      A toothbrush is not a simple machine, it does not work on the principle of levers, effort, and load.


      It's not a machine at all in mathematical terms. A "machine" is that which performs "work", i.e. transfers or converts energy.


      You arm moving the toothbrush is a machine by this definition, however.

            If you're talking about an electric toothbrush, it is powered by a battery to make the brush spin around.
