Powered toothbrush with improved ergonomics

A powered toothbrush comprising:

• a handle portion having a base member at one end thereof;
• a neck portion extending from the other end of said handle portion with a head coupled to the neck portion, the head including at least one bristle carrier connected to a drive shaft for moving the at least one bristle carrier in a first rotational direction;
• and
• wherein a longitudinal axis is coaxial with said handle and neck portions and each of said base member and said handle portion have a width which intersects said longitudinal axis and is parallel to said bristle carrier and wherein the width of said base member is less than the greatest width of said handle portion.
