Toothbrush

Your toothbrush probably isn't as fancy as Napolean's shown in the picture, but it is pretty much the same design.

Before toothbrushes there were toothsticks, a twig with a frayed end. Then, the Chinese exported to Europe toothbrushes made of a natural bristle brush attached to a bone or bamboo handle.

By 1780, William Addis of England carved them from cattle bone and added swine bristles. Natural bristles remained the rule until 1938 when the DuPont Company invented nylon, and nylon continues to be the material of choice for the brush head.

While the first electric model appeared in the 1960s, the fundamental design of the toothbrush has not changed for centuries: a handle to grip and bristles to clean in and around your teeth.
