Customer ratings & reviews

I have been wearing night guards for 30 years and this is by far the most comfortable one I've ever worn. The fitting kit was easy enough to manage. Turnaround was quick! Amazing! Thank you so much.

Get one!! You will be impressed with this company! For the past few years, I've been experiencing jaw clenching during my sleep. Although it may have started due to stress, even during periods where I felt calm, it continued to persist. The issue was further aggravated by a cheap night guard that I purchased for less than $20. I did some online research and decided to give Sentinel a try. Their customer service is excellent. Very helpful with the molding process and my night guard fits great! I'm entirely pleased and would recommend this service to anyone. A+

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.
