    Straight and Safe

    Love these guards! I rest (literally, while I’m sleeping) with the peace of mind my teeth are staying straight after braces and safe from the annoying clenching I do at night. Love it!

    Worked great

    Using them as no cheek biting guards. As they don’t get food stains

    Great product and service

    I've ordered a dental retainer from my dentist which was very expensive. It cracked repeatedly and had to be replaced 3 times. I got tired of dealing with them so I decided to try Sentinel based on the good reviews. They've been so responsive, answered my questions promptly and sent out the kits quickly. The retainer has held up beautifully and they look as new as when I received them. Their Customer Service is excellent. I won't go anywhere else.

    My retainers have arrived. They're awesome. Much nicer than the very expensive ones I got from my dentist. Thank you!
