Wasn't sure whether I should go with an upper or lower guard. I chose the upper and when I got it I just couldn't get used to it. I've never had to sleep with anything in my mouth and I found myself taking it out at night. I emailed the Sentinel team and told them my dilemma. They suggested I try a lower instead and voila! Feels so much better. I was most impressed that they really did work to my satisfaction and did it without sneaking in extra charges or hidden fees. Honest and good company. Thanks.

I've been paying $600 for a night guard (and replacements) for years through my dentist. I feel like I just got a steal! THANK YOU

Thank you so much Sentinel! You saved me money and from a lot of frustration! Fits perfect!

Got my night guard about a week ago and have been sleeping with it every night. I was going to send an email saying thanks but decided to write it here for everyone to see. Not knowing that I could buy online, I had a dentist make one for me years back and I wore it because I paid so much for it but it was never comfortable. I did a lot of research on this dual laminated type and decided it has to be more comfortable than the one I had and I was right. It's been great so far and I just wanted to share my quick story. Thanks!

Thank you so much for the guard! I feel a lot better knowing I saved money and I'm taking care of my teeth.

Sentinel mouthguards are the best! Almost our entire team wears them. Keep kicking Arse!

Same one my dentist made for me. Absolutely no difference at all except the cost. Such a relief!

I did not think the quality was going to be the same as my dentist makes but it is just as good if not better and they offer a two year warranty. Can't beat it!

Honestly I wasn't too sure about buying a night guard online so I called the company to test the waters a little bit. I can't remember the name of the guy I spoke to, but I could tell it was a real company and he made me feel a lot more comfortable about buying online. He didn't try to up sell me or anything shady, was just friendly and came across very down to earth. I like that in a company, and I def like saving money.

By far, the most comfortable night guards on the market. These guys take pride in their work and will work with you to your absolute satisfaction. -Lauren Moudry, Baton Rouge La. Long term sufferer of Bruxism
