This is my second time buying this because my dog got it the first time! I only wear this sometimes during the day and it has helped so much with my stress headaches! It’s easy, worth it and gives the best results.

This is my story, and I am totally sticking to it !!! My new "no bite your tongue and cheek" soft mouthguards are PERFECTION !!! I sent pics of my molds first and was encouraged to redo one mold. I mailed everything in. Return time was quick. The edges are so totally flat and smooth, no rough curled up material to irritate any tongue or mouth area. Also, they do not touch my gum line which is divine, just as I requested when I sent my molds in. They are like gloves for your teeth. I can barely feel them and they fit snug enough not to fall off but they are not too tight. Soooooo glad I found your company that makes these. I have literally spent a small fortune on other "Dentist Professional Guards" that NEVER met my need. I'm ordering back up second set for travel. Thank You ! Thank You !

I'm impressed with their professionalism and would highly recommend their services to anyone looking for help with a mouth guard for teeth grinding.

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
