Customer ratings & reviews

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!

THE MOST COMFORTABLE! 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.

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

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.

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!

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

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 :) -Abby

THEY'RE PERFECT! I travel a lot for work, so the fact that I can pop my clear dental retainers in and out easily is a game changer. Plus, they're comfortable to wear for extended periods of time. I don't have to worry about any discomfort while working long hours

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!
