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.

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

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
