Customer ratings & reviews

Great for teeth grinders! I needed a mouth guard for sleeping that wouldn't be too big and uncomfortable that I take it out during the night. Wanted one just for the top teeth and less bulky than the one I got from my dentist. Tried the OTC ones and I just remove them during the night, or they cause my teeth and jaw to hurt by morning due to the imperfect alignment. THIS ONE IS PERFECT. I read some reviews that said it was difficult to take the impression, but I watched the YouTube video and got it perfect the first try. Follow the instructions, use a mirror to place it and you won't have a problem. It is not necessary to bite down hard into the plastic when taking the impression. Really just stay focused on getting a good, even impression. Seems like a lot for a little piece of plastic, but my dentist wanted to make me one for $800, so this was a much better deal. And best part, woke up without a headache for the first time in years. Cheers!

Amazon Review 5.0 out of 5 stars Great Affordable Mouthguard Process was easy and normal shipping speed. I had trouble making good impressions but Sentinel Mouthguard's was able to send me new molding clay without extra cost. Fit beautifully. -L. Bryant

My teeth have never been whiter. Beautiful results. Thank you.

Very satisfied customer. I was blown away by the exceptional customer service and quality product. Would recommend to anyone.

Can't imagine why I will ever return to a dentist for a dental night guard. You guys are a serious money saver. Thanks bunches :))

Works just as good as my old night guard from my dentist I love how fast and easy the process has been. I use the bottom guard because it's less bulky. So far it fits perfectly, it's high quality and comfortable.

This team really does go to great lengths to meet customer satisfaction. I messed up my first dental impression and was quickly shipped another for free. Then wanted to change types after I received my soft night guard. They upgraded me and I just had to pay the difference in price. Way more flexible than my money hungry dentist! Great customer service.

A++++ Superb customer service. Superb product. I wear my Sentinel guard nightly and won't go anywhere else! Thank you!

Amazing quality and service! Couldn't get to the dentist because of the pandemic. I was having major pain in my cheek from subconscious biting during the night. Ordered these online and so glad I did. They fit great immediately out of the box. Excellent product and outstanding customer service!

The only lab I'll buy from. I'm reviewing the dental retainers but my husband has a night guard from Sentinel lab. We're both over the moon about the savings and the quality of the products. Have recommended to many friends and family. Consistent, great service all around.
