Teeth grinding is a serious unconscious habit that can reap enormous havoc on your life. Not only can it permanently ruin the enamel on your teeth, but it can also cause problems with you bite, pain in your jaw, result in chronic headaches, and keep you from getting the sound rest you need.

The Sentinel Custom Night Guard offers a person a dental-quality alternative to paying a fortune for a custom-dental guard from a professional dentist. It still provides the same benefits as one you could purchase at your dentist, it is still custom fit and allegedly very effective for helping such ailments as TMJ, Bruxism, and heavy breathing.


Sentinel Night Guards- Product Features

Each individual Sentinel Night Guard offers a custom mouthpiece available for a man or woman- and for either the top of bottom teeth. All of these night guards are made to be hypoallergenic, BPA free, and are FDA approved for safe use.


The Sentinel Night Guards for teeth-grinding are offered in 3 models to accommodate your individual mouth guard needs and preferences:



  1. Sentinel Soft, Clear, Night Guard (0.40, 0.80, .120) (Soft inside/Soft outside)
  2. Sentinel Dual Laminated Night Guard Hybrid (2mm thick) (Hard Outside/ Soft Inside)
  3. Sentinel Hard Acrylic Night Guard (0.40 or 0.80) (Hard Inside & Out)


1. Sentinel Soft, Clear Night Guard ($98.50)

The Sentinel Soft model is very much like the ones that professional dentist’s offices design. The Sentinel Soft Clear Night Guard is ultra-soft inside and out for those who prefer the luxury of having an extra comfortable experience. It is recommended for individuals who have never yet worn a night guard and features 3 options of thickness (.40, .80, .120)


Although the Soft versions of night guards used to be the most popular preferred, now dentists are stating that wearing a very soft night guard could actually make you grind your teeth more. But do not let that discourage you as this particular model has received many positive reviews. The Sentinel is covered with a 6 month warranty.



2. Sentinel Dual Laminated Night Guard Hybrid ($138.50)

The Sentinel Dual Laminated Night Guard Hybrid is one of the most cutting edge designs that is available without getting a dentist involved. Although it is fairly new, it is quickly becoming one of Sentinel’s most popular night guard models. It is recommended for individuals who moderately grind their teeth at night (bruxism.) It features a very soft inside for comfort, and a hard outside and is 2 mm thick (no options like the Soft, Clear Guard and the Hard Acrylic Guard.)


This is a great night guard for those who want comfort, but the best protection possible. The Sentinel includes a 24 month warranty.




3. Sentinel Hard Acrylic Night Guard ($144.50)

The Sentinel Hard Acrylic Night Guard is the hardest of the Sentinel models. It is recommended for the strongest protection for those who experience severe teeth grinding, because it holds the teeth in place very firmly. It is offered in two thicknesses (0.40 and 0.80) and boasts a life-span of 2-5 years.


The Sentinal Hard Acrylic Night Guard is best used by individuals who consistently wear night guards on a regular basis. It secures the jaw, preserves placement of the teeth, and will work ideally for people who are concerned about their teeth shifting. Because of its hardness- it is the most durable of all of the Night Guards manufactured by the Sentinel Company. The Hard Acrylic Night Guard comes with a 2 Year (24 month) warranty.





How to Choose the Right Model???


When choosing between the three different models of night guards that the Sentinel Co makes you may have to consider how severely you grind your teeth, what the comfort factor means to you, whether you are concerned about your teeth shifting, and which fit soft/hard you just prefer better.


NOTE: You may be confused at which option to choose in a night guard top or bottom/upper or lower. When considering which option remember that usually the upper is the most popular. Although you will want to account for if you have more broken teeth on one place than another, if you need to protect the teeth you still have, or whether you have dental work that needs to be done that can be compromised by selecting the wrong option.

    I just rec’d my Sentinel Mouth Guard and I was extremely disappointed by the the flimsy, poor poor quality of the materials used. If it lasts a week, I will be surprised. If I ever write a book on “How Th Waste $100,” Sentinel’s Mouth Guard will be on page one.
