Affordable Online Replacement Teeth Retainers

You finally got the teeth you’ve always wanted. Let’s keep them that way!

After braces, your teeth are vulnerable to shifting. Teeth shifting can easily happen if you don’t wear your retainers consistently.  This last set of upper and lower trays can be costly through your dental office.

Protect Teeth From Shifting and Protects Against Bruxism

Essix Plus Dental Retainer material is an upgraded version of the standard Essix Retainer material.

This stronger, more durable material not only keeps your teeth in place but also protects against teeth grinding and jaw clenching.

Skip the Unnecessary Medical Bill 

Purchase your upper and lower clear teeth retainers direct through our lab by taking your dental impressions yourself!

Please note our teeth retainer set is to be worn AFTER your teeth have finished orthodontic treatment. These dental retainer aligners are to be worn to keep your teeth from shifting now and in the future.

Product Reviews

  • CM

    These are the best retainers I’ve had for fit and comfort.
    I have nothing but positives to say. Affordable, very well made and great customer service. *****

  • Michelle M.

    I almost never leave reviews but this is worth taking the time. The customer service is outstanding and helped ease my concerns about doing this online. The retainers themselves look SO MUCH BETTER than the ones made from my orthodontist. They technicians must be artists! Do yourself a favor and order from this company. You won’t regret it!

  • Darren J. Griffith

    I didn’t get a good impression of my back molars on my lower teeth (uppers were fine). The company quickly sent me a new kit explaining that I needed to retake my impression. I took my impression again and sent it off. Received my retainers about a week or so later. After wearing my retainers for a couple of weeks now I can say that I’m very happy with my decision. The price is much better than the dental office and I was impressed with the quality of their product and service. I will definitely be purchasing again when it comes time for a replacement.

  • Karen Cox

    Great service and great product! I replaced my retainers after my dog chewed up my old set. The old set cost me $450 from my orthodontist. The process was easy. The material feels very similar to my old ones. Maybe a little thinner? The scalloped top is different than my old ones. They were cut straight across but these do seem to fit better. Product is as advertised in the pictures. Would recommend!

  • John C. Smith

    My daughter needed a new retainer for her upper, hers didn’t fit right, rubbed her gums, she wouldn’t wear it and didn’t want to go back because she wasn’t heard when she expressed that something was off. Anyway, we had a new upper made by Sentinel and it fits perfect. So she’s back to wearing them nightly again, and I don’t have to worry about the investment we made in her smile being lost. So thank you again!

  • Lisa

    Worth it! Thank you Sentinel!

  • Tony Brown

    I bought this as an affordable option vs. going to get a customized piece from my dentist for triple the price. When I opened them I was immediately impressed with the quality. They’re formed so well, comfortable, and they stay in place all night. Pleased!!

  • Letricia Morrison

    Oh my gosh I saved so much money going this route! My dentist was going to charge me $500 A PIECE for new dental retainers after my dog chewed them. My teeth aligners are perfect. They fit so good. HIGHLY RECOMMEND!

  • Paul Johnson

    Love these retainers! I bought mine on Amazon and they are a better quality and better fit than my dentist. About to order your teeth whitening system too. Thank you for the great prices and service!

  • Emily Baker

    Be careful when taking your impression. They’re very particular about making sure the impression is perfect. I had to redo mine. They did not charge me for the new kit they had to send out. Very happy with my retainers. They’re cut and shaped with care. They fit like a glove. Just be sure to read all the instructions and capture all of your teeth evenly. Otherwise you’ll have to redo it.

    Amazon Review 5.0 out of 5 stars Great Affordable Mouthguard
    Process was easy and normal shipping speed. I had trouble making good impressions but Sentinel Mouthguard’s was able to send me new molding clay without extra cost. Fit beautifully. -L. Bryant

  • Cameron DeLouse

    These retainers fit great. I ordered 2 lowers for the same price as the upper and lower. My ones’ through my orthodontist were cut straight across. These are cut very nicely and fit much better!
