can vary greatly from person to person.

Disappointment usually follows when you buy an over-the-counter type (even the boil & bite guards)

Store bought night guards are affordable but come with a slew of potential problems. The most common complaints include being “too bulky”, “uncomfortable to sleep in”, “falls out during the night”, wears down too quickly, etc.

“Do I really have to wear a night guard if I grind my teeth?”

If you are grinding/clenching your teeth night after night, you really do need to be wearing a night guard.

Your best bet is to get professionally fitted and have a custom night guard made from either a dental lab online or your local dental office.

If cost is an issue, you can go through an online night guard lab. By going this route, you can order directly through the night guard company.

“How does purchasing online work?”

After placing your order, the lab will ship out a do-it-yourself impression kit This impression kit consists of mixing putty and a plastic tray.

You take your own dental impression and mail it back to the company. Your custom night guard will be processed and shipped to you. Cost varies from company to company, but you can expect to pay somewhere between $100-$200 for a custom night guard for grinding teeth.

Be sure to choose an online lab that will work with you to make sure that you end up with the right guard.

Here at Sentinel Mouth Guards, we make sure you are completely satisfied with your purchase – or your money back! The Sentinel warranty and return policy is unlike any other.

We stand by our products and will always work with you to your absolute satisfaction. This means that if you are dissatisfied with your product for any reason, you can either contact Sentinel within 90 days for a full refund, or opt to continue working with us until you get a great fitting guard. Our commitment to you is 100% satisfaction.

Choosing to purchase through your local dental office will cost quite a bit more. Dental office prices GREATLY vary (average price can be from $400-$1200).

Finding the Type of Mouth Guard For Teeth Grinding and Clenching That Is Right For You

When you start to shop for a custom night guard, you may become confused about which one to choose.

How do you know if you need a hard type or a soft type? What exactly is a dual-laminated night guard? What if you grind your teeth during the day? Do you need to be wearing a day-time guard as well? And most importantly, will any of these guards be comfortable enough during sleep?

These are all important questions. We’ve noticed that people are searching the web for answers quite frequently but the information that is being put out there is often times conflicting and vague.

So how do you know if you need a hard night guard, a soft one or the dual laminate type?

Here’s the not-so-great news. Even dentists can’t all agree on which mouth guard for grinding teeth is better. A dentist can look at your teeth and tell you if you’re doing short or long term damage to your teeth.

Instinctively, you may also know if you’re doing some serious damage to your teeth. If you wake up every day (for instance) with mouth/jaw/teeth soreness and a headache, you should look into purchasing a night guard.

But wait! There is good news!

The good news is, any type of properly fitted, custom made night guard will protect your teeth from direct tooth on tooth contact, preventing teeth damage and effects that are associated with teeth grinding and/or jaw clenching (such as headaches, jaw pain, facial pain).

Tune into your body and evaluate your own teeth grinding habits. Are you in a lot of pain night after night? Is the pain in your teeth or jaw? Both? Are you cracking your teeth?

A thin 1mm night guard is a perfect discreet solution for daytime use.

Make a guided choice based on what you know about your own particular situation. Establishing what type of teeth grinder/jaw clencher you are (heavy, moderate or light) is a step in the right direction.

Let’s begin!

Different types of custom night guards

Sentinel Soft Night Guard

The Sentinel Soft Dental Night Guard Review

sentinel soft dental night guard

If you grind your teeth, you may be all too familiar with waking up in the morning with painful jaws and a headache.  So far, nothing protects your teeth more than a custom mouth guard. The mouth guard for teeth grinding is not like the typical sports mouth guard; rather it is a dental night guard. Among the available dental guards on the market, the soft night guard still stands as the most common type used.

A Soft Dental Mouth Guard for Grinding Teeth?

Types and features of soft dental night guard

There are two main types of the soft dental night guard. You have the over-the-counter (store bought) and the custom-made night guard.

Custom vs. store bought

The custom made night guard is a special guard that is professionally modified to fit the dental structure of the patient. This one will ensure that the teeth do not grind and that you sleep comfortably without any pain. The custom made guards are quite comfortable. They also help prevent the soreness, headaches, and jaw pain.

