Customer ratings & reviews

A++++ SERVICE IS REMARKABLE! I HAVE RECOMMENDED YOU GUYS TO SO MANY PEOPLE! I JUST LOVE YOUR PRODUCTS> THANK YOU!!

I have been grinding my teeth at night for many years but had put off buying a night guard because of the high price my dentist charged for one. Back in 2015, I read rave reviews about Sentinel and decided to give the 2mm Sentinel Hard Dental Night Guard a try. The guard has worn a bit in some spots, but it is still totally usable and going strong more than 3 years later! I couldn't be happier. Thanks Sentinel!

Couldn't be happier with my purchase. Fast delivery and A+++ service!

I saved so much money!! I was worried about taking my own dental impression but this company goes the extra mile to make sure it's an easy process. I actually enjoyed taking my teeth mold! The fit of my night guard is fantastic. Will definitely order again when the time comes. Very satisfied customer!

I've had bad TMJ for many many years. My dog chewed my last one. Customer service said this is common and that they're attracted to the saliva? I don't know but I wasn't sure this would work for my TMJ because I've read that I might need a more complex appliance that moves the jaw into position. I'm happy to report that the hard night guard has offered much relief from my jaw pain and popping. It is comfortable and hard and offers the proper jaw support I need. I'm even happier to report that I saved hundreds of dollars. Much thanks to you guys!

Fast, friendly service at an unbeatable price!

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

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.

Where do I start? This mouthguard is by far the best I've ever had. Very professional process from start to finish. It is perfect. I did not think I would be able to wear a mouthguard comfortably throughout the entire night. I've never had such a perfect fitting, comfortable mouthguard.

I LOVE Sentinel mouth guards! I've been ordering from this company for at least 5-6 years. Always quality products, wonderful service, and especially unbelievably great prices! Don't pay the dentists' high prices - buy from Sentinel and save money for the exact same thing your dentist makes - at a fraction of the cost!
