Customer ratings & reviews

BUY THIS MOUTH GUARD WITHOUT ANY HESITATION! I did a LOT of research before choosing Sentinel. One thing I found that they offer is the 1 year warranty. I emailed to verify this and if my night guard cracks or wears through within 1 year, they will replace it up to 3 times! That's a big plus for me because I'm a pretty heavy teeth grinder. The guard fits flawlessly. Service was quick and top notch! Teeth impression kit was easy and straight forward and they were patient in answering my many questions. I feel like I did the research for you guys. You will not regret choosing this company to make your custom mouth guard!

Impressed! Very good quality and the fit is exceptional. After many expensive teeth repairs, I have learned my lesson! Wear your night guard! This is the best guard in terms of fit and quality I have every had. This is the company I recommend buying from.

Two things: I LOVE this night guard and it was the process was much faster than I had expected. As soon as I took it out of the package I knew it was high quality. The fit is better than any other night guard I've worn. Will definitely be using this service again.

This night guard is awesome! My teeth fit easily and comfortably inside the guard. I waited to review to see how long it would last. Usually by now the my old night guards that I've gotten in the past from my dentist start to crack or wear down but this one is still holding strong! I do take very good care of it and keep it in its case by my night stand. I clean mine once every week with Efferdent denture cleaning solution but I think that is a personal preference. I don't want it to yellow!

Thoroughly surprised! I'm very pleased with my purchase. Great quality at a great price!

I have been wearing night guards for over 10 years. All those years paying $600 every time I wore one out and I never thought to check online. The quality and fit are just as good as my dentist. I'll never pay those kind of prices again. You have my business for life! <3 Rachel

Took the quiz to find out which night guard I should get and it said a hard guard. I was skeptical that the hard one wouldn't feel comfortable. First few nights took some getting used to but now I love it. The whole process was smooth, shipping was fast and easy and the night guard fits like a glove. Here's a tip: When you take your dental impression, make sure your teeth are centered in the tray and sink your teeth into the putty all the way while holding still. Don't move around. After 2 minutes or so, the putty should be hard and you can remove the tray. Make sure your impression looks correct before sending it in or they'll have to send you a new kit. I sent in a picture of my impression and they were quick to respond. I hope this review helps someone!

This is the best! I've tried many guards over many years of suffering from TMJ, and none worked or were comfortable to wear. This guard is extremely comfortable and really does help with relieving my jaw pain and protecting the teeth from grinding. Customer service team is very nice and fast. Excellent all around experience!

HIGH QUALITY AND HIGHEST LEVEL OF SERVICE ***** I 100% recommend this dental night guard delivery service. They remove all of the excess plastic for a slim fit. Not at all bulky in the mouth and crafted with care. Thank you Sentinel team!

My teeth and jaw were so bad off before I started using the Sentinel guard. I have a 2mm upper. It's a lifesaver! I can't sleep without it now! 5 stars and I'd give 10 if I could!
