Abstract: A flossing device to floss bacterial plaque off tooth structures, including teeth and osseous implanted abutments, said flossing device comprising a leader with affixed cord. The leader is provided with a hook portion, preferably formed by and integral with the leader; the leader being bent back upon itself at an acute angle which permits ready insertion of the leader between adjacent tooth structures and which permits ready access to the leader as the free end of the hook effectively hooks about the tooth structure and extends outward of the tooth structure for convenient grasping by the user, upon retraction of the leader. The terminal free end of the hook may be enlarged and blunted for secure grasping. The flossing cord is singular, being constructed of a multiplicity of braided strands for entrapment and removal of plaque from the tooth structures.
