Customer ratings & reviews

Got a different brand the first time I ordered online and the mouth guard was okay. Should have went with this brand to begin with. Noticeable difference in quality and fit. Turn around time was fast too!

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!!!

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

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!

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.