The store-bought night guards are manufactured in bulk to fit every type of person. Because these are mass-produced, they may not be as comfortable as the custom made. Most of the one size fits all guards have a default size and fit. Also, the material used is a lesser quality than the custom made dental night guards and wears down much quicker.

Pros and cons of the soft night guard

The Pros
The soft night guard tends to be the most comfortable. Even if you try grinding your teeth while you have the guard on, there is no way your teeth will be damaged. The custom made soft guards are designed to fit the exact structure of the teeth and are totally flexible. Compared to the hard and dual laminated guards, these tend to be more adaptable and easier to get used to.

The Cons
Though the soft dental guards are comfortable in the mouth, some people may innately want to clench or grind on the soft material. One study has shown that some of the patients using the soft dental guards will attempt to chew the guard and also may grind their teeth more often. Another negative is that the soft dental guard has a limited lifespan. Most of the companies (including Sentinel Mouth Guards) that develop the soft night guard will terminate their warranty after six months. The other types of dental guards are more stable and they can last for a longer time than the soft dental guards.

What are dentists saying about the soft night guard?
Regardless of the few flaws of the soft dental night guard, they are the most common type of guards on the market.

These night guards are recommended by many dentists due to their easy adaptability and high customer satisfaction rate. Dentists highly advise patients to go for the custom-made guards, so keep in mind that a soft custom-made night guard is still far superior to store-bought “one size fits all” guards.

Choosing a professionally custom made night guard helps to enhance the comfort and limit the grinding. The guard also feels more comfortable than over-the-counter guards.

The soft dental night guard is an excellent choice if you have teeth grinding or clenching issues when sleeping.

Key points about the soft guard

  • Still the most common type produced in dental offices
  • High customer satisfaction rate
  • Many customers believe the soft guard to be the most comfortable
  • This soft type has generally been the most common style of night guard produced in dental offices, but recent research has indicated that the soft material may actually encourage grinding or clenching by up to 50%. The cases that have been reported/studied show that this new revelation is more prevalent with the thicker stock or boil & bite guards (such as when a person buys an over-the-counter mouthguard and tries to conform it to their teeth). You should be aware of this risk when deciding on which guard to choose.
  • The professionally made custom soft guards are small & comfortable but may wear down a bit quicker than the dual-laminated and hard acrylic guards (depending on the degree of your grinding or clenching habits).
  • Sentinel Mouth Guard Co. offers a 6 month replacement warranty on this guard type in the event that you grind through your guard or it becomes defective.

Sentinel Hard Night Guard

The Sentinel Hard Dental Night Guard Review

custom mouth guard

The hard acrylic-like night guard is small & low profile, yet very durable.

It is generally recommended for moderate to extreme grinders/clenchers or persons suffering from TMJ.

Be aware that teeth may shift overtime. A hard, non flexible dental guard does not allow much “wiggle room” for ANY changes to the teeth.Keep this in mind when making your decision.

If you plan on having work done in the future that could change your dental anatomy (new crown, bridge, bonding, implants, veneers, even cavities being filled could alter your anatomy enough to change how your night guard fits) consider getting a night guard made for the opposing arch or choose a different (more adaptable) type.

In addition to wearing a hard night guard, you may need to seek additional treatment (if suffering from TMJ). In some cases, a special type of night guard that could involve ramps and/or metal clasps may need to be made by your dentist/TMJ specialist.

If you’re experiencing alignment issues or if you know you suffer from TMJ please consult with a dentist before ordering a night guard online.

Sentinel Mouthguards offers a 1 year replacement warranty on this guard type in the event that you grind through your guard or it becomes defective.

Hard night guard key points

  • non-flexible
  • durable
  • not bulky, snaps into place
  • can prevent teeth from shifting if worn consistently
  • Sentinel Mouth Guard Co. offers a 1-year replacement warranty on this guard type in the event that you grind through your guard or it becomes defective

Sentinel Dual-Laminated Night Guard

The Sentinel Dual Laminated Dental Night Guard Review

lower mouth guard for teeth grinding

This guard type is relatively new on the scene. It combines two layers of material (a soft inside and a hard acrylic outside).

