Abstract
A motor-driven toothbrush including a brush head disposed at an angle to the brush handle wherein the brush head partakes of rotary or arcuate motion, wherein the handle includes a flexible or articulated section permitting the brush head and an end portion of the handle to deflect with respect to the remainder of the handle as the brush head engages the teeth. The elastic section may be a flexible portion or may be a bellows-like member. The drive for the brush head extends through the elastic section and to the brush head. The flexible section permits the brush head to tilt angularly through an angle either greater or less than 90 degrees with respect to the axis of the brush handle. The brush head is attachable to a separate handle having a drive device.
