Customer ratings & reviews

We love this service. My wife and I both use the Sentinel night guards because they're very comfortable, affordable and now that the Sentinel lab has our dental impressions on file we can order future guards with ease if we grind through these!

They stand by their warranty! I wore through my night guard after 6 months. Not only did they replace it for free, they made me a thicker one that will last longer and didn't charge me a thing. I just bought this for my sister too! Teeth grinding must run in my family! Great product, great service.

A++++ SERVICE IS REMARKABLE! I HAVE RECOMMENDED YOU GUYS TO SO MANY PEOPLE! I JUST LOVE YOUR PRODUCTS> THANK YOU!!

Relieved my teeth sensitivity!!! I was having the worst "zingers" from grinding my teeth. I would wake up with sharp, intense nerve pain. I knew I needed to wear a mouth guard but couldn't find anything comfortable. I went with the medium thickness and it's perfect. My teeth sensitivity is gone and I get better sleep. Great service!

Couldn't be happier with my purchase. Great product for the value.

Fit is spot on. I was skeptical but they nailed it. I highly recommend!

Perfect fit! Great service!

I had trouble getting a good enough impression but customer service was patient with me. I also needed to wait to do this because of some dental work. So not only did they let me hold onto the impression kit for 6 months while I was getting that completed, I messed up my impression when I was finally ready and they sent me a new kit for free! This company has earned my business for years to come. The guard is a perfect fit and quality is high. I will say be careful when mixing the putty and watch your time. I went over the time (mixed too long) and the putty hardened like a rock the first time. Second attempt was successful. Also, they tell you to send a picture in so they can see if it's a good impression before mailing in. I would recommend doing this. They respond fast and it saves time.

I have been grinding my teeth at night for many years but had put off buying a night guard because of the high price my dentist charged for one. Back in 2015, I read rave reviews about Sentinel and decided to give the 2mm Sentinel Hard Dental Night Guard a try. The guard has worn a bit in some spots, but it is still totally usable and going strong more than 3 years later! I couldn't be happier. Thanks Sentinel!

FAST AND AFFORDABLE!! A+