It is a wee bit thicker than the hard acrylic guard. This nighttime guard can handle heavy jaw clenching/teeth grinding.

The soft plastic is comfortable against the teeth and the hard outside acts as a protective shell. Customer feedback has given us some insight into the preference of the general public.

We have found that most people are extremely happy with the fit of the dual laminated night guard.

Sentinel Mouth Guards Co. offers a 1-year replacement warranty on this guard type in the event that you grind through your guard or it becomes defective.

Pro tip: Sentinel Mouthguards. guarantees 100% satisfaction. If you choose a guard and you’re not happy with it, we will make you a different type, free of charge or your money back (within 90 days of purchase)

Dual Laminated Night Guard Key Points

  • Semi-flexible appliance
  • Rates #1 in overall customer satisfaction, comfort and durability
  • Sentinel Mouth Guard Co. offers a 1 year replacement warranty on this guard type in the event that you grind through your guard or it becomes defective
  • Must keep this appliance dry between uses, as layers can separate if soaked in overnight cleaning solution or left with water sitting in the teeth compartments

When deciding on an upper or lower guard, there may be some obvious factors that will dictate your decision.

For instance, if you’re missing teeth on either the upper or lower set, you will want to choose the set that has more. Or if you know you’re grinding your teeth, and you need to get a night guard quickly, but you have some upcoming dental work on your upper teeth that may change your dental anatomy, you will want to go with the lower teeth (or vice versa).

Same thing goes for loose teeth, or loose crowns/bridge work, etc- You will want to choose an opposing guard and avoid the potential to loosen that dental work with the continuous use of a tight fitting night guard.

Now, if you have all of your nice solid teeth on both the upper and lower side of your mouth and no plans for upcoming dental work, it really just comes down to preference.

The upper guard has been the “go to” choice for many but if you think a lower guard would feel more comfortable then go for it (unless your dentist has recommended a certain arch for a specific reason).

Many customers say that they prefer the lower mouth guard for grinding teeth over the upper as it tends to be smaller and less obtrusive.

NOTE: Tongue thrusters may be inclined to lift the edge of a lower night guard with the tongue (something to consider).

Are Night Guards BPA Free? Latex Free? What Are Night Guards Made Of?

custom night guard for teeth grinding

Most night guards are made from EVA material (Ethylene-vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate). The material is BPA free and latex free & is not considered hazardous or toxic by OSHA per 29 CFR 1910.

Ask your dentist or night guard lab to supply information regarding the materials used in the fabrication of your sleep device.

Sentinel Mouth Guards are made with ProForm materials.

All material used is BPA free and latex free & is not considered hazardous or toxic by OSHA per 29 CFR 1910.

“How do I clean my night guard?”

  • Daily care of your night guard is very important for sanitary reasons and to get the most life out of your guard.
  • The night guard should be cleaned with a soft toothbrush and a mild soap. It should be noted that some dentists recommend toothpaste as a cleaner. Keep in mind some toothpastes are too harsh and if not rinsed thoroughly can leave a white residue in the crevices of the guard. Dry the guard thoroughly and store in its breathable retainer case. Get in the routine of cleaning daily to prevent bacteria and discoloration.
  • For a deep clean, feel free to soak your night guard in a denture cleaning solution no more than 3 times per month and no more than the recommended time on packaging. This deep clean will keep the guard clear and like new.
Magnesium examples

Can Taking Magnesium Stop Teeth Grinding?

Can taking Magnesium daily stop my teeth grinding?

Yes and maybe and possibly not at all. So why do so many people recommend taking Magnesium to stop teeth grinding?

Many people all around the world have attested to the positive impact that a daily dose of magnesium has had on their teeth grinding habit.

Magnesium levels could be low (particularly amongst women).

These low levels of Magnesium can cause one to feel more anxious, muscle cramps and nausea. It can also affect muscle function and nerve function.

Not all people can or should take magnesium in a pill form.

