Product Reviews

  • B. Werger

    Thank goodness we can take more that one dental impression because this is not my thing. 😂 After ruining the first two trays, I finally figured out what I needed to do to the 3rd one. I mixed it a lot faster the 3rd time around and it finally worked out for me. After I finally figured it out, I mailed it into the company. Got my night guard back about a week or so after I sent off my impression. I couldn’t believe that there is a product on the market to make a custom mouth guard. After I got my braces off, I think my mouth guard was around $400. This was way less expensive and looks really similar. I’m happy with the end result!

  • Brandy Reagan

    These worked great! I needed the heavy duty as I have been a teeth grinder for many years. Took an impression of both my top and bottom teeth but it’s only to make sure the bite is correct. I’m so grateful because I have a bad overbite, but they still fit over my teeth perfectly!

    The guard stays in place while I’m sleeping! I’ve had a bad run with mouth guards in the past so I’ve been going off and on without protection for way too long. This is a lifesaver! I’m so happy it fits.

  • Jae Jyoo Wang

    Can’t believe I’m writing a product review for a mouth guard but it’s that good.

    This is the most comfortable mouth guard I’ve ever worn. I’m impressed by this brand. Responsive, quick and high quality!

  • Leah Delaney

    After my dentist told me I needed a guard to prevent teeth grinding, he tried to sell me one of his night guards. When that didn’t work because of the astronomical cost of the guard he wanted to sell me, I was then referred to an ENT doctor. I was told to stress less, take magnesium and wear a night guard. I was about to give up when I did a search and selected this company because of the positive reviews. I’m adding another positive review.

    So far, I have had only positive things to say about this experience.

    For this night guard you will need to take upper and lower dental impressions.
    I received the kit quickly and read the instructions thoroughly but I still had a few questions and called the company and customer service was great. My questions were answered.

    I was apprehensive about making the mold. I tried placing the mold tray in my mouth and gagged. The company representative (Suzanne?) told me to use the slightly larger tray because I should not hit the tray with my teeth. They include two tray sizes but an additional size is available should the included ones not fit properly. It’s also important to mix the molding clay properly into a consistent color before inserting into the tray.

    Set a timer for 3 minutes. You need a full 3 minutes with the molding clay/tray in your mouth for the mold to form properly. Try doing this in front of the mirror. If you fail you can call the company and they will supply you another kit at no cost.

    After you make the mold you need to send a photo to sentinelmouthguards@gmail.com and they will confirm whether it is successful before you mail it to the lab in a self-addressed, prepaid envelope.

    It took about 10 days from the date of mailing for the guard to arrive.

    The guard comes with a free retainer case.

    My guard required no additional adjustments but the company will help you should you need it.

    This was my first guard and has worked successfully so far. According to the company, the guard should last about 2 years. They also keep the impressions on file for 1 year from the date of purchase in case you need to reorder.

    I researched a lot of other companies and they didn’t require the upper and lower teeth impressions. I like that they make sure the bite is correct. I was skeptical because it’s so much cheaper than the dentist but I got my guard and waited to weigh in. The guard fits perfect and I’ve been sleeping soundly for several weeks now. This is the real deal. Thank you for existing Sentinel. You’re a tooth saver!

  • Jordan Harris

    I have gnawed through several of this online guards from different companies. I was about to pay $1200 at my dentist for a thicker one when I found the Sentinel team and decided to give them a try. The first impressions I thought were okay but they sent new impressions explaining that they needed a really nice impression to make a proper fitting guard. I retook the impressions. They didn’t charge me for the redos. I got the guard back and it fit perfect. So far so good!

  • Sarah34

    I absolutely love it!
    My mouth feels so much relief and the customer service is spectacular. It is so much better than another company that I had tried previously. The fit is perfect for my mouth and I feel comfortable wearing it.

  • Mason Berger

    Been wearing mine for a few weeks and it’s been a life changer. My headaches and jaw soreness are gone! I’ve had many night guards through the dentist. I’ve paid a lot of money for these things. It’s nice to find an affordable option that still has the high quality I need. Thank you!

  • Jaycin Diaz

    MIX FAST! I mixed my putty too slow and the putty hardened before I was ready. I contacted the sentinel team and they sent me new putty. 2nd time around went much better but mix quickly because the putty will harden and you will not be able to get your teeth into it! End product fit great. I’ve been wearing it nightly and have seen a significant reduction in my jaw pain and morning headaches.

  • Nicholas Cook

    So glad they started offering the 3mm night guard. I grind so badly that my teeth were wearing through the 2mm hard guard. I’ve had this one for 8 months now and so far so good!

  • Shana Odlen

    Spoke with Alexandra and she was very helpful and recommend that a ask for some extra putty!!
