Customer ratings & reviews

Fantastic experience with Sentinel Mouthguards! From customer service to timeliness of the deliveries and receiving my night guard, everything was impressively smooth. I will be recommending this service to anyone who grinds their teeth. Thank you Sentinel!

Great customer service is why I continue to return every 2 years for new guards that I have chewed through.

VERY IMPRESSED! AFFORDABLE AND GREAT FIT! This is a solid product with great customer service. I've worn the OTC guards before and never could sleep a whole night with one in. My experience is the opposite with this custom fit night guard. I can barely tell I'm wearing it and my jaw feels so much better!! My experience has been excellent. I wish I had gotten this sooner.

Great night guard! Exactly what I wanted. Fast and easy process. The fit is great! I'm very happy with my purchase.

Item arrived promptly and the fit is great. This is my favorite grinding guard thus far. My teeth are nice and straight but flat from years of grinding and just aging. I was using my old Invisilign tray but it wasn't cutting it so I decided to with Sentinel. I have nothing but compliments to say. I recommend this item to anyone that grinds their teeth. Life saver and worth the investment!

Love Sentinel Mouthguard products. This one has protected my teeth longer than the one my dentist made me. -CK

WOWZA! These mouthguards put all other mouthguards to shame! How can they fit so good, yet so inexpensive compared to my dentist? And comes with a 1 year warranty! Best night guard I've ever had. Literally obsessed with how good this fits. <3

As always, Sentinel Mouthguards has knocked it out of the park yet again. Always great service, quick turnaround time and the fit of my night guard is impeccable. Their work is excellent. I greatly appreciate the attention to detail and the friendly experience.

BUY THIS MOUTH GUARD WITHOUT ANY HESITATION! I did a LOT of research before choosing Sentinel. One thing I found that they offer is the 1 year warranty. I emailed to verify this and if my night guard cracks or wears through within 1 year, they will replace it up to 3 times! That's a big plus for me because I'm a pretty heavy teeth grinder. The guard fits flawlessly. Service was quick and top notch! Teeth impression kit was easy and straight forward and they were patient in answering my many questions. I feel like I did the research for you guys. You will not regret choosing this company to make your custom mouth guard!

Impressed! Very good quality and the fit is exceptional. After many expensive teeth repairs, I have learned my lesson! Wear your night guard! This is the best guard in terms of fit and quality I have every had. This is the company I recommend buying from.
