Abstract

A multiple part toothbrush includes a handle stem having a connecting part projecting outwardly from one end thereof and extending in a direction which forms an angle of about 7.degree. with respect to the handle stem. A brush head has a cavity therein, the connecting part being snugly receivable within the cavity to effect a removable mounting of the brush head on the handle stem. The connecting part can be inserted into the brush head cavity with either of two different orientations, whereby two different orientations of the plane defined by the bristle ends with respect to the handle stem are possible.
