Customer ratings & reviews

This is one of the most comfortable night guards I have used. But most importantly is the outstanding customer service! Although an easy process to make the impression, I messed one of these up and Ashley at Sentinel was extremely helpful and sent another out. I ordered two of the harder material night guards, one for me and the other for my wife. After receiving the harder one, my wife preferred the softer material. I contacted Sentinel where they were quick to respond saying one will be made and sent out. So much easier (and less expensive) and convenient doing this at home vs. at the dentist. Highly recommend Sentinel.

Never thought I would be able to buy dental retainers online! So nice to not have to deal with my dentist again now that my teeth are straight. I just want to keep them this way and I also grind my teeth at night so it is comforting to know that I can reorder these if I grind through them because they keep my dental impressions on file. Sweet!

Thankyou. Your product is awesome. This is my second mouthguard (I lost the first ) and I have recommended you to Dentists and Doctors. It is so comfortable and unobtrusive. Regards Tanya

Received my Mouth guard fits Perfect!!! -Warren White

Great product and great customer service! If I can do this process, anyone can! The impression process was what I was most worried about and it was so easy. I don't usually write reviews often but this company deserves a mention. Sentinel goes above and beyond!

Wasn't sure what to expect but my guard is snug and comfy! I absolutely love this night guard and highly recommend!

Great value for the money!

Amazing company! Very easy, simple process!

Really liking these. My teeth are so sensitive now that my braces are off so I was hesitant to try this product. After reading the reviews I decided to try. This is a perfect option for me. The clear retainers fit perfect. No sensitivity and I'm loving the price!

This the only mouthguard I've ever been able to wear. It's worth every penny.
