Abstract: The structural design of a toothbrush according to this invention mainly improves the shortcomings of the conventional toothbrush having difficult access of the bristles to the interproximal areas and the areas of the tooth surface at opposite sides of a person's mouth and blind spots on cleansing certain difficult-to-reach areas. The bristle head and the handle of such toothbrush of the invention are one-piece; and such bristle head is implanted with bundles of bristles; wherein the bristle head is bent downward with an angle between 45 degrees to 90 degrees relative to the horizontal axis of the handle (that is of any angle within the range of 45 degrees to 90 degrees between the bundles of bristles of the bristle head and the axis of handle) allowing such toothbrush to extend into the areas of the tooth surface at opposite sides of the mouth or the interproximal areas for a more effective cleaning of the teeth, and it in turn reduces mouth disease and provides a good preventive measure for teeth hygiene, and definitely a professional health care toothbrush.
