Customer ratings & reviews

The sentinel team was very responsive to my needs even after I messed up my dental impression. They provided me with great feedback throughout the process and I was able to take a great impression with the extra putty pack provided. If you're on the fence just go ahead and do it. I highly recommend this company to everyone!

I just got my Sentinel guard in yesterday and as I'm sure many others are, I was skeptical to order online. I'm happy to report the impression process was much easier than I thought it would be and the guard is the most comfortable one I've ever had! Looking forward to wearing it at work. Hopefully these daily headaches will stop once and for all!

I love my current guard so much, I ordered 4 more during your black Friday sale! The difference between your price and the dental office is exceptional!

The impression is easy to take and the quality exceeds its price. I like that I can get a replacement for free if I grind through this one within 6 months AND that I don't have to take my impression again (they hold on to it). The way my stress level is, I might be grinding through this quicker than I think!

This is the best mouth guard I've found for daytime use. I clench my teeth horribly during the day. I use this while I'm at the gym and in the office. This is a great article they sent me about how to take care of it and keep it from turning yellow. I've had many many night guards before and if you don't take care of them properly they will turn a nasty yellow! Thank you Sentinel team. You have a customer for life!

LOVE my new guard and the commitment this company has to using safe ingredients. I had an allergic reaction after using one I bought from Walgreens, a boil & bite. I appreciate the transparency of the materials used. This is high quality and the fit is perfect!

An absolute tooth saver! I have the hard night guard for nighttime and just received this day guard. It's a perfect fit. I love wearing it during the day and no one can tell I have it in! -Pam

Just placed an order for a second one to have as a backup. The fit is perfect! Thank you~

I didn't realize how badly I was clenching my jaw during the day until I started having headaches! I work from home but on a computer for long periods of time. This works so well. The ordering process was easy. My headaches are GONE and I feel so much better knowing that even if I can't stop clenching my jaw during the day, my teeth are protected! 5 stars!!

I found this to be perfect for so many reasons. 1st I found these to be so helpful when I realized I was suffering massive headaches during the day from clenching my teeth. I found the day guard and then later saw that they had other varieties as well. The 3mm hard night guard is perfect for my nighttime grinding and I wear the thinner day guard at work. Being able to have them both and save a lot of money is wonderful. I got 20% off my thicker nighttime guard because the lab already had my impression on file. All you have to do is ask for the coupon code! I highly recommend these!
