Customer ratings & reviews

I am just writing to thank you for all the work you did to get me a mouth guard that fits comfortably. Sentinel mouthguard has great customer service. I had some problems with the original fit of my mouthguard, and they helped me return it 3 times and sent me a new impression packet. I am now completely satisfied with the fit. I would recommend them to anybody. Real value for the money! Thanks, Leah Morris

I highly recommend this mouth guard company. Their customer support is wonderful. I messed up my dental impression twice and they were very thorough in explaining where I went wrong. On the 3rd attempt I got it right. My night guard was a little too tight initially so I sent it in for an adjustment. Turnaround time was very fast. Overall, I'm extremely pleased with my night guard and the experience as a whole!

I really like working with sentinel, they're fast friendly and follow up well. Any problems are cleared up with a no hassle approach. They make it easy when my dog chews my night guard! It's not funny, but it's funny cause it's true.

My husband and I bought 4 guards from sentinel just so we would have a backup since we like to travel. So I should be able to write 4 different reviews right?? All of our night guards fit great. We are very happy with our whole experience with the company and recommended them to all of our friends. If you're sitting there reading these reviews not sure to make the buy, rest assured this company is the real deal. We are real people who are now customers for life!

My dentist always made a big deal of adjusting my night guard so I was really worried about this one needing adjustments but I did not need anything at all. It feel great & snaps into place. Makes me think my dentist was doing a bit of "rousing the stone". Happy customer!

Worth every cent! My teeth and jaw feel so much better. Thank you!

Awesome communication. The mouthguard fits perfectly. Very comfortable. If there is a problem they get right on it. Couldn't ask for a better company to purchase from and the mouthguard is very affordable. I love Sentinel Mouthguards.You guys are awesome.

Excellent service! It has helped my jaw pain out tremendously. Much appreciated -Devon

A++++ SERVICE IS REMARKABLE! I HAVE RECOMMENDED YOU GUYS TO SO MANY PEOPLE! I JUST LOVE YOUR PRODUCTS> THANK YOU!!

I have been grinding my teeth at night for many years but had put off buying a night guard because of the high price my dentist charged for one. Back in 2015, I read rave reviews about Sentinel and decided to give the 2mm Sentinel Hard Dental Night Guard a try. The guard has worn a bit in some spots, but it is still totally usable and going strong more than 3 years later! I couldn't be happier. Thanks Sentinel!
