Customer ratings & reviews

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!

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

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

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

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!

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.

Teeth molds were easy to take and the staff is incredibly responsive. I had a lot of questions about taking my molds of my teeth but the staff was patient with me and guided me through it. My retainers came back within about 1 1/2 weeks after sending off the molds. If I ever want or need new retainers I will go through this company again.
