Customer ratings & reviews

Great product and service

I've ordered a dental retainer from my dentist which was very expensive. It cracked repeatedly and had to be replaced 3 times. I got tired of dealing with them so I decided to try Sentinel based on the good reviews. They've been so responsive, answered my questions promptly and sent out the kits quickly. The retainer has held up beautifully and they look as new as when I received them. Their Customer Service is excellent. I won't go anywhere else.

My retainers have arrived. They're awesome. Much nicer than the very expensive ones I got from my dentist. Thank you!

Just received my new retainers in the mail and they're perfect! Exceptional job in craftsmanship from a company that cares. The impressions were easy to do and included instructions + a helpful video of a woman taking her dental impression from start to finish.A+++++ HIGHLY RECOMMEND!!

Just as good as my orthodontist made ones. Easy and quick service at an affordable price! 10/10 I recommend!!

Amazing!!! Needed an upper retainer and like many others have said, it looks and feels even better than my dentist made one. Fast and friendly customer service, easy to use teeth impression kit and the retainer is PERFECT! Highly recommend!

I received my Sentinel dental retainers yesterday in the mail and they're better than Smile Direct Club! They fit like a glove and the material is high quality. Very professional company. If you need to replace your retainers, this is the place.

The only dental retainers I can actually wear! I originally purchased these on Amazon 2 years ago and was so impressed. I'm scared about my teeth shifting back so I continue to wear dental retainers at night just in case. I just purchased my second set after my dog tore my old ones apart. Again! These fit like a dream. When I got the ones from my dentist, I couldn't wear them. They dug into my gums so bad. But these snap on. They fit secure but they don't hurt. I have recommended Sentinel to all of my friends and family and will continue to do so. Thank you!

High quality retainers!! I received my new set of retainers after my dog found mine and they are HIGH QUALITY! They look and fit even better than my orthodonist made ones. They're affordable, customer service is great and they were made and delivered fast! I highly recommend this service,

DON'T PAY THE DENTIST OFFICE PRICES! I feel like I should be telling everyone I can about this. I lose my retainers fairly often or my dog gets them so replacing them through the dentist became so expensive. I was skeptical about ordering because I thought there's no way these are the same. I received my retainers and immediately noted how well they're made. Tried them on and they fit better than my ortho!!! A+++++ Excellent service!

I was a little worried about the process but glad I did it! My custom retainers are made better than the ones at my dentist for hundreds of dollars less. I had to redo the first impression but they let you send in photos and they give prompt feedback. They included an extra set of putty in the teeth impression kit so I retook it that same day. Overall, I'm extremely happy with my retainers. I'll be back again when I lose this set :)
