Customer ratings & reviews

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!

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.

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!

Perfect fit A+++

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!
