Customer ratings & reviews

Love that this company lets you choose your own thickness. I have the worst gag reflex and needed a very thin nightguard. I'm pretty sure this is the only online company that offers the thickness choices. Happy customer!

1/2 the price of my dentist and just as good!

Didn't realize I would have to make a mold and send it back in to the company but am excited to see how it works. Kit seriously came within 2 days. Eagerly awaiting the final product to come back. Excellent company to work with!!!

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.
