An interdental cleaner with a rod-like support which has a cleaning device in an axial end region. The cleaning device includes a cover on the support made of a soft-elastic plastic, and structuring is formed on the outside of the cover having a plurality of fingers protruding with radial components from the cover, which fingers are made of the same material as the cover and are connected as one piece thereto. The structuring additionally has a bristle edging with a plurality of bristle bundles protruding with radial components from the cover and/or individual bristles which are each formed from pre-produced bristles embedded in the cover and/or in the support.

A head for an oral care implement has an outer rim and an inner portion. The head comprises at least one tuft of filaments of a first type and at least one tuft of filaments of a second type. The at least one tuft of the first type is arranged at the inner portion of the head and comprises a plurality of filaments, each filament having a longitudinal axis and a substantially circular cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The at least one tuft of the second type is arranged at the outer rim of the head and comprises a plurality of filaments, each filament having a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis, the cross-shaped cross-sectional area having four projections and four channels, the projections and channels being arranged in an alternating manner. The at least one tuft of filaments of the second type has a packing factor within a range from about 40% to about 55%.
