Customer ratings & reviews

Can't imagine why I will ever return to a dentist for a dental night guard. You guys are a serious money saver. Thanks bunches :))

Works just as good as my old night guard from my dentist I love how fast and easy the process has been. I use the bottom guard because it's less bulky. So far it fits perfectly, it's high quality and comfortable.

This team really does go to great lengths to meet customer satisfaction. I messed up my first dental impression and was quickly shipped another for free. Then wanted to change types after I received my soft night guard. They upgraded me and I just had to pay the difference in price. Way more flexible than my money hungry dentist! Great customer service.

A++++ Superb customer service. Superb product. I wear my Sentinel guard nightly and won't go anywhere else! Thank you!

Amazing quality and service! Couldn't get to the dentist because of the pandemic. I was having major pain in my cheek from subconscious biting during the night. Ordered these online and so glad I did. They fit great immediately out of the box. Excellent product and outstanding customer service!

The only lab I'll buy from. I'm reviewing the dental retainers but my husband has a night guard from Sentinel lab. We're both over the moon about the savings and the quality of the products. Have recommended to many friends and family. Consistent, great service all around.

These retainers fit great. I ordered 2 lowers for the same price as the upper and lower. My ones' through my orthodontist were cut straight across. These are cut very nicely and fit much better!

I ordered a dual laminate nightguard. The kit came quickly and following the steps was clear and easy. Even with Covid19 shutting things down I received my guard in good time and it fit like a glove. Unfortunately I had bigger issues that appeared with my jaw. I emailed my problems and Alexandra replied promptly but my problem requires a more complex solution that has to be done in person with a dentist. Sentinel refunded my entire purchase price just as they guaranteed when I mailed the guard back. I would definately use their company again if my family needs other products!

Finding the perfect nightguard can be a lot like the Goldilocks story. As a nightguard user, I have gone through many and it really does come down to personal preference and the ability to have a custom made nightguard for such an affordable price is a blessing!

Researched a few companies online before settling on Sentinel. My main grievance with the other night guard labs was that none of them answered the phone. Some didn't even have numbers to call (just emails) and they were slow to respond. Sentinel was prompt and happy to answer my million questions. They made me an exceptional comfortable and STURDY dental guard. Happy customer here! Thanks a ton!
