The best. Recommend 100%

Very comfortable, use it every day and sometimes during the day. Easy and for a fraction of the cost! Very happy.

Tongue and cheek guards

Best night guards ever.It has helped me to stop biting my tongue and cheeks. Soft and very comfortable.Thank you.

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!

Fits great!

Custom fit; prevents night grinding

Dentist Quality w/o the High Cost

Easy, affordable and effective. So glad I decided to go with Sentinel instead of going through my dentist. Saved $450!

Easy to use!

It takes only a few minutes to clean my mouth guard now without all the messiness! Glad I bought this UV sterilizer. Works much better than hand cleaning with a toothbrush!
