Customer ratings & reviews

I really like these night guards. I do not like soft floppy guards. They always seem to move around in the mouth and stretch out over time. These are hard and actually snap on to my teeth. The edges are smooth and not rough to the tongue or gums. This is my second guard from Sentinel and I ordered the 2mm. I would order more.

My nighttime grinding has not stopped ( I guess until there's a cure this is as good as it gets) but I am at least grinding away on some durable material instead of my teeth. I have noticed my jaw & facial pain has stopped & I am grateful for the two year warranty on these.

No complaints here. Price was righteous and works well even a year later. Looks professional/high quality and beats dental guards you'd pick up from a retailer like Walmart & CVS. Seriously, why buy junk like that when you can wait three weeks and get something fantastic that is fitted to your teeth and actually works!

Thank you for your responsiveness and great service. Greatly appreciated:) -M. Massey

Just wanted to let you know I love my mouthguard. Thanks so much! -Patty

I received my hard dental night guard & after two nights use I thought maybe I should have chosen the dual laminated guard. Contacted Sentinel & they happily complied with my request to change. By the time I received my new dual laminated night guard I had really adapted to my hard guard & decided to keep it after all (returned the dual laminated one). They were great through the process and went above and beyond to make a night guard that works for me. Highly recommended!

Customer service is on point! Well done Sentinel!!!

Snaps in place. Perfect fit! Thanks SM Team!

By far, the most comfortable night guards on the market. These guys take pride in their work and will work with you to your absolute satisfaction. A+++++

Love this night guard! Had to jump on here and give some feedback. From a person who was skeptical to buy online it was a nice surprise to get such a well fitting guard. I've gone through so many of these things (from my dentist unfortunately) and the quality is great. It fits perfect. These guys are good!
