Customer ratings & reviews

I had a small issue with the initial fit of my night guard. I contacted Sentinel and they promptly sent me a replacement. Fits extremely well and couldn't be happier with the professional and timely customer service!

As I get older I've realized the importance of my teeth. I feel so much better knowing that I'm taking the right measures to make sure they last as long as they possibly can. I've tried many mouth guard types and not only is the Sentinel guard affordable, it is comfortable. I chose the 2mm Dual Laminate and am very satisfied. Thank you@ Sue & team

What a relief - excellent bargain, much faster than the dentist's office, easy to follow instructions, seller easy to contact and very helpful - highly recommend. Thank you and I'll be purchasing again with you when this one needs replacing in a few years!

5 *****I have been wearing night guards for 10 years and this is the best looking and best fitting one I've ever worn. Beautifully crafted and polished perfectly. I'll be ordering one for my wife soon. Thank you for the excellent product and service. -Harold

I've bought 6 of the Sentinel soft nightguards over the years for myself and various family members. They last for years, and if you buy more than one they get cheaper. Some people can buy generic nightguards, but I need ones fit to my teeth. You can go to various doctors and get customized nightguards, but if you can follow simple directions you can get a custom fit at home using this method. I was nervous I'd screw it up the first time, but they have always come out right. I had serious bruxism for years, and tried most everything. I am convinced that these nightguards, combined with changes in habits have been instrumental in mitigating my pain. Of course every case is different, but I swear by these.

Where do I start? Not only do I have an HSA account and was able to get this purchase covered by just sending in a copy of my invoice but I have never had a more comfortable night guard. I've been through so many dentists and night guards over the years. These guys are pro! BIG THUMBS UP!

I had first ordered the hard night guard and couldn't get used to it. I was pleased to learn that Sentinel will work with you to make sure your satisfied. After talking to a customer service rep we decided to try the dual laminate type. I'm very happy with the choice and have been wearing this dual one for 4 months. No issues and my jaw pain is gone! I will recommend them to any teeth grinding sufferers. Amazing job!

Absolutely amazing product. I have crooked teeth and most regular trays from the store just don't fit at all. I got these and now I can do jumping jacks while whitening! Not that I do that but still. The molding process took about 5 minutes. Mixed the putty for a minute, placed in tray & gently submerged my teeth. The whitening system is so good. Whitens my teeth incredibly well & I can just have them on at work or at the mall and you can't tell. Nice firm material makes them easy to wash with cold water.

This turned out to be the best thing ever! I was able to make custom dental impressions for both sets of my teeth and received my set of retainers about two weeks after mailing the impressions back. The fit is outstanding & Sentinels customer service is amazing. I got such prompt response and their absolute concern for my health and safety was nice to see.

I have been using the night guard now for over a month. I can clean it with a light soap, my teeth don't ache. It is comfortable and has been a minimal /not bad adjustment to my sleep routine. I would and have been recommending this to all of my family/friends who grind or clench their teeth. I am currently disciplining myself to wear the guard every night all through the night. This is definitely an excellent product to help in my bruxism.