Some individuals may need to “up” their daily dosage of magnesium the good old fashioned way, e.g. eating leafy greens, avocados, broccoli, beans, seeds and nuts, even dairy products, meat, chocolate and coffee!

What is Magnesium and how does it work?

Do you remember Magnesium (Mg) from the periodic table of elements in your chemistry class?

Magnesium is an abundant mineral found naturally in the earth.

One important function of Magnesium is to help the regulation of blood pressure. Magnesium is also needed for the successful contraction and relaxation of muscles and nerve function.

Magnesium supports a healthy immune system, helps keep bones strong and gives you more energy. It does all kinds of things. In fact, magnesium aids in over 600 bodily processes!

How much should I take?

Always check with your doctor before taking Magnesium. The recommended daily dose is 400-420mg per day for men, and 310-320mg per day for women.

What does Magnesium have to do with my teeth grinding?

Magnesium can help relax the muscles. Specifically, it can help relax the small, twitching muscles in the jaw, which reduces the pressure of grinding.

This new addition to your sleeping regimen should be implemented in conjunction with some other nightly practices.

Taking a bath with Epsom salts, meditation, soft yoga, massaging the neck, and making sure your bedroom is a comfortable place to relax and fall to sleep are all things that may make a big difference to your teeth and jaw come morning time.

Fact: Drinking alcohol before bed worsens teeth grinding. Avoid drinking or taking any stimulants hours before bed time.

Are most Americans Magnesium deficient?

According to World Health Organization statistics, most US adults are deficient in magnesium. Up to 75% of adults in the US do not meet the recommended amount of daily magnesium intake.

A damaged digestive tract and/or certain digestive disorders may cause individuals to not be able to absorb Magnesium fully or properly.

Can I take too much Magnesium?

Absolutely! Taking too much Magnesium can lead to confusion, feeling sleepy (lethargy), muscle weakness and stomach pain/diarrhea.

What other home remedies are there to stop teeth grinding?

Some studies claim that B-complex vitamins have a significant effect on controlling teeth grinding. Deficiencies in B Vitamins have also been linked to severe psychological stress, depression and panic attacks.

Taking a B Vitamin supplement in addition to the Magnesium may help curb the intensity of teeth grinding and/or stop it all together.

Wearing a night guard will not stop the teeth grinding habit, but will protect the teeth from the physical harm that is caused from the habit.

In addition, the night guard will help relieve tooth aches and pain in the muscles and joints that stem from the grinding action.

Make good decisions. Lessen or cut out the things that you know may be harming you. This includes sugar, alcohol, caffeine, drug stimulants like Adderall, cigarettes, and negative situations that are causing you stress.

Are there any potential side effects of taking Magnesium?

Most common side effects from taking Magnesium reported are upset tummies, nausea, vomiting and diarrhea. Basically, all the tummy woes can occur.

This doesn’t tend to happen if you’re getting your Magnesium intake naturally (through foods). Magnesium supplements seem to be the culprit in this case more often than not.

Is teeth grinding caused by a mineral deficiency?

It could be that teeth grinding is caused by not just one factor, but many.

A mineral deficiency may be part of the equation. Another big part of the picture is stress. Researchers are still working to find the exact cause of teeth grinding and how to stop it.

What happens if I wear my teeth down?

Your teeth can start to feel like they’re “sprained” all the time. You may be able to press on certain teeth with your fingers and feel pain. The wearing down of your teeth can cause tooth sensitivity, jaw pain, tooth pain, broken teeth, and even not being able to open and close your mouth properly.

Can you cure teeth grinding?

can you cure your teeth grinding?

There is no surefire way to cure teeth grinding, but there are ways to lessen the intensity of teeth grinding. Sometimes we simply stop on our own with no real explanation.

Children oftentimes grind their teeth together intensely while they’re young, and outgrow the habit at a later age.

Adults can also go through spurts of teeth grinding throughout our lives only to stop and then start again. Some of us grind severely our whole lives.

Stress is still the #1 indicator of teeth grinding. We hold an incredible amount of tension in our jaw area. Be aware of this and take on the practice of stretching, relaxing the neck, face and shoulder area. Relax the mind and wear a dental night guard.
