    Thank you

    The Tongue & Cheek Biting Relief Mouthguards are working flawlessly. Not a single biting episode since the very first night of wear. Took 1 night to get adjusted to the wearing of your guards. I should have purchased your mouthguards a longtime ago. I could have spared myself a lot of misery. Thanks for a superior product. Keep up the good work. 6 stars

    Durability Mouth Guard

    I've had two mouth guards from Sentinel and they've been fantastic. They're thicker than the mouth guard I had gotten from my dentist which I cracked within two months and cost me twice as much. My first Sentinel durability mouth guard lasted almost two years before my severe bruxism cracked it. My new one is going strong; it’s thick enough to protect my teeth and just as easy to sleep in as a standard mouth guard. And the customer service has been so helpful and courteous every time I've needed help.

    Works Great

    After just a couple uses, my mouthguard looks brand new and fits better. I tried to brush it, even with hydrogen peroxide, but it never came clean before. Now, it is nice and clean - I use a combination of filtered water and hydrogen peroxide in the cleaner and change it once a week. Super convenient.

    Exactly what I needed

    As braces are not an option, I needed a little help keeping my front teeth from catching my inner lip while sleeping and causing irritation. This works perfectly! And it is soft and very comfortable and fits very well. I hadn't expected it would work this well for me so I am a very happy customer!

    No complaints

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