PERFECTION!!!

I had been wearing my beat up retainers for a while I just couldn’t find anyone to replace them for a price that I could afford. I found you guys & they fit perfectly nice & snug, way more durable than the ones I had & they’re just perfect! Let’s just say you guys have a customer for life & I will be purchasing more just to have on hand. Thank you for saving my smile!!!

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!

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.
