Dental night guards for teeth are also known as mouth guards, dental guards, or nocturnal bite plates. They function by creating a barrier between your teeth and preventing them from touching each other. These night guards help to relieve tension and they cushion the muscles in your jaw when you clench it.

These are the current available DenTek night guard models:

We'll go through each of them in detail in this DenTek Night Guard review.

DenTek Dental Guard “Professional Fit“ Review

The transparent DenTek Night Guard Professional model is made for use on the upper teeth. This is a dual-layer mouth guard. The inside layer is made of soft material for comfort and a good fit. The material of the outer layer is hard and durable. This adds to the product's safety and increases its lifespan.

Watch this video to learn how the product works:

Fit: ★★★☆ (3/5 stars)

It's fairly simple to mold it to fit your teeth. Just follow the instructions. However, it won't be a perfect fit like a custom night guard from a dentist's lab.

Effectiveness: ★★★★☆ (4/5 stars)

When evaluating DenTek Night Guard reviews on Amazon, you’ll find many happy customers reporting that they stopped grinding and clenching at night. Some customers say it also stopped them from biting their lips, cheeks, or tongue while sleeping.

Durability: ★★★★☆ (4/5 stars)

You’ll find a wide range of DenTek Night Guard reviews mentioning the product's lifespan. Some say they were chewed through within 12 days, while others claim they lasted for more than 6 months.

Comfort: ★★☆ (2/5 stars)

Its inner layer is made from a comfortable, soft material. However, if you are searching for DenTek Night Guard reviews for the “Professional” version on Amazon, you’ll find many customers reporting that the mouth guard feels large and bulky and that it’s difficult to close their mouths.

Save your money and save your jaw, teeth, and throat! Because this product forces my mouth to remain open, my throat got extremely dry throughout the night.

DenTek Comfort-Fit review

The DenTek Comfort-Fit night guard model is a lower-jaw-fitting, ready-to-wear dental guard that requires no molding or boiling. This is a one-size-fits-all, as it can be adjusted, and it has a retention band that keeps it in place as you sleep.

It also contains a wear indicator, so you can see when it's time to throw it away and replace it. When comparing dental night guard costs, this is the most affordable model of the DenTek dental mouth guards.

Here’s a video provided by DenTek that explains how the “Comfort-Fit” model works:

Fit: ★★★☆ (3/5 stars)

This is a one-size-fits-all model. The size can be adjusted through the band. Many customers are satisfied with the Comfort-Fit model, reporting in their DenTek Mouth Guard reviews that it’s comfortable to wear. However, there are also some saying that the Dentek Comfort-Fit night guards are just not tight enough and don’t stay in place.

These however only stay in place as long as you're closing your teeth on them. As soon as you relax your jaw or open your mouth, all bets are off. Additionally, my tongue will naturally bump the guards, moving them out of place if my teeth aren't clenched, and as they start shifting around, they make me gag. I can't even make it from the bathroom to my bed with these in before I have to take them out, which is its own ridiculous drool adventure.

Review by gene soda

Effectiveness: ★★★☆ (3/5 stars)

Not all customers seem to be happy with the effectiveness of the DenTek Comfort-Fit since many people report that it doesn’t stay in place and slides around the mouth.

Comfort: ★★★★☆☆ (4/5 stars)

With its slim-fit design, it’s not bulky to wear like the other DenTek Dental Night Guards. It’s also easier to breathe with them than with bulky full mouth guards.

Durability: ★★★☆ (3/5 stars)

Most customers report in their DenTek Comfort-Fit Night Guard reviews that it lasts up to four months.

DenTek Ultimate Night Guard Review

The DenTek Ultimate Night Guard includes a SmartFit Tray to provide a better fit than a full mouth guard, and it also has a flex band like the DenTek Custom-Fit model.

With this model, DenTek might have tried to combine the best of both types. It provides a more secure fit like DenTek's “Professional” Night Guard and a slim design like the “Custom-Fit”.

Watch this video to find out how the DenTek “Ultimate” Night Guard works:

While in theory, it sounds like a good idea, the DenTek Night Guard reviews for the “Ultimate” edition are mixed:

Fit: ★★★☆ (3/5 stars)

According to the DenTek “Ultimate” Night Guard reviews that you find online, many customers are having problems getting the correct molds with this version. People claim that it pops out during the night, and it can be a potential choking hazard. Follow the instructions carefully when making the mold, and keep the water boiling during the process.

