PERFECT FOR SENSITIVE TEETH! I don't write reviews very often but my hunt for a teeth whitening product that doesn't make my teeth feel like all the nerve endings are firing at the same time has ended! I don't leave the gel on very long because I have super sensitive teeth but it still has whitened my teeth very well. I still have plenty of gel left over to re-whiten when they start to yellow again too. The professional quality trays fit snug on my teeth. I'm very pleased with the whole experience.

THE MOST COMFORTABLE! Initially, the upper retainer fit great but my lower was off. Contacted customer service and was promptly sent a new kit. They remade my lower retainer quickly and it fits perfect! I saved a lot of money and the quality is excellent.

This is the best mouth guard I've found for daytime use. I clench my teeth horribly during the day. I use this while I'm at the gym and in the office. This is a great article they sent me about how to take care of it and keep it from turning yellow. I've had many many night guards before and if you don't take care of them properly they will turn a nasty yellow! Thank you Sentinel team. You have a customer for life!

EXCELLENT QUALITY, GREAT FUNCTIONALITY!! I chose this company because I can customize the thickness. I only wear this for weightlifting so I didn't want a bulky mouth guard..very happy with purchase.

Beautifully crafted and it does the job!! This guard is awesome.It does great job of keeping my teeth from wreaking havoc on each other. And for the price, it is just what you need.

Sentinel is the best!! I'll save you from a lot of wasted time. I've been a teeth grinder for many years. My jaw is a wreck. I've had dentist made guards, store bought guards, and I've tried other online labs. Sentinel is the ONLY company that has been able to help relieve my jaw pain. The Sentinel guards fits. it's comfortable and durable. This is a high quality service and the best I've found. Save yourself time and money and go with Sentinel!!!

This product is the real deal! I'm writing this review because I recently took my custom night guard that I received back in April to my dentist. I expected him to tell me that it was crap and that I needed to purchase a night guard through his office. Instead he said it was a very well made, great fitting guard. I'm very pleased with the high quality, commitment to safe products and the price! Keep up the good work!

My nocturnal tongue biting issue had gotten so severe that I was in pain constantly. I tried ointments and the cheap night guards you can get at drugstores. None of it worked. A friend recommended this company to me. I messed up my teeth impressions the first time but I was sent new materials and an email explaining what I had done incorrectly. I was able to do my molds correctly the 2nd time. When I did receive my new guards I was impressed by the quality and care of crafting. I noticed a difference the very next morning in my pain level. Within a few days, my tongue had healed. I wear these religiously and want to share my experience here. Great for severe tongue biters!

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

I LOVE the fit of this night guard! I had tried one from my dentist at a cost of $600. Wore it for 4 nights and threw it out. I tried the store bought guards with no luck. Figured I was out of options until I came across your website. Customer service was great at answering my questions and the guard fits FAR better than the others.
