Toothbrush bristle element having serrated outer structure

Abstract

A toothbrush includes a handle having a bristle head on one end, and a number of bristle elements each having a lower end portion attached to the bristle head, and each having an upper end portion located distal to the bristle head, and the bristle elements each include a number of scraping protrusions extended radially and outwardly from an outer peripheral portion, and the scraping protrusions each include a triangular shape having a sharp outer end for allowing the scraping protrusions of the bristle element to form a star-shape configuration and for frictionally engaging with the teeth of the user and for increasing or facilitating the tooth brushing effect.

         1 . A toothbrush comprising:
 a handle including a bristle head provided on one end portion of said handle, and said bristle head including an upper portion, and   a plurality of bristle elements each including a longitudinal structure having a lower end portion attached to said upper portion of said bristle head, and having an upper end portion located distal to and spaced from said upper portion of said bristle head, and   said bristle elements each including a plurality of scraping protrusions extended radially and outwardly from an outer peripheral portion of said bristle element, and said scraping protrusions each including a triangular shape having a sharp outer end for allowing said scraping protrusions of said bristle element to form a star-shape configuration.   
     
     
         2 . The toothbrush as claimed in  claim 1 , wherein said scraping protrusions of said bristle element are equally spaced from each other.
