Brazil also has an interesting relationship with teeth. When I was there, I noticed people brushing teeth after lunch. This happens even at corporate offices -- the restrooms would be full of people brushing and flossing after meals. People brought toothbrushes to work. There was even a floss (fio dental) dispenser.
