Abstract
An improved toothbrush design incorporating a bristle head including a fixed obtuse angle. This toothbrush is designed to be the sole implement needed for dental hygiene. The angle in the bristle head is formed by intermediate and distal segments which each have a straight longitudinal center axis. The intermediate segment is connected to a neck which in turn, is connected to a handle, each also having a straight longitudinal center axis. The neck, handle, and intermediate segments are contiguous and co-linear so as to provide superior cleansing of the lingual, buccal, embrasure, and distal aspects of the teeth and gums.
