Customer ratings & reviews

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.

Outstanding product and service! Sentinel's customer service is unparalleled!The care and individual service I received is worth writing a review for. I greatly appreciate the excellent customer service and their willingness to go above and beyond.

I purchased a 1 mm bottom guard. The process was easy to take an impression. The guard itself actually fit very well and got used to it within a few nights. I tried others but they were way too bulky, not allowing me to sleep with my mouth closed. I have had this guard for well over a year and just now starting to see signs of wear. I will be ordering another.

I clench my teeth a lot at work, and I've tried many night guards of all types. They never form well and they're bulky. This night guard is nice. I can close my mouth, talk, drink water, etc. It's the best of its kind I've used. I would highly recommend it.

It's like the dentist ones. Pleased with the fit. I ordered the teeth whitening too and will review the whitening once results are in.

Where do I start? This mouthguard is by far the best I've ever had. Very professional process from start to finish. It is perfect. I did not think I would be able to wear a mouthguard comfortably throughout the entire night. I've never had such a perfect fitting, comfortable mouthguard.

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

Better quality than what I got at my dental office. I would definitely recommend Sentinel Mouthguards to family and friends. I am very pleased with the fit of the product and customer service.

Great quality and great company! I was so happy when my retainers finally arrived to my door! I wasn't sure if my impressions were going to be good enough so I emailed a couple of pictures of the impressions and they said it was best to send new impression kits to me to retake them. I got it right the second time and received my retainers yesterday! The fit is perfect. Thank you!
