Perfect fit. You guys aced it. I was hesitant to take my own teeth impression but the process was easier than expected. I love my night guard and you've earned yourself a new fan. Nice job!

BEST NIGHT GUARD EVER!! I have always hated wearing night guards but my teeth hurt so badly if I go any amount of time without wearing them. I have searched and tried many different types including the ones from the dentist, the cheapo ones from Walgreens and even the front bite ones. I was displeased with all of them. Then I found Sentinel. This soft guard is not big and bulky yet it feels protective and so comfortable. As long as I'm grinding my teeth, Sentinel will be my go-to.

I bought this on Amazon and I'm so impressed by this company. My teeth impression kit was delivered within 1 day (granted I do have Amazon Prime). I took the impression, mailed it off and just a few days later, I received my custom made night guard. High quality product, fits like a glove and FAST DELIVERY. I would highly recommend Sentinel Mouthguards.

My mouth guard was delivered last week. I've been wearing it every night and my morning headaches and sore jaw are gone! I'm amazed out how easy it has been to get used to sleeping with it in every night. I used to wear a cheap one from CVS and I dreaded putting it in. The custom molding makes all the difference. Anyway, just wanted to say THANK YOU!

We have used this product for several years and I can attest the consistency and quality. They're hundreds of dollars less than my dentist and when I showed him my guard he was impressed with it! My wife has had hers for years now and it's still holding up. Truly a great product.

LOVE THE FEEL OF THIS NIGHT GUARD! Received this a few months ago and waited to write a review. The night guard is well-made and much more comfortable than I anticipated. I wore the cheapy boil & bites before this and what a difference! I'll never go back! My jaw feels great and if I don't wear it, I notice it immediately the next day. Great job!

Fast delivery and my new mouth guard fits like a dream! I'm sleeping through the night with it (something I could never seem to do with my other ones) and waking up without headaches and jaw pain. Can't thank you enough! Terrific service!

You have been one of the best customer service experiences I have had. And your products are amazing. The whole user / client / customer experience is incredible. I’m sorry my situation didn’t work out. But I am glad my girlfriend will be able to continue to support and use your services. All the best to you!

Truly great service at a great price! Well packaged box with clear instructions for taking my teeth impression. The mouth guard arrived about a week after I sent my impression off. Looks and fits extremely well. Couldn’t be more pleased. How do I upload a picture? Thanks, Marie

Better than my dentist's guard! The process was easy, customer service was great and when I messed up my impression (and used the extra putty they provided), they still sent me another kit for free! I got the medium thick guard for moderate teeth grinding and my teeth feel protected, Very comfortable, well-made night guard!
