Customer ratings & reviews

I have worn night-guards for over 20 years now, most made by my local dentist. These cost less than 1/4th the price, and are just as good a quality. The fit has been wonderful and I am going to order another pair.

Customer Service is A++. I have worn almost every single night for the past 3 years, and the product is still going strong.

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.

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
