Customer ratings & reviews

Messed up my impression the first time. Sent a picture in and they told me that it wouldn't make for a good night guard so I used the extra putty that was in the kit to try again. About 1 1/2 weeks later I received my guard. I'm glad they care enough to supply an extra putty pack for a retry and provide such friendly customer service. Will be back because I don't think this teeth grinding habit is going anywhere!

This is a quality product like you would get from a dentist. Thanks.

Great product! Great service! I totally recommend Sentinel!!

FANTASTIC TRANSACTION-TERRIFIC GUYS HIGHLY RECOMMEND 5 STAR!!!!

After 4 days if wearing my jaw feels so much better already.A+++

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.
