No. Like if bạn have a jawbreaker, đòn bẩy hoặc something, The dye will just come off. [It usually stays on your teeth hoặc tongue]Like when bạn 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 bạn dont get the die off your teeth it will get your teeth yellower and yellower and the only way bạn can get rid of that is if bạn use special whitening stuff
