When you whiten teeth, it only lasts as long as you don't restain them. Professional whitening is best and fastest. It does make your teeth hurt. I like the professional strength crest whitestrips

I use this stuff called like 5 minute bright or 5 minute white. You can he it at cvs and it's pretty good

I heard that activated charcoal works for teeth whitening and it's not as expensive as all the other stuff.
