A vibrating toothbrush includes a power source with a charging coil or bobbin wrapped thereabout. The power source is attached to a motor that is directly and rotatably connected to a rotatable magnet. The rotatable magnet has a plurality of alternating pairs of magnetic poles and is adjacent a permanent magnet. The permanent magnet is disposed on a first end of a lever arm with a brush attached to the other end of the lever arm. The rotation of the motor causes the rotatable magnet to rotate. The alternating polarity of the magnetic poles on the rotating magnet results in the permanent magnet oscillating, which in turn oscillates the lever arm and vibrates the brush on the second end of the lever arm.
