ABSTRACT:
A powered toothbrush which has been designed for improved ergonomics and for assisting the user in using a powered brush in an improved and gentler manner. The powered toothbrush includes a handle portion having a base member at one end thereof. A neck portion extends from the other end of the handle portion with the head coupled to the neck portion. The head includes at least one bristle carrier connected to a drive shaft rotating the at least one bristle carrier in a first rotatable direction. In order to improve the ergonomics and stability of the powered toothbrush, the handle portion is formed asymmetrical about the longitudinal axis of the powered toothbrush and the base member of the handle portion is substantially flat. In this ergonomically-designed powered toothbrush, the width of the base member is less than the greatest width of the handle portion, the depth of the base member is less than the greatest depth of the handle portion, and the height dimension of the neck portion is greater than the height dimension of the handle portion.
