Customer ratings & reviews

THIS IS IT!! I tried 2 other mouth guard companies before I settled on Sentinel and I won't be going anywhere else! From the customer service to the impression teeth process to the receiving my night guard, it was quick and painless. My night guard fits like a glove. I sleep with it every night and my jaw feels 100x better. If you want experience and professionalism, this is it.

Just writing a review for you guys which I rarely do but you deserve it. Thank you for being so responsive to my 50 questions. The mouth guard fits very well and I felt supported through the process. Thank you :) If you're shopping around, don't look any further. Sentinel Mouthguards is #1!

I received my Sentinel dental retainers yesterday in the mail and they're better than Smile Direct Club! They fit like a glove and the material is high quality. Very professional company. If you need to replace your retainers, this is the place.

I LOVE my no show guard and I wear it at night! Beats the standard night guards in comfort. No contest. The ones I used to wear would press against my front teeth. This guard style is the best I've found for my teeth clenching. I sleep soundly and my jaw pain is barely noticeable anymore.

PERFECT FIT!! This is a close to dentist quality as your going to get online. I have gone through several companies claiming to make quality products but Sentinel is the only one I've found that compares to my dentist made guard that I had for years. I would strongly recommend this product and company.

Hi Sentinel folks! I got my mouth guard and the fit is perfect. Thank you for sending the extra kit when I messed up my dental impression. Great, fast customer service, great product.

THIS WAS AT MY DENTAL OFFICE FOR $400! Once upon a time I paid $400 for this same set at my dental office. I'm amazed at the dental office markup. Thank you for offering high quality products at an affordable price. By the way, to anyone considering this, it's by far the best teeth whitening gel in existence. Great for sensitive teeth like mine and it gets my teeth so white. I also love that I can whiten anytime I need (months apart) because it's not a one and done system. A++

Perfect fit. You guys aced it. I was hesitant to take my own teeth impression but the process was easier than expected. I love my night guard and you've earned yourself a new fan. Nice job!

I originally ordered the soft guard but my teeth grinding is a little more intense than I thought it was. I saw wear marks on the soft one within the first month of use. Contacted Sentinel and they suggested a more durable type. After some back and forth, I decided to give the hard guard a try. Really impressed with the quality and fit. It's thin but offers the protection that I needed. I can sleep with it in easily and I'm even getting to where I prefer to sleep with it. Never thought I'd say that! If you're considering ordering a custom night guard online vs the dentist, this is the company. Fantastic work all around! A+++++++

My dentist has been telling my I grind my teeth and I finally did something about it. I ordered a night guard and a day guard. Both fit perfect and I particularly love the comfort of this day guard. Taking the impressions was a bit of a challenge for me, I had to redo them but they provide free materials so no problem. I also want to mention Sentinel's excellent customer service. Very friendly and helpful! I highly recommend~~
