Customer ratings & reviews

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!

Best teeth guard I've ever worn! Slim design, light and fits like a glove! The one from my dentist didn't compare to this one. Comes with a nice storage case as well. Thanks guys for an amazing product!

Wow! Just terrific customer experience all around. I received my night guard today and if fits perfectly. Thank you!!

Taking the mold of my teeth was a lot easier than I expected. The impression kit came to my house within just a few days of ordering. I watched the Youtube video and looked over the instructions that came in the box. Easy and straight forward. This process ended up being SO much less expensive than the dentist and I love how it fits and feels. I wear this while I'm lifting weights too. An extra perk!
