Customer ratings & reviews

Love the look and feel! I chose white. It’s thin and if you didn’t know any better you’d barely be able to tell I have one in. I got the thinnest one because I have a bad gag reflex. Impression putty process was easy. Will use again in the future!

I need it as a lower mouthguard to protect from biting my lip during sleep. I tried a over-the-counter solution which was worthless. Found sentinel on the Internet. Was impressed with a customer service representative, Ashley, who took me through the process and inspired confidence in the company. After receiving the mouthguard, I wanted a slightly deeper impression. Spoke with Ashley again and she arranged to have a new guard shipped with no questions asked and no additional cost. The new guard fits perfectly. I would recommend this company without reservation. Thanks Ashley!

My review is consistent with all of these other reviews! Very easy process with clear instructions. Kudos to these guys for saving me so much money!

Totally worth it! service is top-notch and the fit is spectacular!

Love the free shipping and these are the best prices on the internet. I've been through other companies and you guys ROCK!

This is a lifesaver for me! I was cracking my teeth and having horrible jaw pain. The store bought guards weren't cutting it and the dental office price is unbelievably high. I chose Sentinel Mouthguards because of the price point and the 1 year warranty. So glad I did. Absolutely terrific company with a great product!

I bought this night guard for my son who grinds his teeth. We unsuccessfully attempted the first mold but Sentinel sent another kit out right away. So happy I could get this mouthguard at an affordable price. My dentist wanted to charge a small fortune! Thanks Ashley & the rest of the staff. You guys are great!

EXCELLENT!! I didn't get my impressions right the first time and I used up the extra putty. They sent me another kit free of charge! I sent in photos and they were accepted. Company has great customer care and the retainers fit like a dream!

Perfect fit. As soon as I tried it in I knew I made the right choice. Worth the money. Thank you!

Sentinel is really great! The process was easy, the shipping was really quick. Upon receiving my guard, I used it for two nights and it was slightly uncomfortable in one area of my mouth. I realized it was because I probably didn't do the imprint process correctly. I contacted Sentinel, they adjusted the guard and sent me a brand new one. This one is perfectly comfortable and allows me to sleep well at night. No more grinding my teeth and I feel healthier already. Thank you to the team at Sentinel for hooking if up!
