PERFECT FOR DAYTIME USE Teeth impression process was easier than I thought and I received my mouthguard very quickly after sending it off. If you're like me and clench your teeth during the day, this is the mouthguard for you! I love the fit of it. I love that I can communicate easily. I do take it out when I eat and drink. My headaches and jaw pain are gone and I can feel that my teeth are thankful I'm not clenching down constantly! A lifesaver for business professionals.

This mouth guard is awesome! Easy to create your own teeth impression. My mouth guard came quick and fits like a glove!

Fits better than expected! It's by far the most comfortable mouth guard I've ever worn. It stays in place. I can talk with it in no problem. I will be back! Thank you!

The hard option is where it's at! I tried the soft type first and found that it was too flexible for my liking. Switched to the hard guard (they allow you to switch types if you're not satisfied) and this is EVERYTHING! My tension headaches are gone and I love how comfortable it is. I only had to pay the cost to upgrade ($20). Fast, affordable and the fit is fantastic!

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!
