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.

Product is great, and came quickly!!!

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~~

PERFECT FOR DAYTIME USE Teeth impression process was easier than I thought and I received my mouthguard very quickly after sending it off. If you're like me and clench your teeth during the day, this is the mouthguard for you! I love the fit of it. I love that I can communicate easily. I do take it out when I eat and drink. My headaches and jaw pain are gone and I can feel that my teeth are thankful I'm not clenching down constantly! A lifesaver for business professionals.

This mouth guard is awesome! Easy to create your own teeth impression. My mouth guard came quick and fits like a glove!

Fits better than expected! It's by far the most comfortable mouth guard I've ever worn. It stays in place. I can talk with it in no problem. I will be back! Thank you!

The hard option is where it's at! I tried the soft type first and found that it was too flexible for my liking. Switched to the hard guard (they allow you to switch types if you're not satisfied) and this is EVERYTHING! My tension headaches are gone and I love how comfortable it is. I only had to pay the cost to upgrade ($20). Fast, affordable and the fit is fantastic!

This is my second time buying this because my dog got it the first time! I only wear this sometimes during the day and it has helped so much with my stress headaches! It’s easy, worth it and gives the best results.
