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!!!

I originally ordered the hard night guard but found it to put too much pressure on my teeth. I contacted customer service and they made me a soft guard as part of my satisfaction guarantee. They even refunded me the price difference as the soft guard is a little less than the hard. Their customer service is excellent and they have gained a customer for life. Thank you!!

Don't hesitate to order from this company. They're the absolute best. I've been a customer for over 7 years now. Long time returning customer and always the same level of consistently excellent service. -Cindy

I love love love this night guard and the convenience of this service. The first thing I do in the morning is scrub it with some liquid soap, rinse it, dry it and put it right back in its case next to my bed. This way, it's ready for me at night and it stays clean and clear. I had one years ago that I didn't take care of and it turned a disgusting yellow. Never again! This option is far cheaper than my dentist and the quality is superior. I will definitely buy this again!

Just wanted to say thank you for my great fitting mouth guard! I'm glad I chose the thicker one. I was worried it was going to be too bulky but it feels comfortable and I'm sleeping through the night.

I couldn't be happier with this product. Beautifully made and high quality. Super convenient service. I HIGHLY recommend.

I've ordered from various vendors online and Sentinel is by far the best. My mouth guard fits like a glove. I sleep with it every night. I recommend you guys over and over. Thank you!

Very happy with the level of customer service and the high quality product. If you're on the fence about it, it's definitely worth the money.

Very good night guard at a decent price. I tried the ones you boil & bite but it was so bulky and made me gag. These are custom made from an impression from your teeth and there is a HUGE difference. When you do the impression, make sure you do it in front of a mirror and use the bigger sized tray. Not the smaller one. I made a mistake the first time but they include an extra set of putty for a retry. Overall, great service from start to finish!
