Customer ratings & reviews

I highly recommend the dual laminated night guard. Like many others, I chose this company over my dentist because of their stellar reviews and the affordable cost. It took some time to find just the right customized fit, but Sentinel was totally understanding and worked with me until everything was perfect. Needless to say, they stand by their word on customer satisfaction. This particular guard is great because it gives you both the durability of the outer acrylic layer, as well as the softness of the inner, more pliable layer. The fit is very precise, and the guard stays in place through the night. Overall, wonderful customer service and a great product at an affordable price.

Oh my gosh! It fits so well! I didn't think it would fit so perfectly to my mouth and I slept better than I have in years!! A+++

By far, the most comfortable night guards on the market. These guys take pride in their work and will work with you to your absolute satisfaction. A+++++

My teeth are really flat. I just needed something to keep things from worsening and it's nice to find an inexpensive alternative. Thanks Sentinel!

I only wish I would have know about Sentinel sooner, a friend referred me here and I'm completely satisfied. Great company!

I bought my Sentinel guard back in April. I cannot sleep without this night guard or I'll wake up with severe jaw pain!! So thankful for companies like this that cut out the middle man because the ones from the store are the worst and the ones from the dentist are too expensive!

This is my first time using Sentinel but my 4th custom Mouthguard and its by far the best one out of the 3 that I've had.. Hands. down. Its not super bulky or cheap feeling. My others would hurt my mouth after about an half an hour from being stretched out. I can breath a lot better, I can drink water without taking it out, and I can speak clearly. I highly recommend Sentinel.

Great service! Great product! Thanks!

Love this night guard! Had to jump on here and give some feedback. From a person who was skeptical to buy online it was a nice surprise to get such a well fitting guard. I've gone through so many of these things (from my dentist unfortunately) and the quality is great. It fits perfect. These guys are good!

I was unsure if I could get a custom night guard online to help keep me from grinding my teeth. My Dentist quoted me $500 for a custom night guard and I decided to look online for another option. Glad I did. I Had my impression kit within 2 days after my order, from there it was really easy. It also came with step by step instructions on how to take my own impression, along with a website address of an instructional video (which I like since I learn easier visually). I mixed the putty and Took my impression and was done! sent it back in a nice little prepaid envelope they sent with the kit. Had my custom night guard within the week. FITS PERFECT! The night guard fit my teeth nice and snug but no added pressure or discomfort and I thought sleeping with guard would get annoying but I don't even notice it, been sleeping better and my jaw pain has gone away.
