    • A head for an oral care implement has a longitudinal length extension extending between a proximal end and a distal end, an outer rim and an inner portion. The head comprises at least two tooth cleaning elements of a first type and a plurality of tooth cleaning elements of a second type, the tooth cleaning elements of the first type being arranged at the inner portion of the head, and the plurality of tooth cleaning elements of the second type being arranged at the outer rim of the head, thereby surrounding the tooth cleaning elements of the first type. The tooth cleaning elements of the first type are tufts of a first type comprising a plurality of filaments. The tufts of the first type are arranged substantially parallel to each other. Each tuft has a substantially rectangular or oval cross-sectional shape with a longer length extension from about 4 mm to about 8 mm and a shorter width extension from about 1.5 mm to about 2.5 mm, wherein the longer length extension defines an angle α with respect to the longitudinal length extension of the head of about 25° to about 60°.
