DenTek ® Dental Guard – Full Review

  • Dealer: Amazon




DenTek is a development lab that focuses on the health of your mouth and provides three different nighttime mouth guards that prevent damage done by grinding and clenching. The guards are adjustable to fit your mouth and require little-to-no boiling depending on the model you select.

The company’s Professional Division partners it with health care professionals and experts to help develop products that work and educational materials that make it easy to properly use its line of mouth guards.

DenTek products have an average and mostly positive rating across most major review sites and are well-received enough to find a home in many major retailers across the U.S. They tend to not be bulky, but some users report the size is an issue because they are too small to stay in the mouth or too thin and don’t last quite long enough. With the low cost, however, the price seems to be right for most.



Product Features

DenTek has recently expanded its mouth guard option from two devices to three. The company now offers the: Comfort-Fit Dental Guard, Custom Comfort Dental Guard, and Maximum Protection Dental Guard. The products differ slightly on their molding instructions, so be sure to read directions carefully if you switch between two models.

Choose the right dental guard for your needs based on your comfort level with having guards in your mouth as you sleep and your level of bruxism.


1. Comfort-Fit Dental Guard

This guard is designed to fit on your lower jaw and provide protection against light teeth grinding. It has a wear indicator that will let you know when it is time to replace the guard. Users have reported that it can be molded to the top teeth as well, with some finding this to be easier but noting that the wear indicator is less effective this way.

The guard relies on a retention band to help it stay in place but users still report that it has a tendency to fall out if the molding and shaping to fit their mouth wasn’t done quite right.




To test-fit the guard, rinse it in warm water. Then put your lower teeth on it and bite down.

Adjust it until the back bitepad covers at least half of your back molar, but make sure it does not extend beyond your molar. The molar pads have five notches that allow you to adjust them farther back. Make sure it can reach your back teeth without you having to pinch or bend the front because this can damage it.

The company says each guard should last at least six months, though some users report that it can last as little as three weeks.




2. Custom Comfort Dental Guard

This model is also a transparent guard designed for the lower jaw. This iteration is slightly thicker and uses two layers of materials: a soft inner layer for teeth comfort and a sturdy exterior layer that provides grinding and clenching protection. It’s designed for moderate bruxism and clenching.

This produce has very mixed reviews, though more recent purchasers tend to be more satisfied. The device offers a decent mix of comfort and protection, but they only last around two months – averaged from users’ reviews. Long-time users report that the custom guards are different than they used to be, offering a slimmer fit with a narrower tooth bed. This is good for smaller mouths but means it does not fit larger ones as well.

This is a boil guard and the company recommends you use a microwave to start the boiling process.  First gather up your materials. You’ll need a:

  • microwave
  • ceramic cup
  • metal fork
  • dental guard
  • clock with a second hand (or a timer)
  • ceramic plate
  • mirror

To fit your guard, follow these instructions:

  1. Fill your cup with water and heat it in the microwave until the water is boiling.
  2. Remove the cup from the microwave once the water boils; let it rest for 15 seconds.
  3. Place the guard in the hot water and make sure the softer side is facing down. Hold it there for 50 seconds.
  4. Remove it with the metal fork and place it on the plate with the soft side up. Let it sit for about 10 seconds.
  5. Put the guard in your mouth but do not bite down. Use the mirror to align it between your two front teeth.
  6. Bite down firmly and suck to remove the moisture from your guard. Use your tongue and fingers to press the material around your teeth and gums.
  7. Firmly bite down again and leave the guard in your mouth for between 3 and 4 minutes.

The dental guard can be remolded once.


3. Maximum Protection Dental Guard

Perhaps the best-received DenTek guard is its Maximum Protection Dental Guard, which is for light to moderate grinding. Customers find it easy to mold and use, without causing much pain or soreness. They tend to last between one and three months.

This guard is only for the upper teeth and is a traditional boil-and-bite design. The guard uses two layers and features an ergonomic design to fit your teeth comfortably while providing a stronger shield for grinding protection. The bottom layer is made from EMA and will provide a slightly longer use-time compared to the company’s other models.


The softness of the inner lining has also helped to reduce noise from grinding, according to many users.

This guard comes with a forming tray so you’ll need to put the guard in this first and ensure it’s in the right place. Test it by putting the guard in and biting down. Move your teeth so that the guard is centered and make sure that it covers through the middle of your back molar.






To finish the process, you’ll need to mold your guard by:

  1. Bring a pot of water to a boil.
  2. Remove the water from its heat source and let it rest for 10 seconds.
  3. Place the dental guard (loaded in the tray) in the water for 60 seconds. The tray should be face down.
  4. Remove the guard from the water and dip it into room temperature water for no more than 1 second.
  5. Place the guard in your mouth and center it on your front teeth.
  6. Firmly bite down and hold for 2 minutes.
  7. Remove the guard and rinse it under cool water for 20 seconds.
  8. Remove the guard from the tray and it will be ready to use.

To clean your guard, brush it with toothpaste or rinse it with mouthwash after each use. Don’t use very hot water because this can cause it to lose some of its molded shape.



Common Questions

  • Does it reduce grinding noise?

Many users report that it can reduce grinding noise as well as some snoring. This is typically for severe cases of either and may not completely stop noise associated with grinding or snoring.


  • Why does mine look a little different from the website picture?

Models come in different colors, so you may not get the exact item pictured online. Some resellers use model pictures that include a case, but not DenTek sells guards with and without the case; be sure to read the product description to see if a case is included with your purchase. Consumers say DenTek is quick to remedy any situation where the wrong product was shipped.


  • Can this fit a smaller mouth?

Users have found they can adjust the Custom Comfort and Maximum Protection models by cutting the back. If you do this, be sure to round off any edges to avoid hurting your mouth.


  • Who can use it?

These products are designed for adults. Like all mouth guards, consult with a dentist before having someone under the age of 18 use it during the night.



Very cheap compared to dentist office models.
One year money-back guarantee.
Adjustable and low profile to fit without getting in the way.
Users say the fit is great for most mouths.
Guards tend to be both soft and comfortable




Not all models fit well in people’s mouths.
Smaller models can irritate the mouth by moving around and causing a gag reflex.
Most models are not durable and tend to wear out in under a month.
Some of the dual-layer guards have split or the softer side has been chewed through quickly.

 For crooked teeth, some users have complained that the guard shifted teeth and caused pain after use.



About the Maker

DenTek is a product development company lab that has a presence online and in many major retailers. The company focuses on oral care for kids and adults. It has high rankings from protection and healthcare groups as well as from users of its products. It offers a series of educational packets to help users understand both these guards and general health issues.



Final Recommendation

If you need an inexpensive guard and don’t mind replacing it after a month or two, this is a good option. It will also help users with very light grinding or clenching. Guards tend be a little on the small side and may be tight in your mouth, which can cause an issue with irritation. It’s a decent purchase and worth trying out since the cost is so low.
