Customer ratings & reviews

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!!

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!

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!

Great craftsmanship. Great fit. Overall 5 stars

Just want you to know that I received my night guard and the fit is perfect! High quality product with great service! Will be using you again in the future!

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!

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 :D

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!!

Best purchase I ever made 3 years ago and here I am again to order a new one! You guys are great!
