Customer ratings & reviews

Bought this for my daughter. She said on a scale of 1 to 10 it is a 10 in comfort! She's been a longtime teeth grinder. The dentist said she would grow out of it as a child but here she is at 18 still doing it. We have tried the walmart guards and they never were comfortable enough for her to wear during sleep. Truly the best! We looked around and decided on Sentinel. Glad we did. Thank you!

Well worth it!! Easy to follow directions. Great for both beginners and experienced dental night guard wearers. Only would have loved a faster turnaround time but I'm pleased with the final product. Now I can't wait until my nighttime grinding is cured so that I can quit sleeping with plastic in my mouth!!

I am a horrible nighttime teeth grinder and clencher. I have managed to chew threw so many of these things. I am very happy with this guard. I love that the company keeps impressions on file for 2 years because I don't enjoy taking my dental impressions and I may need another soon!

Not bulky. The fit is very nice. I have used this for 3 nights so far and I think this may be the best purchase I've ever made. I highly recommend this product for anyone who experiences pain from teeth grinding.

My mouth is on the small side. I was worried the guard wouldn't work for my small mouth. I contacted customer service and they said to just request smaller trays for the impression process. One of the tray sizes was perfect. I absolutely recommend this product. Aside from the guard fitting perfectly and serving its purpose, the customer service team is the real gem. They are responsive and very knowledgeable. 5 Stars

We are huge fans! My mother needed a few attempts with the impressions, as it was difficult with her arthritic hands, and they were so patient and lovely about it. After a few back-and-forths we now have a PERFECT fit! We also required a custom size of 1.5mm for dual-laminate, versus the standard 2mm, so don't hesitate to ask if you think 2mm might be too thick. Ashely was such a pleasure to work with, and a very fast response time.

The process of creating your own mold is so simple and easy to execute at home. Unfortunately, my dog ate my first guard but ordering a replacement has been a breeze. Thanks for an affordable and quality product!!

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

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

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.
