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

  • Sterling Carlisle

    The only lab I’ll buy from. I’m reviewing the dental retainers but my husband has a night guard from Sentinel lab. We’re both over the moon about the savings and the quality of the products. Have recommended to many friends and family. Consistent, great service all around.

  • Ayanna B.

    Love love love! Took a couple of days to break them in but now I’m wearing them all the time. I talk with them in during the day. Totally worth it for me.

  • Kristine Paul

    I was afraid these weren’t going to work for me because the ones my dentist made for me were uncomfortable but these popped in and fit perfect. Comfortable and very high quality.

  • Genia R.

    I have a small mouth and needed small tray sizes sent out. Sentinel was very accomodating. Made the initial purchase 3 weeks ago and I already have the custom retainers. This company will be my go to whenever I need to replace my retainers in the future.

  • William Morel

    I can’t say enough good things about this product and the companies customer service.
    The secret to getting a good fit is to read the instructions carefully and make sure that you submerge all of your teeth including the gum area evenly and do not remove until your 3 minutes is up! I had to learn this the hard way but the company sent me new impression kits at no cost! Second attempt worked! Very responsive and easy to work with. The guards felt a little tight on my teeth at first but became comfortable after a few nights.

  • Amanda D.

    Excellent fit and highly recommended! The process is easy. I was a bit wary about ordering online but after reading the reviews on this company I decided to give it a try. Great all around! Thanks Sentinel Team!

  • Phillip Blatner

    It’s like the dentist ones. Pleased with the fit. I ordered the teeth whitening too and will review the whitening once results are in.

  • J. Collins

    Better quality than what I got at my dental office. I would definitely recommend Sentinel Mouthguards to family and friends. I am very pleased with the fit of the product and customer service.

  • Mike A.

    Great quality and great company! I was so happy when my retainers finally arrived to my door! I wasn’t sure if my impressions were going to be good enough so I emailed a couple of pictures of the impressions and they said it was best to send new impression kits to me to retake them. I got it right the second time and received my retainers yesterday! The fit is perfect. Thank you!

  • S. Blascoe

    I am not the type to write reviews but this product is outstanding and really works as advertised. Highly recommend to anyone who needs to keep their teeth straight after braces but not willing to pay the dentist’ price! Will be buying again if needed.

  • Todd R. Theurer

    I wanted to write this review because my experience has exceeded my expectations. I have been wearing my dental retainers for 9 months and I also grind my teeth at night and ended up doing some damage to the retainers. I contacted Sentinel and they asked me to upload a picture to their email of the wear on the retainer. They still had my impressions on file and made me new dental retainers because I was still within my 1 year warranty. I don’t know of any other dental office or lab that would do that. They paid for the shipping and everything. I am impressed with the level of quality of the product, the customer service and the willingness to back up the warranty. Impressive and refreshing company.

  • Adrian N.

    I spent over $500 from my FSA account to have my final custom dental retainers made by my dentist. They fit perfectly, but apparently I grind my teeth too and had to get them replaced. There was no option from the dental office given except to order another set for $500. Umm… no! After reading the rave reviews for the Sentinel Mouthguards on Amazon, I decided to give them a try. I must say that I am extremely pleased and highly recommend them. The directions were easy to follow, I created a great fit myself. Not to mention that it saves me $360! I’m never bothering to order another set of retainers from the dental office. Literally saved me hundreds. Thank you!!
