<p>An improved toothbrush design incorporating a bristle head (10) including a fixed obtuse angle (15). This toothbrush is designed to be the sole implement needed for dental hygiene. The angle (15) in the bristle head (10) is formed by intermediate (14) and distal (13) segments which each have a straight longitudinal center axis. The intermediate segment (14) is connected to a neck (11) which in turn, is connected to a handle (12), each also having a straight longitudinal center axis. The neck (11), handle (12), and intermediate segments (14) are contiguous and co-linear so as to provide superior cleansing of the lingual, buccal, embrasure, and distal aspects of the teeth and gums.</p> |
