Customer ratings & reviews

I received a very expensive night guard from my dentist and it was so bulky I couldn't close my mouth let alone sleep with it in! I called Sentinel customer service, spoke with a very nice lady and she suggested this guard type. I went with the "thicker" option and was assured that it would not be bulky. She was right! It's perfect for my mouth. It protects my teeth well and my jaw says THANK YOU! For the impression process, I received a kit in the mail quickly after ordering. It came with an extra set of putty and I didn end up needing it bc my first impression was too shallow in the back teeth. I sent a picture in and again the communication was fast. The reply email stated the reason why it wouldn't be acceptable and came with a reference picture of a great teeth impression plus additional tips. I retook my impression and it came out much better the second time around. The shipping of the night guard was quick. I received an email when it shipped and it didn't take the lab long to make it at all. The night guard is flexible and clear. It appears to be high quality material and has felt comfortable in my mouth right from the beginning. My experience has been great and I recommend this company without hesitation. A+++

Just writing a review for you guys which I rarely do but you deserve it. Thank you for being so responsive to my 50 questions. The mouth guard fits very well and I felt supported through the process. Thank you :) If you're shopping around, don't look any further. Sentinel Mouthguards is #1!

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!
