Customer ratings & reviews

I'm 30 years old and I take care of myself. I feel like I have low stress but for some reason I grind my teeth like crazy! My jaw pain became so severe I couldn't eat hard foods. I couldn't afford the dental office cost so I took to Sentinel and I'm so glad I did. My jaw pain is completely gone. I wear this soft guard during the day and a harder one at night. Definitely eliminates the daily grind!

My new Sentinel guard is perfect! It is so light and comfortable. I would definitely buy again!

They worked with me to get my impression right and didn't charge me for extra kits. I appreciate their commitment to their customers. I had an issue with my first guard and again they worked with me and remade the guard. The second one fit like a glove. They're a small business right now and I hope they don't grow and lose what makes them great.

My night guard fits perfect and is so comfortable! I’m glad I went with the 2mm thickness. Thank You!

SENTINEL NIGHT GUARDS ARE THE BEST!! The staff at Sentinel Mouthguards is nothing short of amazing!! I love that they offer different thicknesses. I tried the very thin one at first and it was too thin. They switched me to a thicker guard for free and followed up to see how I was doing with my new mouth guard. Fantastic experience and great product!

Excellent mouthguard. Does not bother me at night or slip out. Actually fits better than one I had made my dentist. Will definitely buy from Sentinel again.

The fit is wonderful. I was so impressed by the comfort of this night guard. It conforms to my mouth and after several months of wear, it still fits perfectly snug.

Ive had my mouthguard for about a year and a half now. Just had to use my warranty to get it replaced. Felt inclined to leave a review about my experience. Sentinel Mouthguard Co. stands by their replacement warranty. No questions asked, I simply attached a picture of my nightguard showing existing wear to an email to the company. Within 10 days I had my replacement. I don't know of any dental office that has a warranty like this. Exceptional customer service & product. Thank you Sentinel. Sincerely, Gabriel M.

Sentinel exceeded my expectations in every facet. Fast and helpful service! The mouth guard fits and works perfectly. I ordered the thickest one and have had it over 6 months. My family and I will continue to use this service for all of our mouth guard needs. Just ordered my son the sports guard for football!

Perfect fit and above all, Sentinel's customer service is excellent. I had an issue with shipping and it was immediately addressed.
