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

  • 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!

    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.
