Retainer

My retainer is perfect. Thank you so much.

Great Fit!

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!
