97. Apparatus for cleaning the surfaces of teeth underlying the inter-dental papilla portion of the gums in a human mouth by effecting a flossing action, comprising:
-
a flexible, resilient flossing filament having sufficient stiffness to be self supporting; said flossing filament including a base portion, a free-end portion, and an intermediate portion located between said base portion and said free-end portion; said intermediate portion and said free-end portion being capable of being received between adjacent teeth without traversing any contact areas between the teeth from at least the front of the mouth, at least said intermediate portion being composed of a material having sufficient flexibility and resiliency to be capable of effecting the flossing action therebetween without damage to the teeth by imparting a flossing motion to said intermediate portion; at least said intermediate portion being capable of being received in the sulcus between a tooth and the adjacent inter-dental papilla portion of the gum for effecting the flossing action therein; a motive source; and a coupling connecting said base portion of said flossing filament to said motive source and moving said flossing filament with a rotational component to impart said flossing motion to said intermediate portion.

98. Apparatus for cleaning the surfaces of teeth underlying the inter-dental papilla portion of the gums in a human mouth by effecting a flossing action, comprising:
-
a flexible, resilient flossing filament; said flossing filament including a base portion, a free-end portion, and an intermediate portion located between said base portion and said free-end portion; said intermediate portion and said free-end portion being capable of being received between adjacent teeth without traversing any contact areas between the teeth from at least the front of the mouth and being capable of effecting the flossing action therebetween; at least said intermediate portion being capable of being received in the sulcus between a tooth and the adjacent inter-dental papilla portion of the gum for effecting the flossing action therein; a motive source; and a coupling connecting said flossing filament to said motive source to effect motion of said intermediate portion with a rotational component.

100. Apparatus for cleaning the surfaces of teeth underlying the inter-dental papilla portion of the gums in a human mouth by effecting a flossing action, usable with a motive source, the apparatus comprising:
-
a flexible flossing filament having sufficient stiffness to be self-supporting; said flossing filament including a base portion, a free-end portion, and a non-abrasive intermediate portion located between said base portion and said free-end portion; said intermediate portion and said free-end portion having a thickness sufficiently small to be received between adjacent teeth without traversing any contact areas between the teeth from at least the front of the mouth, at least said intermediate portion having sufficient flexibility and resiliency to effect the flossing action therebetween by imparting a flossing motion to said intermediate portion; at least said intermediate portion having a sufficiently small thickness and a configuration to be received in the sulcus between a tooth and the adjacent inter-dental papilla portion of the gum for effecting the flossing action therein, said intermediate portion having sufficient stiffness to be inserted by itself endwise between adjacent teeth and into the sulcus without substantial deformation of shape; said base portion being configured to be releasably connected to the motive source such that the motive source imparts said flossing motion to said intermediate portion in response to operation of the motive source; a filament receiver having a support portion thereof supporting said flossing filament so as to allow said intermediate portion to be moved with said flossing motion; and said filament being uncoiled and having an uncoiled length between said base portion and said free-end portion sized to position said base portion at the motive source for connection thereto and said free-end portion outward of said filament receiver when said filament extends directly from said base portion at the motive source, through and beyond said filament receiver to said free-end portion, with said free-end portion and at least a portion of said intermediate portion located outward of said filament receiver. - View Dependent Claims (101)

102. Apparatus for cleaning the surfaces of teeth underlying the inter-dental papilla portion of the gums in a human mouth by effecting a flossing action, usable with a drive assembly and a filament receiver having a passageway therethrough and an outward end, the apparatus comprising:
-
a flexible and resilient flossing filament having sufficient stiffness to be self-supporting and rotated as a unit along a full length thereof; said flossing filament including a base portion, a free-end portion, and an intermediate portion located between said base portion and said free-end portion; said intermediate portion and said free-end portion having a thickness sufficiently small to be received between adjacent teeth without traversing any contact areas between the teeth from at least the front of the mouth and being sufficiently flexible and resilient to effect the flossing action therebetween; at least said intermediate portion having a sufficiently small thickness and a configuration to be received in the sulcus between a tooth and the adjacent inter-dental papilla portion of the gum for effecting the flossing action therein, said intermediate portion and said free-end portion having sufficient stiffness to be inserted by themselves endwise between adjacent teeth and into the sulcus without substantial deformation of shape; said base portion being configured to be releasably connected to the drive assembly to effect motion of said intermediate portion to produce the flossing action; and said filament being uncoiled and having an uncoiled length between said base portion and said free-end portion sized to position said base portion at the drive assembly for connection thereto and said free-end portion outward of said outward end of said filament receiver when said filament extends directly from said base portion at the drive assembly, through the receiver passageway and beyond the receiver outward end to said free-end portion, with said free-end portion and at least a portion of said intermediate portion located outward of the receiver outward end.
