the toothbrush as we know it today was invented in 1938. it didn't become popular until wwii when american soldiers were brushing their reeth and the europeans were curious, asking what are you doing? the americans showed the european soldiers and gave them toothbrushes. europeans wrote home about tooth-brushing and their families got a good laugh. after the war the europeans went home to their toothless children and showed them the toothbrush, but it was too late. after a few generations toothbrushes are all the rage, in parts of europe. women in france found alternate uses for them.
