Product Reviews

  • Gene Howe

    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,

  • Chase H.


    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!

  • Brett B.

    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 🙂

  • Amanda J.

    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.

  • Michael Way

    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!

  • Dana Bracht

    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!

  • Jason Riner

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

  • M. Massey

    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!

  • Terese D.

    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!

  • Ezra Elliot


    Initially, the upper retainer fit great but my lower was off. Contacted customer service and was promptly sent a new kit. They remade my lower retainer quickly and it fits perfect! I saved a lot of money and the quality is excellent.

  • William Peterson

    Thank you for making my dental retainers. They fit better than the ones I received from my orthodontist. They seem to be the same quality material and for a 1/3 of the cost! So happy to have found you guys

  • Salina Brooke

    After I lost my dental retainers I was surprised at how quickly my teeth started to shift. I decided just to get a less expensive replacement set and wear them consistently this time. I went to my orthodontist and was quoted $550 to replace them. No thanks. I found Sentinel Mouthguards online. Took my own dental impressions and a week later, I was mailed a perfect set of upper and lower retainers. $350 LESS THAN MY DENTIST. Thank you for this affordable option.
