Customer ratings & reviews

Love the glow in the dark case! Opened my mail in a dim lit room and the little box was glowing back at me! Perfect fit. Terrific experience!!

AMAZING TO WEAR NIGHT AND DAY!! Great product! I definitely recommend this to anyone looking for a high quality retainer without the high cost. Easy to wear. I wear this pretty much all the time except when I'm eating or drinking. I want another one for travel!

Insurance wouldn't cover my nightguard through my dentist. Read an article online and found Sentinel through the article. So happy I did! I paid a fraction of what my dentist wanted to charge me. Happy customer!

Worth every penny! I do all my shopping online already as it is so why not a night guard. Thank you for the great nightguard

I've found the company I was looking for! I went through my dentist at first and it was a horrible experience. I have had bruxism for years due to stress and the mouthguard he made me cut my gums. He tried to "fix" it but it was still awful. The difference between this mouthguard and the one I received from him is incredible. The material quality, the fit, everything is sooo much better. Thank you for offering this to people and doing a BETTER JOB THAN THE DENTIST!

Top notch service and outstanding, high quality product! I love your night guards and they have saved my life! I was spending so much unnecessary money at the dental office and then when I couldn't afford that, I went to the drugstore options. Ugh! So happy that you have an affordable option that LASTS! Love you guys!

Spoke with Alexandra and she was very helpful and recommend that a ask for some extra putty!!

Prompt shipping, fast turn around time and high quality product. Can't beat it!

Customer service is out of this world good! I decided to purchase this guard after my dog chewed my old one. I had several questions about the process. Customer service was excellent! My kit arrived fast and the molding process was simple. The mouthguard I received is very well made and fits extremely well. All in all, my experience was a very positive one and I will recommend to family and friends.

No better mouth guard out there! This is it. This company has it all. Excellent customer service, informative, fast, affordable and they make a great product. I tell all my co-workers, friends and family about Sentinel Mouthguards. I've been with them since 2012 and I'll continue to be a lifelong customer. Great work guys!
