Best Night Guards

The night guards we review are easily accessible, as they can be ordered online, they’re also affordable and almost all custom fit. 

 

1. Remi - Best Overall

When it comes to at-home night guards, Remi takes the top place, being BPA-free and comfortable, made from 1mm-thick dental-grade plastic. 1.3mm and 2mm options are also available. 

Signing up for the Remi Club provides you with a new night guard every six months for $49 each, as they inevitably accumulate bacteria and plaque. Overall, Remi is estimated to be 80% cheaper than prescription mouth guards. There is also a 30-day money-back guarantee. 

Bottom Line: 

Remi is a high-quality mail-in mouth guard that covers all your needs, from a custom fit to replacements when needed.

Pros

  • Custom mouthguard without needing to visit a dentist
  • Prepaid shipping for completed impressions
  • Subscription option provides a new mouth guard for $49 every six months
  • Teeth whitening products included with some subscriptions.

Cons

  • Each replacement night guard costs $49, making it the most expensive in terms of ordering a new guard.

2. SmileBrilliant - Best For Severe Grinding

The Smile Brilliant night guard is made for heavy teeth grinding. At 2mm thick, they are made to protect your teeth for three months each.

The packages for Smile Brilliant night guards accommodate the needs of heavy teeth grinders by providing more frequent replacements. There are packages of one, two, and four guards, all with free shipping and a free impression kit. 

Higher-end packages also include affordable replacement guards, at $25 each compared to $40. With worldwide shipping available, the Deluxe package of an initial four-guard set is the most cost- and time-effective option. 

Bottom Line: 

The Smile Brilliant night guard comes with cost-effective lifetime services to manage heavy nighttime teeth grinding.

Pros

  • Thicker 2mm mouth guards to endure heavy grinding
  • Lifetime reordering options available
  • Three package choices
  • Latex and BPA-free mouth guards
  • Worldwide shipping

Cons

3. Meyarn - Most Comfortable

Meyarn is a “baby standard,” comfortable night guard that can conform to the shape of your dental arches. Reviewers describe it as effective even with dentures. 

The brand is also one of the cheapest options, at less than $20, which is likely due to its standardization. Despite the soft material, it may not be a comfortable fit due to the one-size-fits-all approach. 

Bottom Line: 

Meyarn mouth guards are soft and comfortable, making them suitable for those with sensitive teeth and jaws, as long as they fit the size of your dental arch.

Pros

  • Soft plastic that doesn’t require shaping
  • Designed according to oral anatomy, in order to fit different dental arch shapes
  • Ships worldwide

Cons

  • One size fits all mouth guard, not custom-made

4. Cheeky - Best Customized

The Cheeky mouth guard is perhaps the best custom-fitted night guard you can purchase online, made from molds using an impression kit. 

You can also choose the thickness and whether the mouth guards are soft or hybrid. Hybrid mouth guards are soft on the inside but made from durable acrylic on the outside. You are not charged more for thicker guards.

If you still aren’t sure whether Cheeky is right for you, a one-time purchase option of $129 is available. This can be converted to a subscription later. Cheeky guards are also covered by FSA and HSA insurance. 

Bottom Line: 

With a customized fit and the ability to choose between a soft and hybrid night guard, as well as its thickness and subscription type, Cheeky is the best personalized mail-order mouth guard.

Pros

  • Customized night guard with instructional video online
  • Replacements are sent every three months
  • Both soft and hard/soft hybrid options are available
  • Accepts FSA and HSA insurance

Cons

  • Quarterly subscription option costs $49 every three months for a replacement night guard

5. Sentinel - Most Durable

The Sentinel mouth guard is suitable for both day and night use. With up to 3mm of hard plastic, even the heaviest of teeth grinders can find protection and relief from tooth damage and jaw pain. 

Night guards by Sentinel also last much longer than other products reviewed here, with a life expectancy ranging from two to five years with correct cleaning (after every use). 

However, if you are looking for a soft night guard, Sentinel is not right for you. Only hard options are available, which contributes to its longevity. 

Bottom Line: 

Sentinel offers some of the most durable night guards. Even if you are a heavy grinder, it may last several years with correct care.  

Pros

  • 1mm, 2mm and 3mm thickness options
  • Guards to protect against tongue and cheek biting are available
  • Custom athletic fits available for contact sports

Cons

  • Customers can only purchase a hard night guard

6. Teethnightguard.com - Best For Sensitive Teeth

Teethnightguard are handcrafted by dental technicians, giving them the extra edge when it comes to protecting sensitive teeth. With the additional Front Cut, where you can choose a lower trim for the front four teeth, your lips are able to rest on your teeth in a more natural position. 

Environmental sustainability is also an advantage, with the average lifespan of a guard being two to three years. They can last up to five years, but during this time your impressions will be kept on file to ensure a speedy replacement if needed. 

Bottom Line: 

The handcrafted manufacturing process of Teethnightguard, and their Front Cut option, make it the best choice for sensitive teeth.

