Product Description

Clear Essix Plus Dental Retainer Set

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 dental retainers direct through our lab by taking your dental impressions yourself!

Please note our dental 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

  • Romeo Ortiz

    A++++ Excellent experience. I highly recommend this company. Customer service was so great at answering my questions. Process was smooth sailing and my retainers fit perfect!

  • Caitlyn Brown

    Great option if you need to replace your aligners and at an affordable price!! *****

  • Abigail P.

    These retainers are even better than the ones I received from my ortho! They’re beautifully shaped and fit perfect. I lost my retainers and ortho was going to charge me an arm and a leg for a replacement set. Be careful taking your dental impressions. I had to redo mine the first time but they sent me a replacement kit for free! My advice is to watch the video a couple of times before you do it 🙂

  • Melissa Soderland

    I didn’t wear mine like I was supposed to and after a month my teeth shifted. Dentist wanted to charge me $500 for a replacement set. These are way more affordable and they fit better than the original ones my dentist made me! Thank you Sentinel!

  • George Hahn

    Great quality for the price.They keep the impressions on file for 1 year in case I need a replacement set. They send you the kit for your impressions first. There are 2 different sized trays and extra molding in case you mess up. It’s really easy to do, and my retainers were mailed back within a week or so.

  • Katie Poppy

    Glad I gave them a try!

    The fit was off when I received my lower guard. Upper fit perfect. They sent me a new impression kit and remade my lower retainer. Fits great! Happy with my purchase and would recommend. Suzanne in customer service is great!

  • Mary L.

    Originally ordered these on Amazon and loooooved them. They fit so perfect Way better than the dentist made ones! My dog got a hold of them so I ordered a new pair. The company keeps the impressions on file for 1 year from the date ordered. I got a 20% off discount because I didn’t have to take my impressions again. Second set came and it’s identical to the first set! Consistent, excellent product. I highly recommend!

  • Emily Hunchar

    5 stars!! Most comfortable retainers I’ve ever had!! The main difference between these dental retainers and the ones from my dentist is that they are made better. They trim these so that they don’t put pressure on your gums. Makes all the difference. I’ll only purchase from Sentinel from now on. Pleasantly surprised!

  • Corinne

    Went to order these on Amazon and can’t find them anymore. Are they only available on your website now? This is my third pair (dog keeps chewing them up). I’m so happy this service exists. So much less expensive than my orthodontist. Keep up the great work and please let me know if you plan to sell on Amazon again?

  • Chris A.

    This is my 2nd set of retainers from Sentinel. First set I got through Amazon. Communication is better when you buy directly from the Sentinel website. I understand after speaking with the customer service that they;re a third party seller on Amazon which means that you’re better off contacting them directly than going through the Amazon contact. They kept my teeth impressions in their file database and were able to make my 2nd set at a 20% discount. They fit just like the first. I’m very satisfied and will let others know about this great company.

  • John Feldman

    I recently lost my dental retainer. I only wear a top one so I didn’t need a lower one. Customer service said I could either order 2 top guards or get 20% off if I only wanted one. I ordered 2 top guards to be safe. I’m grateful I didn’t have to spend $500 at my orthodontist. Exactly as advertised.

  • M. Margowsky

    Upper retainer did not fit at first. Lower fit great. Contacted the company. They sent a new impression kit. This time I sent in a picture of my upper teeth to make sure it would work before I mailed it in. The 2nd guard fits much better. Customer service is helpful.
