Abstract:
An oral care implement may include a base portion sized for insertion into an oral cavity and a plurality of flexible, elastomeric elements extending from the base portion, wherein each of the plurality of flexible, elastomeric elements comprises an edge, wherein at least one of the edges comprises a micro edge, and wherein the plurality of flexible, elastomeric elements comprises an element density of less than about 5 mm. Another embodiment of an oral care implement may include a base portion sized for insertion into an oral cavity and a plurality of flexible, elastomeric elements extending from the base portion, wherein at least one of the plurality of flexible, elastomeric elements comprises a first section having a first section edge and a first transverse cross sectional area, and a second section disposed adjacent to the first section along a longitudinal axis of the at least one of the plurality of flexible, elastomeric elements, the second section having a second section edge and a second transverse cross sectional area different from the first transverse cross sectional area. Yet another embodiment of an oral care implement includes a base portion sized for insertion into an oral cavity, the base portion having a base wall and two opposed, side walls connected to the base wall that form a channel for receiving teeth within an oral cavity and a plurality of flexible, elastomeric elements extending into the channel from the base and two opposed, side walls.
