how to whiten up your teeth without having to go to the dentist?

i wanted to know how to whiten up my teeth without having to go to the dentist. its white but i want it to be pearly white so that it shines.

i've heard crest white strips are one of the best whitening strips . with most of their products, you can start to see whiter teeth after 3-5 days . crest whitening strips classic works good and cost $25 u.s. crest advanced seal works the best out of all the products but costs more ( $45 u.s. ) hope your teeth come out white :)
