  • Dan Hale

    I LOVE my no show guard and I wear it at night! Beats the standard night guards in comfort. No contest. The ones I used to wear would press against my front teeth. This guard style is the best I’ve found for my teeth clenching. I sleep soundly and my jaw pain is barely noticeable anymore.

    My dentist has been telling my I grind my teeth and I finally did something about it. I ordered a night guard and a day guard. Both fit perfect and I particularly love the comfort of this day guard. Taking the impressions was a bit of a challenge for me, I had to redo them but they provide free materials so no problem. I also want to mention Sentinel’s excellent customer service. Very friendly and helpful! I highly recommend~~
