Default well....

i Dont really think this is a great project, because u would need to view the chenical reaction i which toothpaste withens teeth but that TOTTALY up to U. i Think the best way to figure this out is to determine the amount of baking powder in each[ althought usualy be better to take at least three different people and then asign each a differnt toothpaste and c the results, but then they will have to have the same amount of cleaness]. I would use the toothpaste websites and the tooth paste box fo info.
