Customer ratings & reviews

Can’t believe I’m writing a product review for a mouth guard but it’s that good. This is the most comfortable mouth guard I’ve ever worn. I'm impressed by this brand. Responsive, quick and high quality!

This was better thank I expected. I admit I was a little frustrated with the putty impression process. I was so nervous to take my teeth impression and of course I didn't do it correctly the first time. I finally settled down and got a nice impression of my teeth. It was easier than I thought it would be. The Sentinel lab crew took care to make my guard fit perfectly from the impressions I sent. I'm happy with the final product and will reorder again when the time comes.

Replacement for an old one I lost or grew legs! This company is consistently awesome. I ordered years ago. Loved my last guard and was a bit worried that things may have changed over the years and the quality might not be the same. But like a good wine, these guys seem to get better with age. Thank you again Sentinel! Cheers!

Thank you Sentinel! Affordable prices, great fit and great customer service. My husband and I thank ya much!

Excellent! I use it every night. Now I can't be without it. 5 stars!!

BEST MOUTH GUARD I HAVE FOUND! This is a 5 star product, way cheaper than the dentist and fits perfect.

Great price for a great product This is a fantastic find for a great price.

I researched a lot of other companies and they didn't require the upper and lower teeth impressions. I like that they make sure the bite is correct. I was skeptical because it's so much cheaper than the dentist but I got my guard and waited to weigh in. The guard fits perfect and I've been sleeping soundly for several weeks now. This is the real deal. Thank you for existing Sentinel. You're a tooth saver!

More comfortable than I expected! Extremely happy! *****

This is the only brand I trust. I've been a Sentinel customer for 10 years. Their customer service is great. They're consistent and I love their night guards. I have a no-show day guard that I wear during the day and the extreme durability guard at night. Nothing less than a positive experience for me. 5 stars!
