How do i get my teeth whiter?

i wanna whiten my teeth but the crest stripes dont work for me what else works?
--------------------
these new colgate whitening toothpastes are really great, and they are coming out with these incredible flavors and tastes, like the once with the rasberry flavors and breath mint crystals, those are really yummy, i wish I can eat them after I brush my teeth with them, hehe, but yeah, they also whiten teeth, because if you look at my ugly face, the nicest thing about it is my sparkling white teeth okay thank you very much
