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

    This is going to sound like it’s not written by a customer but it is and I am a VERY HAPPY CUSTOMER. This may be the best purchase I have found. I’ve lost 3 sets of dental retainers and my mom was the one having to pay to replace them through the dentist. Well, I just ordered my second set of Sentinel retainers. Not because I lost these (not yet) but because I wanted a back-up ready just in case the inevitable happens and because they’re realistically priced/affordable I can pay for these on my own. A+++++

  • Elizabeth Evans

    Bought these for my daughter. Nice customer service and nice product. Very easy to work with and at a fraction of the dental office cost. I’ll take it 😀

  • Deb Jordan

    I absolutely love this product. I recently had to switch to the hard dental retainers because I made a mistake when I ordered and bought upper and lower soft night guards instead. Much to my disappointment, the soft night guards arrived and obviously did not help keep my teeth straight. I contacted Sentinel Mouthguards and explained the error.

    Customer service was excellent and the lab very quickly made my hard dental retainers and mailed them to me within a few days.

    They fit perfectly. They’re made extremely well. I wear them during the day & night. Very satisfied customer!!

  • Morgan K.

    Never thought I would be able to buy dental retainers online! So nice to not have to deal with my dentist again now that my teeth are straight. I just want to keep them this way and I also grind my teeth at night so it is comforting to know that I can reorder these if I grind through them because they keep my dental impressions on file. Sweet!

  • Renee A. Miller

    Really liking these. My teeth are so sensitive now that my braces are off so I was hesitant to try this product. After reading the reviews I decided to try. This is a perfect option for me. The clear retainers fit perfect. No sensitivity and I’m loving the price!

  • Jaime Cabott

    Teeth molds were easy to take and the staff is incredibly responsive. I had a lot of questions about taking my molds of my teeth but the staff was patient with me and guided me through it. My retainers came back within about 1 1/2 weeks after sending off the molds. If I ever want or need new retainers I will go through this company again.

  • Carole

    This was a replacement retainer for another I had from a dentist which wore out in a year and a half. The Sentinel retainer fits very well, is thinner even than the old one and the price more affordable. Customer service was excellent – the first retainer I received did not fit perfectly so I contacted them via Live Chat and response was timely and helpful. Sentinel recast another retainer and also sent another dental impression kit in case the new one didn’t fit. Well, the recast retainer fit just fine so no need to do another impression. When Sentinel says they stand behind their product and want the client to be 100% satisfied, they follow through!

  • Cara B.

    Took less than 4 weeks total from start to finish. I wish it was a bit quicker because I had a fear of my teeth shifting but nothing had changed and the guards arrived and fit perfectly. These are $300 at my dentist so I guess I’m willing to wait a bit to save the money.

  • Charlotte Belle

    Excellent quality and superior customer service. They fit better than my dentists!

  • Eric Lopez

    I was looking at paying $600 for replacement dental retainers after my dog chewed them up. I am grateful to have found your service! The impression process was easy. I thought I might gag on the impression substance because at the dentist they used a messy, goopy mixture that fell to the back of my throat but luckily the impression substance sent to me was not like that at all. The girl on the phone said it is similar to playdoh and that is exactly right. Even smelled like mint! I just wanted to let you all know that I appreciate this service being available online and if my dog ever gets a hold of my new retainers again I will be back!

  • Alicia Browne

    This turned out to be the best thing ever! I was able to make custom dental impressions for both sets of my teeth and received my set of retainers about two weeks after mailing the impressions back. The fit is outstanding & Sentinels customer service is amazing. I got such prompt response and their absolute concern for my health and safety was nice to see.

    Exactly what I needed! Thank you so much! -Heidi
