Customer ratings & reviews

I drink a ton of coffee and I just live my teeth whitening trays. Keeps my teeth from yellowing because I don't want to give up my coffee!

Excellent fit and highly recommended! The process is easy. I was a bit wary about ordering online but after reading the reviews on this company I decided to give it a try. Great all around! Thanks Sentinel Team!

Fabulous service!

We use these in our family. My mother wears one, myself and my husband. We are a family of teeth grinders! We love these night guards and the great team at Sentinel!!!!! So bright and cheerful, they are always there to help us. These guards lasts a long time. Will absolutely order more in the future.

Fast, friendly service at an unbeatable price!

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!
