Customer ratings & reviews

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

Excellent product. The night guard was a little tight the first couple of nights but now it feels really great. No more headaches from grinding teeth all night.

Excellent quality and superior customer service. They fit better than my dentists!

Just wanted to let you know I received the 2mm night guard and it fits perfectly! Once again, I am very happy and satisfied with your service and Sentinel. Happy New Year and thanks again for everything!

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.

Came on time as promised. Love it!!

Very fast shipping and excellent customer service. Would recommend.

THE 1mm THICKNESS IS PERFECT FOR DAY USE!! Chose this guard because I needed a thin appliance to wear during the day. Asked for the guard to be made like my old dental retainer. I sent a picture in for reference via email and received a very nice, very thin retainer-like daytime guard. It is perfect. No one even knows I'm wearing it. I do take it out while I'm eating. My jaw pain from clenching has drastically reduced. Think I may order a thicker night guard for nighttime clenching next but this one has definitely helped my symptoms. Thank you!
