does anyone know a natural/home made remedy kinda thing to whiten teeth ?

I want my teeth to be really white and nice! ive had a brace so they are straight now all i need is them to be white, lol i want something fast as well, not like a gradual one, if i wanted that id just get whitening toothpaste. haha any help appreciated! thanks X x
