The toothbrush rotary part is coupled to the toothbrush head part, but bristles are provided around the circumference surface of the toothbrush rotary part to brush teeth. In addition, the toothbrush rotary part rotates against the toothbrush head part. The driving part transfers rotation power, which is generated by the power of the power supplying part, to the bristle rotary part to rotate the bristle rotary part against the toothbrush head part.
