ABSTRACT:
A hand held toothbrush with multiple levels of bristles on a rotary pad. When the user manually pushes the brush, there is a force created which propels the bristles to catch the irregular surface of the teeth, gaps, and pockets, causing the rotary pad to turn. The bristle's pattern is designed specially to improve the rotary pad to circular more effectively. The advantage of this invention is that even though the user operates the toothbrush in left and right movement, the bristles on rotary pad, converts left and right motion into circular motion.
