    Comfortable and invisible!

    I have been wearing a Sentinel Night Mouth Guard for many years and it helped relieved headaches and wearing down of my teeth due to clenching. I have recently found that I am also clenching during the day, so I decided to try a mouth guard that I could wear during the day. I just received my new No-Show Day Mouth Guard and it is so comfortable. It is almost invisible in my mouth so I wear it during the day while at home. Thanks Sentinel for providing such exceptional products and customer service.

    So much better than boil and bite

    Those store-bought guards feel like you’ve got a hockey puck in your mouth—can’t even get my lips to close over them. But the sentinel guard I got is thin and custom fit. Doesn’t keep me awake and protects my teeth. Highly recommend.

    Quick and Easy

    Such an easy way to clean my mouthguard every morning. I get it set up the night before, throw the mouthguard in before I get in the shower and when I get out, it is cleaned and sanitized!
