    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.

    Love my Mouth Guard

    I do wear this at night, and I feel like I’m doing something very good for myself when I do!

    No complaints

    It fits, it works, and Sentinal had to resent the imprint package to me twice because I screwed up. I appreciate that.

    Functional, Comfortable, and Invisible

    I have developed a habit of grinding my teeth during the day. This new mouthguard fits in such a way that it both prevents grinding and is completely invisible. I can speak and drink comfortably while it is in. I highly recommend it, especially for daytime grinders like me.
