The customer service of this company is wonderful. They’re a small, family owned business and I love that everything is made right here in the USA! I have a gluten allergy and learned that my dentist was using a Chinese lab to make his night guards and couldn’t verify the materials in it! I was able to order a gluten free mouth guard from Sentinel that fits perfectly and I couldn’t be happier! Excellent product and service!!
Nadar
I love my first night guard. Had some dental work done so ordering my second! I suffer from TMJ and this guard I wear for my lower teeth. It helps greatly with my jaw pain. No more popping and clicking since I started using it. The Sentinel team is fast, courteous and the product does the job at a price way lower than my dentist. Amazing!
Gina Cameron
I love my mouthguard that I ordered last year in August and unfortunately I cracked the back piece where my molar grinds down on the guard.
Sentinel sent me a free replacement. I received it so quickly and it fits perfectly. Thank you for taking care of your customers!

This product is the real deal!
I’m writing this review because I recently took my custom night guard that I received back in April to my dentist. I expected him to tell me that it was crap and that I needed to purchase a night guard through his office. Instead he said it was a very well made, great fitting guard. I’m very pleased with the high quality, commitment to safe products and the price! Keep up the good work!
ROXANNE
I LOVE the fit of this night guard! I had tried one from my dentist at a cost of $600. Wore it for 4 nights and threw it out. I tried the store bought guards with no luck. Figured I was out of options until I came across your website. Customer service was great at answering my questions and the guard fits FAR better than the others.

The guard I ordered a year ago is still good but I had some fillings on my back molars and that changed my bite so I’m reordering. Great product 😀

You guys have the best customer service. Hands down! I ordered from your company three years ago and just placed a second order. I can’t wait to receive my newest guard. Top notch everything!!
