Customer ratings & reviews

Thanks to the talents of the Sentinel team, a very hard, stable & durable night guard was made for my teeth so that I can sleep without having to wake up with the facial pain & headaches I was experiencing nightly. I feel good knowing my teeth are protected & at an affordable price. Muchas gracias for your generosity. *Angelina

Love this service. They're honest and upfront about what they offer. I had a few questions in the beginning. Ashley and the rest of the staff were prompt and helpful. I got a great night guard for a portion of what my dentist was charging. Very thankful for this service. Kind regards, Matt

The team at Sentinel was easy to work with and helped me with choosing which night guard was right for me promptly & painlessly. I've worked with them before about two years ago, and that was great too! Highly recommended.

I love this mouth guard because it is perfectly fit to my teeth. It feels great & not bulky at all. Love your service guys!

I'd been using the standard night guard (purchased at CVS) but had trouble sleeping throughout the night. The store bought guard was soft & loose fitted. I was considering a high dollar night guard from my dentist when I read a thread on Reddit about Sentinel and the DIY impression system. So, I bought a kit and gave it a try using the putty and trays provided. Easy. Took a great mold of my teeth and got a great fitting, comfortable night guard. Since then, my wife and sister have both bought their own. Lucky to have stumbled across such a money saving alternative.

Fantastic experience with a company that is on their game. Smooth, quick process. Even got a couple of night guard cleaning tablets in my package. Would highly recommend!

I really like these night guards. I do not like soft floppy guards. They always seem to move around in the mouth and stretch out over time. These are hard and actually snap on to my teeth. The edges are smooth and not rough to the tongue or gums. This is my second guard from Sentinel and I ordered the 2mm. I would order more.

My nighttime grinding has not stopped ( I guess until there's a cure this is as good as it gets) but I am at least grinding away on some durable material instead of my teeth. I have noticed my jaw & facial pain has stopped & I am grateful for the two year warranty on these.

No complaints here. Price was righteous and works well even a year later. Looks professional/high quality and beats dental guards you'd pick up from a retailer like Walmart & CVS. Seriously, why buy junk like that when you can wait three weeks and get something fantastic that is fitted to your teeth and actually works!

Thank you for your responsiveness and great service. Greatly appreciated:) -M. Massey
