Customer ratings & reviews

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!!

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

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

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!

Glad I gave them a try! It didn't work out for me at first because right after I placed my order, my tooth broke and I needed a new crown. I called them and they told me I could hang on to the teeth impression kit until my dental work was completed. Well, it took me 1 year to save up for the crown. I called and they still honored my order. That's what I call great customer care! I received my new night guard and it fits beautifully. Happy customer!

I have been having serious grinding issues since being locked at home- my teeth and surrounding areas including my jaw were in real pain every single day. My jaw would painfully pop when I ate anything or dared to open my mouth too wide- I was miserable. Bought way too many over the counter guards with minimal results. First use of the Sentinel guard and immediately noticed less pain- the very first night. I've stuck with it and all of my symptoms are near gone. This product works! I won't be going back to Walgreens. I'm sticking with quality.
