Customer ratings & reviews

Bought this for my daughter. She said on a scale of 1 to 10 it is a 10 in comfort! She's been a longtime teeth grinder. The dentist said she would grow out of it as a child but here she is at 18 still doing it. We have tried the walmart guards and they never were comfortable enough for her to wear during sleep. Truly the best! We looked around and decided on Sentinel. Glad we did. Thank you!

My daughter has seizures and has had terrible pain from biting her tongue during her episodes. I searched for a long time to find something that would help her. The dental impression process was very easy to do. I helped her with her impressions and we received two very well made soft night guards. She wears them nightly just in case she has a seizure. So far so good. They're very thin and soft yet firm and I feel better that she has something protecting her from damaging her tongue any more.

The best on the market!! I couldn't pass on the great price these were being sold for. I followed instructions for taking my teeth mold they gave me and ordered a blue mouthguard. When I got the guard I knew it would fit well but the fit is far better than I imagined. It's not too bulky. It feels good in my mouth. Very uncomfortable. Even wearing it while talking is easy. Again, very uncomfortable. Thank you.

Well worth it!! Easy to follow directions. Great for both beginners and experienced dental night guard wearers. Only would have loved a faster turnaround time but I'm pleased with the final product. Now I can't wait until my nighttime grinding is cured so that I can quit sleeping with plastic in my mouth!!

Very happy with the entire process. I'm never going back to OTC mouth guards again!

I am a horrible nighttime teeth grinder and clencher. I have managed to chew threw so many of these things. I am very happy with this guard. I love that the company keeps impressions on file for 2 years because I don't enjoy taking my dental impressions and I may need another soon!

Not bulky. The fit is very nice. I have used this for 3 nights so far and I think this may be the best purchase I've ever made. I highly recommend this product for anyone who experiences pain from teeth grinding.

Outstanding product and service! Sentinel's customer service is unparalleled!The care and individual service I received is worth writing a review for. I greatly appreciate the excellent customer service and their willingness to go above and beyond.

I purchased a 1 mm bottom guard. The process was easy to take an impression. The guard itself actually fit very well and got used to it within a few nights. I tried others but they were way too bulky, not allowing me to sleep with my mouth closed. I have had this guard for well over a year and just now starting to see signs of wear. I will be ordering another.

I clench my teeth a lot at work, and I've tried many night guards of all types. They never form well and they're bulky. This night guard is nice. I can close my mouth, talk, drink water, etc. It's the best of its kind I've used. I would highly recommend it.
