Abstract
A toothbrush is provided that includes a handle formed with an elongated cavity and a mouth opening at a terminus thereof. At least two stems consisting of a bar and a brushhead are hingedly supported at a first end of each bar within the elongated cavity. The toothbrush enables a user despite incorrect stroking to convert lateral motion into a corrected up and down movement of the bristles.
