Would it be effective to use regular bleach to whiten teeth?

While I know this isn't a safe method, would it be effective to use regular house bleach to whiten teeth? How long do you think it might take?
--------------------
Buy a Crest Pro Spinbrush. I bought one a week ago for $7.99 [plus tax] and my teeth are about 3 shades whiter by just using the brush and regular toothpaste. The brush has a round brush that spins on top, and a square brush that moves up and down on the bottom. Your teeth will be squeaky clean after you use it, and the stains I had on my teeth are almost gone, and like I said my teeth are about 3 shades whiter in only a week.
