Customer ratings & reviews

Bought these for our both my husband and I and they are a hit! The shape is different from my previous guard but is nice and comfortable for sleeping. Shipping was quick and the customer service friendly.

This is it!! I have tried so many mouthguards by other companies and dentists. They always get it wrong. I expected the same this time but I was pleasantly surprised! The fit is perfect. Not too tight. Not too loose. It fits perfectly. I sleep all through the night. Thank you! You have a customer for life <3

I would agree with everyone below. Sentinel's customer service is #1. I received several emails throughout the process keeping me informed. I was thinking to myself another automated email system but they were all informative, useful emails with my tracking information etc. They are quick to respond through email as well and I received my night guard within about 3 weeks from the order date. *****

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.
