Customer ratings & reviews

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!

I've played Hockey since I was little and have always hated buying mouth guards. They;re uncomfortable and I get yelled at for not having it hang out of my mouth. This is the first guard that has actually fit correctly. There is nothing that comes close to this fit and it's impossible to have this one hang out of my mouth because I have to physically remove it by popping it off of my back teeth. No comparison. 5 stars and highly recommended!
