Customer ratings & reviews

I have TMJ and absolutely have to sleep with a nightguard. My dog chewed mine from the dentist and I desperately needed an affordable replacement. This did the trick! Very happy with the product and excellent customer service!!!

This guard is the best I've ever worn. I'm missing all of my right side molars & still a superb fit. Hands down! The best! , Mary B.

Thank you! Sentinel mouth guards has made a huge difference for me. For years dentists would talk to me about my teeth grinding and then want to charge me $600-800. I was always concerned with the fit and whether I'd take it out in my sleep. I had one over a decade ago and it didn't stay put over night. When I heard about Sentinel and saw the savings of going through you direct, I knew I had nothing to lose. The value has well exceeded the cost. The fit, comfort, & protection have made a difference in protecting my teeth. Thank you. Now my only question is in the next one I order will I try the all hard/soft or stick with the dual laminate.

I have tried those boil-it-yourself mouth guards and they never make it through the night. They always end up on my nightstand. I gave Sentinel a shot. I was probably their worst nightmare of a customer. I had a ton of questions and low expectations. I got the kit to make a mold quickly, followed the instructions, sent in my pictures of my impression to Sentinel. After approval, I sent the mold to their lab using the shipping package they sent me. Sentinel took about 7 days to make my guard. I received it and immediately LOVED it. The guard is not bulky at all. It is very thin and comfortable to wear. I highly recommend this guard!

Great service which has saved us a lot of time. Very quick and good communication throughout. Thank you.

Great customer service. Excellent product! Chose the hard dental guard at first and switched to this dual laminated type because the hard felt a little too tight on my teeth. The soft inside lining of the dual makes the night guard very comfortable to wear. Only night guard I've ever been able to sleep with comfortably. Thanks for working with me Sentinel team.

Saw that this site was mentioned on Reddit as a good place to get a night guard so I decided to give it a try. Very, very, glad I did! Saved me 500 bucks! I've sent some friends this way too and they were all happy as well. Thanks a ton!

I ordered a dual laminate nightguard. The kit came quickly and following the steps was clear and easy. Even with Covid19 shutting things down I received my guard in good time and it fit like a glove. Unfortunately I had bigger issues that appeared with my jaw. I emailed my problems and Alexandra replied promptly but my problem requires a more complex solution that has to be done in person with a dentist. Sentinel refunded my entire purchase price just as they guaranteed when I mailed the guard back. I would definately use their company again if my family needs other products!

Finding the perfect nightguard can be a lot like the Goldilocks story. As a nightguard user, I have gone through many and it really does come down to personal preference and the ability to have a custom made nightguard for such an affordable price is a blessing!

Researched a few companies online before settling on Sentinel. My main grievance with the other night guard labs was that none of them answered the phone. Some didn't even have numbers to call (just emails) and they were slow to respond. Sentinel was prompt and happy to answer my million questions. They made me an exceptional comfortable and STURDY dental guard. Happy customer here! Thanks a ton!
