Customer ratings & reviews

Aside from unbeatable comfort, the second best aspect of the Sentinel mouth guards is that you can customize them to any color you desire. You can have your name imprinted on them or your team name and colors. I still have my first mouth guard that I ordered from Sentinel in 2011 (just a plain dark blue) and just had a second one made in honor of my dad. I recommend you guys all the time. You're the best!

First, I do not like to buy things that I am not able to test before buying. We did buy these based on the most recent reviews on this product. I have had this dental guard for two weeks and it is GREAT! So much relief to find a superior product for way less than what my dental office was going to charge me.

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

I messed up badly with my order: I ordered a sports mouthguard instead of a nightguard, the wrong size as the plastic mold was too big to fit in my mouth, and I even messed up my print. Ashley from customer service was my saviour: she overnighted me a new mold, new putty, and when I received the nightguard, she even sent me the sport mouthguard replacement. Very high quality service. Praiseworthy!

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.

Great service. My night guard came in the mail quicker than I had hoped. It saved me a ton of time and headache (literally my headaches and facial aches are gone!). Thanks guys!

I reached out to Sentinel about my teeth grinding issues. The Livechat operator was very informative. Instead of trying to sell me on their more expensive services, I was instead told that I was already in pretty good shape and did not need to spend the money on the more expensive mouthguard types. I received my Soft Dental Night Guard in the mail and I can't explain how nice it is to wear an appliance that is custom made for you vs the store bought kind. Very happy customer! Thanks!

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.
