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!

I was unsure if I could get a custom night guard online to help keep me from grinding my teeth. My Dentist quoted me $500 for a custom night guard and I decided to look online for another option. Glad I did.
I Had my impression kit within 2 days after my order, from there it was really easy. It also came with step by step instructions on how to take my own impression, along with a website address of an instructional video (which I like since I learn easier visually). I mixed the putty and Took my impression and was done! sent it back in a nice little prepaid envelope they sent with the kit.
Had my custom night guard within the week. FITS PERFECT! The night guard fit my teeth nice and snug but no added pressure or discomfort and I thought sleeping with guard would get annoying but I don’t even notice it, been sleeping better and my jaw pain has gone away.

I ended up leaving behind my night guard on a recent vacation in Hawaii. I called the hotel but to no avail. My dentist wanted 400 to replace it!! I couldn’t believe it. Sentinel was a really easy, and affordable solution to an unfortunate problem. Got the same exact night guard my dentist wanted to charge me 400 for at a fraction of the price. 5 STARS!

Two thumbs up! Excellent

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!!

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!

I have pretty extensive damage from grinding my teeth for years. I’ve cracked three crowns and broken a veneer from teeth grinding. Needless to say, I should have been wearing a night guard a long time ago. Fast forward thousands of dollars later, I found Sentinel through an article online and decided to go for it. No complaints. The guard serves its purpose well. Thanks Sentinel:)

Just wanted to leave a quick review to let you all know how impressed I am with your customer service and high quality night guard. I have been through many of these (unfortunately paid way too much through my dentist) and I am just over the moon impressed. I highly recommend Sentinel Mouthguards Co. to anyone and everyone. Kudos!

I’ve been paying $600 for a night guard (and replacements) for years through my dentist. I feel like I just got a steal! THANK YOU

Thank you so much for the guard! I feel a lot better knowing I saved money and I’m taking care of my teeth.

I did not think the quality was going to be the same as my dentist makes but it is just as good if not better and they offer a two year warranty. Can’t beat it!
