    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.

    Cheesefingers barely brushed by. (*~*)
    Clonge

    ...or all of finger's teeth have fallen out.

    ....simple, if hand driven, or is it effective ?


    ....the electric is not simple and is proven to be more effective 


    ....both are simple to use

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