Customer ratings & reviews

I grind my teeth at night and in the day and I've worn through many night guards. This is the best one I've ever had, and it has cost me the least. I've had it for several years now and it hasn't cracked, discolored or changed shape. I still have my wisdom teeth and Sentinel was able to get me a mouthguard that covered those as well. I like the night guard is clear, too. It's easy to leave in Efferdent all day, daily, and it looks obviously clean. It still looks the same as the day I got it and it has definitely saved my teeth from cracking. I also like that the 2mm one is still fairly thin and I can fit it in my mouth. It doesn't force my lips open at night. I've also been very happy with Sentinel's customer service. They replied to me quickly and made sure that I was happy with my product. I plan to order more from them again.

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.

I've ordered from other companies and these are simply the best. I've been with Sentinel since 2014 and they have stayed consistent and good.

Had previous trays from my dental office. They were uncomfortable on my gums becuase they were cut straight across. Sentinel did a good job fitting them to my teeth and I can tell they took the time to make sure there were no rough edges. Better than the ones I paid $300 for at my dentist. Haven't used the whitening gel yet but will update this review after 1 week.

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

I have used their mouth guards for over 5 years. High quality, they work as well as what you would get at the dentists. Customer service has been great, they have gone out of the way to make sure things are right. Highly recommencded

FABULOUS COMPANY!!!! GREAT COMMUNICATION!!!!! VERY POSITIVE EXPERIENCE!! A++

I’ve been using my Sentinel Mouthguard about 3 years now. They have good customer service. My first one got damaged while I was cleaning it and because it was still under warranty, they sent me a new one. Since they already had my mold, I didn’t have to go through the whole process again. I also used other mouthguards from retail stores, but this one felt very natural especially when I woke up in the mornings.

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