Customer ratings & reviews

EXCELLENT QUALITY, GREAT FUNCTIONALITY!! I chose this company because I can customize the thickness. I only wear this for weightlifting so I didn't want a bulky mouth guard..very happy with purchase.

Beautifully crafted and it does the job!! This guard is awesome.It does great job of keeping my teeth from wreaking havoc on each other. And for the price, it is just what you need.

Sentinel is the best!! I'll save you from a lot of wasted time. I've been a teeth grinder for many years. My jaw is a wreck. I've had dentist made guards, store bought guards, and I've tried other online labs. Sentinel is the ONLY company that has been able to help relieve my jaw pain. The Sentinel guards fits. it's comfortable and durable. This is a high quality service and the best I've found. Save yourself time and money and go with Sentinel!!!

This product is the real deal! I'm writing this review because I recently took my custom night guard that I received back in April to my dentist. I expected him to tell me that it was crap and that I needed to purchase a night guard through his office. Instead he said it was a very well made, great fitting guard. I'm very pleased with the high quality, commitment to safe products and the price! Keep up the good work!

My nocturnal tongue biting issue had gotten so severe that I was in pain constantly. I tried ointments and the cheap night guards you can get at drugstores. None of it worked. A friend recommended this company to me. I messed up my teeth impressions the first time but I was sent new materials and an email explaining what I had done incorrectly. I was able to do my molds correctly the 2nd time. When I did receive my new guards I was impressed by the quality and care of crafting. I noticed a difference the very next morning in my pain level. Within a few days, my tongue had healed. I wear these religiously and want to share my experience here. Great for severe tongue biters!

Thoroughly surprised! I'm very pleased with my purchase. Great quality at a great price!

I LOVE the fit of this night guard! I had tried one from my dentist at a cost of $600. Wore it for 4 nights and threw it out. I tried the store bought guards with no luck. Figured I was out of options until I came across your website. Customer service was great at answering my questions and the guard fits FAR better than the others.

LOVE my new guard and the commitment this company has to using safe ingredients. I had an allergic reaction after using one I bought from Walgreens, a boil & bite. I appreciate the transparency of the materials used. This is high quality and the fit is perfect!

It works! My dentist had ordered me a guard for my cheek biting problem and after just 2 nights I knew there was no way I was going to be able to wear it. It was a hard guard unlike these soft ones. It pressed against my teeth causing me to wake up with pain and soreness. These guards are very comfortable and prevent my teeth from catching my cheek and doing damage. Job well done Sentinel team!

I originally ordered the hard night guard but found it to put too much pressure on my teeth. I contacted customer service and they made me a soft guard as part of my satisfaction guarantee. They even refunded me the price difference as the soft guard is a little less than the hard. Their customer service is excellent and they have gained a customer for life. Thank you!!
