A sonic toothbrush system includes an electric motor, a brush shaft, and a drive assembly. The electric motor includes a drive shaft. When the electric motor is caused to operate, the drive shaft continuously rotates until the motor is caused to stop. The drive assembly is coupled between the drive shaft and the brush shaft. The drive assembly is configured to convert the rotation of the drive shaft into sonic oscillation of a toothbrush head supported on an end of the brush shaft.
