Customer ratings & reviews

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.

Sentinel does what they say they are going to do with excellence. I have used other online companies in the past with okay results but Sentinel seems to genuinely care. Clear, easy, concise process. Would also like to mention that their customer service is great! They are kind and professional. Highly recommend. Highly trust.

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.

No complaints! I was skeptical and nervous to take my dental impression but customer service was very helpful. They answered my questions and eased my concerns. My mouth guard fits well and has held up to my intense teeth grinding. Thank you!!

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!

I used this kit for a week before I left for a wedding and it worked GREAT! I was telling my friends about it at the wedding as well, Hopefully I got you some customers! THANKS!

A common question I am asked from other fighters is if the mouth guards are breathable and if they're thin or bulky. The answer is definitely yes they are extremely easy to breath and talk with, and you can get your mouth guard made as thick or thin as you want. I prefer the 2mm thickness. It's not bulky at all and I still feel protected.
