Works great for showing kids where they need to brush more. 1/2 tablet is more than enough for a kid. We have two kids and they each get a half. Still have to rinse their mouths once or twice after spitting the dye out otherwise their entire mouth is nearly black and doesn't really show the plaque. We use our cell phones to take pictures with the flash and then show the kids the photos and send them back to brush again. They think it's fun, and seems to be helping them learn how to brush better.