Pros

  • Hand-crafted, custom fit
  • Can be made compatible with missing teeth
  • Free from BPA, latex and phthalates
  • Available in up to 4mm of thickness

Cons

  • Five-year Storage & Savings Plan can only be purchased within four months of ordering

7. Sporting Smiles - Best Value

Sporting Smiles mainly focuses on mouth guard products for sports, but there are dental options too. All of them are designed for heavy teeth grinders, such as the Flexible Hard models. There is a soft grinding guard for teeth grinders who also clench, and barely visible models too. 

The brand is up to half the price of other custom-fitted night guards, with models costing between $90 and $105. The flow chart on their website illustrates the best options for grinding, clenching and severity. However, your molds are only kept for one year, so you would have to repeat the impression kit again. 

Bottom Line: 

Sporting Smiles are affordable mouth guards designed for a range of preferences, at up to half the price of other customizable brands. 

Pros

  • Prices start at $90 per guard
  • Less noticeable back cut options
  • Hard and soft choices

Cons

  • Molds are only on file for one year

 

What Is a Night Guard and How Does It Work?

A dental night guard looks similar to an aligner but is designed to create a barrier between the upper and lower teeth. This both reduces teeth grinding and provides your teeth and jaw with protection against the damage grinding causes. Left unaddressed, severe teeth grinding can eventually break or wear down your teeth. 

You may find that wearing a night guard helps to retrain the muscles in your jaw. The muscles’ neuromuscular reflexes respond to the improved jaw alignment, and can eventually return to a more normal pattern [1]

 

Types of Dental Night Guards 

There are several types of dental night guards that vary in how well they are individualized to your mouth:

  1. Over-the-counter
  2. One size fits all
  3. Boil and bite
  4. Mail-in custom fit
  5. Custom-fit by a dentist

 

Over the Counter

Over-the-counter night guards can be one size fits all or boil and bite. They are not designed to specifically fit your mouth, and their materials may not accommodate your teeth sensitivity or any other needs you have. 

 

One Size Fits All

One size fits all guards are made based on average sizes, and are less likely to fit you as a result. They do not account for chipped teeth, missing teeth or other issues. 

 

Boil and Bite

Boil and Bite night guards have semi-customizable fits. They require you to soften them by boiling them for 30-60 seconds (or according to instructions), you will then bite into them to create a shape that fits your teeth and dental arch. These can be bulky and unstable, even if a relatively good fit is achieved. 

 

Mail-in Custom Fit

Most of the night guards we review here are mail-in custom fits. These cut out the time and expense of dental appointments, and instead involve creating molds with a home impression kit. The one downside is that you do not have in-person support

 

Custom Fit By a Dentist

A mouth guard custom fit by your dentist is an excellent option, as they can assess whether a night guard is right for you, and what your needs are in terms of thickness and hours of use. They can also identify and treat other issues such as damaged teeth from long-term grinding or cavities. 

 

What to Look For When Choosing a Night Guard

With a range of options on the market, here’s what to look for when choosing a custom night guard. 

 

Quality of Material

You want a durable, comfortable and non-toxic material when purchasing a night guard. It is best to avoid as many risky chemicals as possible, including phthalates, which are linked to higher all-cause mortality [2]

 

Ensure your choice of nightguard is phthalate-free as these chemicals are STRONGLY associated with lung, kidney, liver, and reproductive system damage.

 

Personal Comfort

If you’re not comfortable, you’re unlikely to wear your night guard. You may also find that your teeth grinding gets worse or changes its movement pattern, or any jaw pain, mouth irritation, tooth sensitivity, sleep disorder or misalignment worsens. 

 

Style

Some night guards are made for upper teeth only, or you may have a lower guard, or both. Other guards mostly cover your back teeth, and are made for daytime use as you cannot see them. 

 

Durability

Some of the night guards covered here last only three to six months before needing a replacement, while others last up to five years. Although shorter-lasting guards are often replaced at a fraction of the initial cost, greater durability is kinder to the environment and your wallet. 

 

Price

Your first set of custom-fitted night guards generally starts at $90 each, such as the grinding guards from Sporting Smiles. However, it’s also best to look at their lifespan and the cost of replacements: how much are you likely to pay per year, or five years? 

 

Are Night Guards Bad for Your Teeth?

A well-fit night guard should protect your teeth from the damage caused by teeth grinding. However, there are case studies where night guard use has led to issues such as anterior open bite, as they did not fit correctly [3]

 

Advantages and Disadvantages of Night Guards

Night guards’ main advantage is they help prevent tooth enamel loss, and the appearance of broken or fractured teeth. They may also relieve jaw and mouth pain as well as stiffness, and do not have the potential negative effects of Botox. 

 

On the other hand, a night guard is not a cure for teeth grinding. Poor stress management, excessive caffeine or tobacco use, can contribute to bruxism too [4]

 

When Should You Talk to Your Dentist About Dental Night Guards?

You should talk to your dentist about a custom night guard if you notice teeth grinding and clenching habits [4]. If you already have broken teeth, it’s not too late to prevent more harm. Jaw or ear pain and headaches may call for a night guard too.
