Fast, affordable, excellent product! Simply great! Thanks Sentinel team!

Received my night guard about a month ago and have been using it nightly. I went with the .80 hard acrylic dental guard because it's sturdy and I need to wear it every single night. It took me about a week to get used to it. It's thin and it fit well but having something in my mouth at night just took some time to get used to. I saved a ton and I feel really good about my purchase. Communication was excellent with Sentinel. I messed up my impression the first time around but they were great about sending me another one right away. Recommended!!

This is my second experience with an online night guard company, The first one gave me a shoddy product and then they wouldn't answer their phone. I shopped around this time. Some other labs I saw didnt even have a phone number to call. Sentinel Mouthguards answered my call and tolerated my million questions. Got the kit within a few days. Th whole process took about two weeks. I am very pleased. Definitely will use this company from now on.

I was really nervous about ordering because I have missing teeth on both my uppers and lowers and was worried about how well it would fit. Received my guard today and wow! The fit is just flawless. I'm glad I went with the soft because I think maybe the hard would have been too difficult to get this great of a fit? Maybe I'll try the hard one next time. Thanks a ton!!!

100% perfect fit. Such a difference from my other one. WoW! Thank you!

One word- PERFECT! I had three different guards made by my dentist before I took a chance & ordered through Sentinel. The three guards from my dentist were all uncomfortable & bulky. A complete waste. I was so discouraged. I chose the 2mm night guard and it is perfect. My headaches and facial pain are gone. I'm very happy! All around great experience!

Will order again!! Thank You!! My experience has been wonderful. So glad i found you guys!

I checked out a few sites before choosing this one because I wasn't sure if I was able to get a good fitting night guard since I don't have the straightest of teeth. I was worried only a dentist could get the right impression. I went for it anyways and it has fit perfect since. No more jaw pain and I'm sleeping better. Sentinel was really easy to work with and I'm very impressed.

Both thumbs up! Terrific job. Saved me a ton. Heed my advice people: Keep these things away from CATS! This is my third one in about 6 months because of my little guy Rupert! Luckily they're affordable!

I clench my teeth. I don't grind but I kept cracking crowns which is just ridiculously expensive. The thought of wearing a mouth guard over my teeth while I sleep just seemed unlikely. I tried the ones from CVS with no luck. I asked for a thin version of the soft guard and it's perfect! Sleeping with it in took some training but if I have to wear one I think I got the best one I could get. Thanks a million guys!
