Customer ratings & reviews

Love this company!! I have ordered 2 guards from Sentinel plus a teeth whitening kit. Everything I've received has fit perfectly, it's high quality and the service is fast and friendly. Sentinel has my business for years to come. Thank you for doing things right!

The absolute best night guard ever! So glad I found this here. My dentist was asking for $600. Fit is true to my mouth and my jaw pain is gone!

Half the cost then my dentist is selling for the exact same product and same results.

The communication was excellent, and the turnaround time was very fast. I would highly recommend this company for anyone looking for a reliable night guard provider.

The process was easy and straightforward, and customer service was patient and helpful in answering any questions. I received my mouthguard and the fit is flawless. Excellent experience!

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!