Effectiveness: ★★★☆ (3/5 stars)

Some customers say it fixed their grinding problems, while others say the DenTek Night Guard keeps popping out in the middle of the night.

Comfort: ★★★★☆☆ (4/5 stars)

Since the DenTek Ultimate Night Guard is not as bulky, customers find it rather comfortable to wear. It’s also not noticeable to other people around you.

Durability: ★★★☆ (3/5 stars)

Customers of the DenTek Night Guard are reporting that theirs lasted around 6 months. It probably depends on how much you grind your teeth.

DenTek Ready-Fit Dental Guards review

DenTek Ready-Fit disposable night guards are individually packaged, ready-to-wear dental guards that are suitable for travel. No boiling and no molding are required with these.

This product is different from the other night guards offered by DenTek. The mouth guard has flexible pillow tubes that gently cushion your teeth during grinding, while the retention wall keeps the guard in place.

Fit: ★★★☆ (3/5 stars)

DenTek “Ready-Fit” disposable dental night guards

Since this is a one-size-fits-all product, you’ll find quite a few reviews saying that it has a bad fit.

Effectiveness: ★★★☆ (3/5 stars)

These DenTek Night Guards are fairly successful in halting the grind, and many customers are happy with the result.

Comfort: ★★☆ (2/5 stars)

You’ll find Dentek Night Guard reviews for this model in which customers complain that the plastic is too hard (not soft silicone) and causes discomfort.

Durability – ★★★☆ (3/5 stars)

Even though this is a disposable product, customers are reporting that it is very durable and lasts a long time.

DenTek Night Guard instructions

It’s vital that you follow the DenTek Night Guard instructions to ensure the best fit for your mouthguard.

When looking for Dentek Night Guard reviews online, you'll find plenty of complaints regarding improper fit. In some cases, this may be because the product is problematic, but in other cases, it could be that the customer didn't carefully follow DenTek's instructions.

DenTek has a helpful video that explains the molding process in detail:

Overall, DenTek makes great dental night guards for an affordable price.

However, since they are not made in a dentist's lab, the effectiveness and comfort of these night guards may be limited depending on your needs.

If you are a chronic and forceful teeth grinder, then you may want to consider a custom-made guard. These will last longer, fit better, and ensure that you don't grind your teeth, or damage your teeth when you clench your jaw.

While there are a variety of companies that offer the convenience of custom-made, dentist-quality nightguards that you can order online, we recommend the Smile Brilliant Night Guards.

They receive stellar reviews based on comfort, fit, durability and effectiveness, and they come in various strengths and purchase options so you can find the one that works best for you.

What's more, Smile Brilliant will keep your dental impressions so that when you need to purchase another guard in the future, you can order one without retaking your impressions.

In the table below, we compare Dentek and Smile Brilliant night guards:

DenTek night guards vs. Smile Brilliant night guards

DenTek Night Guards

SmileBrilliant Night Guards

  • Cheap price

  • They may wear out quickly if you are a heavy grinder.

  • Might be uncomfortable to wear

  • They can fall off during sleep if they don’t fit perfectly (choking hazard!)

  • Some of the DenTek Night Guards have sharp edges and might rub or cut the gums.

  • They may not have a perfect fit like a custom night guard from a dental lab.

  • It requires you to follow the product instructions to the T, or the product will not work.

  • Quality product

  • Comfortable fit

  • Lasts up to 1 year

  • Hand-crafted by dental lab technicians

  • Travel case included

  • 45-day trial

  • 100% money-back guarantee



To summarize our DenTek Night Guard review, these mouth guards have a variety of quality features, and are a good solution for many people, especially if you aren't a severe tooth grinder, or you'd like to try a night guard to see if it's something you should be adding to your nighttime routine.

Keep in mind that ready-to-wear night guards have some limitations and may not fit as well as ones that are made in a dentist's lab. A night guard that doesn't fit perfectly might fall out during the night, or cause discomfort.

The Smile Brilliant Night Guards are more expensive, but you will receive a product that fits your specific needs and feels comfortable in your mouth.
