The home teeth whitening system is a small, easy to use handheld device (which one comment said the was FDA Approved – still trying to verify this but may White Light Smile take some time) with a curved plastic edge on one side that fits into your mouth as a simple teeth whitening tool. Inside that plastic edge you’ll see lights. You place a gel tray in your mouth then hold these lights against your teeth and clamp down while they go to work whitening your teeth. http://drozforskolin.org/white-light-smile-reviews/
