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 :)

I've been using Sentinel dental retainers for the past few months and I'm really happy with the results. They're practically invisible and comfortable to wear. I can go about my day with confidence knowing my teeth not shifting.

I live in the city and my orthodontist charges $500 for a replacement set of dental retainers! This is a cost-effective way to save and the quality is even better than I had anticipated! Comes with a mouth guard case for storage. Nice job Sentinel!

Received my retainer (just needed a lower) and it fits perfect! Really happy with the whole process. I'll be using you guys from now on. Great product, fast shipping!

Sentinel Mouthguards is exceptional! Super accommodating, friendly professional customer service. I showed my retainers to my dentist and even he was impressed!

This is my 3rd set of retainers from Sentinel due to my dog continuing to steal them off my nightstand. They give me a discount for being a returning customer and the quality has stayed consistently high. I'm always impressed with how beautifully they're made. Way better looking and fitting than my original ones from the orthodontist. Thank you for being of service to us poor folks with strange dogs!

Higher quality than my dentist!! I waited to review after receiving them even though they looked and fit great. I wanted to see how they hold up overtime. I'm pleased to report after 1 year my dental retainers still look and fit perfect! This is the real deal! Thank you Sentinel!
