Customer ratings & reviews

Best nightguard I’ve ever owned. Customer service was so helpful. Ive tried several nightguard companies & this one is the best (without question).

A perfect fit !

This mouthguard fit very well on the first try! I used another company previously and had to send it back multiple times and just gave up since they never got it right.

Great fit at a great price!

I really like my new Sentinel Custom Dual Laminated Night Guard. The process was so simple. As soon as I put it in, I knew it was going to be so much better than my old night guard. The fit is perfect and it is so comfortable. I would recommend this product and company to anyone needing a night guard. And the price was a fraction of what my dentist wanted to charge for one.

You guys are great

Saving my teeth!

Perfect fit - I feel protected from cracking any more teeth and I sleep deeply because of the comfort!

Custom Dual Laminated Night Guard

Great product, excellent service

I couldn’t be happier with my new mouth guard. My dentist was impressed as well. Thanks Sentinel

Much better than boil and bite -was concerned with microplastics

Light, tough and can talk with it. Much less and more durable plastics so most likely less microplastics to ingest.

LOVE IT!!!!!

This little mouthguard has been a lifesaver for my jaws. It is much more comfortable than the ones I have purchased from my dentist, who told me I had to pay for TMJ evaluation. Your mouthguard has alleviated all of myl jaw pains! I will continue coming back for more as needed, from YOU! Thank you! And I can save thousands of dollars seeking out TMJ treatment.

Night guard perfection

As usual the guard was a perfect fit. I like the dual layer guards for sleeping. This is probably the 4 guard I have ordered and not the last.
