If i brush my teeth like 20 times in a day would it whiten my teeth ?

haha kinda curious. i use arm n hammer whitening. is there a certain limit per day before it doesnt do anything?
--------------------
Every one of the previous posters are incorrect. Brushing 20 times a day will not hurt your enamel. Enamel is a very hard substance that cannot be harmed that way. If, however, you are brushing too vigorously or with a brush other than a soft bristled one, you could cause problems to your gums. (recession) The only ways there are to really whiten your teeth is to use Crest Whitening Strips or have it professionally done at your dentists office.
