Abstract
A toothbrush having multiple bundles of bristles preferably arranged in two rows spaced apart from one another, and each bundle independently anchored into the front surface of the brush head with bundles in the opposed rows directed inwardly toward one another and angled toward a common intersection, allowing the free tip ends of the bristles to terminate in a single, common row. Each bundle is free standing and the bundles in one row have alternating relation with the bundles in the other row or rows. Thus, the free tip ends of the bristles in each bundle terminate independently and unopposed, allowing the bristles in each bundle to have movement independent from those in adjacent bundles, apply less force against teeth, and provide less abrasion of the rounded outward tooth surfaces at or near the gingival level during the cleaning of interproximal areas of teeth.
