Customer ratings & reviews

This is a great service. The response time was excellent, the process easy, and the product just as advertised.

Got my new guard in the mail today! Flawless fit! I'm actually looking forward to sleeping with it in tonight! Thanks Sentinel Team! A++++

I LOVE Sentinel mouth guards! I've bought from this company for 5 years - 1mm, 2mm, and 3mm (I'm a heavy grinder) and I've always had great service and quality products delivered to my door. For years dentist(s) wanted to charge me hundreds of dollars for just one mouth guard (ridiculous!) and I told them no way and ordered from Sentinel! Don't let dentists talk you into super expensive mouth guards - Sentinel can make them for you at a fraction of the cost!

I purchased a hard acrylic mouthguard from Sentinel in 2015 and it still looks great. It fits better than a previous one that a dentist gave me. I sincerely recommend this company for their excellent service and for their low costs. Thank you, Sentinel!

I've had my guard for a couple of years and it still works for me.... I am a HEAVY grinder!!! Super comfortable, has held it's shape perfectly, perfect fit. I will be ordering another one soon, just because I want to have a back up. Amazing product, for real. Incredible price, incredible product.

This is the best nightguard I have ever owned--better than those I paid $500+ for at the dentist's. It's thinner than I am used to which initially concerned me, but the material is extremely strong and durable, so the thinness ends up being a positive because it makes the nightguard less obtrusive and more comfortable.

Received my Mouth guard fits Perfect!!! -Warren White

Thankyou. Your product is awesome. This is my second mouthguard (I lost the first ) and I have recommended you to Dentists and Doctors. It is so comfortable and unobtrusive. Regards Tanya

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.

Have been using my 1st order for almost a year and they are great. Quality is the same if not better than the ones I got from the dentist!
