ABSTRACT:
A toothbrush for improved dental hygiene providing a body formed with a curved bristle head joined to a substantially straight handle by an offset neck. The curved bristle head tangentially joins the neck and extends therefrom with a decreasing radius of curvature to the extremity thereof. A plurality of bristle bundles are mounted on the concave side of the bristle head and extend substantially perpendicular to a cord joining the ends of the bristle head to free ends located in a flat plane substantially parallel to such cord. A retractable toothpick is mounted in the end of the handle remote from the bristle head and is movable between a retracted position within the handle and an extended position in which it extends beyond the end of the handle.
