Customer ratings & reviews

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

I love this company as a whole. The front desk lady is so nice. I had a million questions before I ordered because I have a bad gag reflex and was worried about taking my impression. They are patient and kind! Answered all of my questions. The impression taking process was much easier than expected. Final product fit nice! A little snug at first (first few nights) but I adapted to it and I love it.

Okay here is my experience with Sentinel Mouthguards: The process is easy but you have to pay attention to the impression instructions. I failed my first two attempts because I mixed the putty for too long the first time and the second time I distorted the impression because I moved the tray around while it was in my mouth. Both times were admittedly my fault but I was still frustrated at the time it happened. The customer service is excellent. They were prompt and friendly. Sent me a new kit with no charge. I got a great impression of my teeth. Waited about a week and 1/2 and sure enough my mouth guard came. It comes in a black retainer case. I tried it in and it fit well. Took me a few nights to get used to it but the quality is great and I saved so much money going the online route instead of my dentist. Not to mention the hassle of driving back and forth. I wear mine nightly. I called and they gave me some cleaning instructions. Pretty simple. Use a mild soap and a soft toothbrush. Make sure you rinse it well and dry it completely. This will prevent yellowing. I'm already seeing a few grind marks on the guard but better on the guard than my teeth grinding together! Overall, I highly recommend Sentinel Mouthguards. The experience was impressive and quick.

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 ordered a lower guard to start. When I received it, I realized my tongue likes to flick it up at night. I called the company and they switched me to an upper guard. I already had the upper impression on file with them because with these heavy duty guards, they require both an upper and lower teeth impression. Super easy and convenient! I was sent the upper teeth guard and it fits perfectly. This product is excellent and the customer service is amazing!

A+ service. I recommend to all of my family and friends!

I've been using this same pack of gel I got 9 months ago and I still have 2 syringes left! I whiten periodically whenever my teeth need a boost. I love this because I used to spend so much money on Crest whitening strips. I have everything I need to keep my teeth white any time I want. This really is the best bang for my buck!

I can't stand how bulky most mouth guards are. I perform better when my mouth guard is comfortable. What I love about these is that I get to choose the thickness. I went with a 2mm and wearing a mouth guard isn't an issue for me anymore. Thank you and God bless!

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!

Taking the mold of my teeth was a lot easier than I expected. The impression kit came to my house within just a few days of ordering. I watched the Youtube video and looked over the instructions that came in the box. Easy and straight forward. This process ended up being SO much less expensive than the dentist and I love how it fits and feels. I wear this while I'm lifting weights too. An extra perk!
