Default toothpaste idea

looking for a little help doing a toothpaste efficiency comparison with 4th grader. He would like to obtain extracted teeth, mount and stain with coffee, etc. then use various toothpastes on the market and brush for a set number of days to see which cleaned(whitened) the teeth the best. Good idea? also, if we cannot get teeth do you think another material might be good?? thanks
