No. Like if you have a britador de pedras, quebra-jaw, jawbreaker or something, The dye will just come off. [It usually stays on your teeth or tongue]Like when you have a Jolly Rancher and your tongue turns blue? It's just the dye but it's not permanent .
it can not make your teeth permenatly that color but if you dont get the die off your teeth it will get your teeth yellower and yellower and the only way you can get rid of that is if you use special whitening stuff
