Customer ratings & reviews

The most comfortable night guard for grinding! These are the best. I no longer wake up with headaches and a sore jaw. The turn around time and customer service was stellar. Don't hesitate to buy! Save your teeth!

Excellent service! It has helped my jaw pain out tremendously. Much appreciated -Devon

I'm putting the review here because this is the intended purpose. That is, to stop my cheek biting but I actually ordered the hard dental retainers for this and it works exceptionally well. I don't know if anyone else has ordered the hard ones for cheek biting but they work too. Basically, the plastic surface disallows the cheek to "catch" between the teeth. I'm sure the soft ones are fine.

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!
