A brush head (10) and a method for manufacturing a welded tuft assembly (20) for a brush head (10). The method includes inserting a bristle tuft (21) into an opening (51) in a retention element (52). A proximal end of the bristle tuft (23) and a proximal side (53) of the retention element are laser welded to at least partially melt the bristle tuft and at least a portion of the proximal side of the retention element together to create a merged proximal end head portion (26) that holds the welded tuft assembly together.

A brush head (100) and a method of making a tuft spike (20) and a brush head with a plurality of tuft spikes. The brush head includes a matrix (30) having a plurality of receptacles (32) formed therein. A plurality of tuft spikes are each formed of a plurality of bristle strands (22) arranged in a tuft (21) having a free end (25) and a proximal end (23) inserted in a spike body (24). Each tuft spike is disposed in one of the receptacles of the matrix. A brush head neck (40) has a distal platen (42) that is connected to and at least partially encompassed in the matrix.

An oral care implement and/or a cleaning element for an oral care implement. The cleaning element may include an annular cleaning component having an inner surface defining a cavity. The annular cleaning component may be formed from a plurality of arcuate portions with each of the arcuate portions extending from a first end to a second end and terminating in a distal end. A height of each of the arcuate portions may be greater at the second end than at the first end. The plurality of arcuate portions may be arranged in a ring so that the first end of each of the arcuate portions is adjacent to the second end of another one of the arcuate portions.

An oral care implement including a head and a plurality of cleaning elements which may include a first annular cleaning component and a second annular cleaning component. The first annular cleaning component may have a first inner surface defining a first cavity and a first distal end that is sloped from a first low point to a first high point. The second annular cleaning component may a second inner surface defining a second cavity and a second distal end that is sloped from a second low point to a second high point. The first annular cleaning component may located within the second cavity of the second annular cleaning component. The first and second distal ends may be sloped in opposite directions.

A hole perforation plate (60) has a front surface (61), a back surface (62), a thickness (D) therebetween, and a plurality of holes (70), grouped into more than one arrangement (65) of holes (70), wherein the more than one arrangement (65) of holes (70) can be identical or different compared to one another regarding the number of the holes (70), the shape of the holes (70), the size of the holes (70), the distance between the holes (70), the arrangement of the holes (70), and a combination thereof, and wherein the front surface (61) is uneven in the area of the arrangement (65) of the holes (70).

A method of making a brush includes providing a plurality of first filaments, each having a first end and a second end; bringing the plurality of first filaments into a first predetermined shape such that the first ends are arranged side by side on a common contour; fixedly connecting the first ends so that a first pre-tuft having the first predetermined shape and a connected first end is formed; bringing a second tuft element having a first end and a second end together with the first pre-tuft into a second predetermined shape such that the first end of the second tuft element and the connected first end of the first pre-tuft are arranged side by side on a common contour; fixedly connecting the connected first end of the first pre-tuft and the first end of the at least second tuft element so that a final tuft having the second predetermined shape and a connected end is formed; and attaching the final tuft to a brush body by overmolding the final tuft's connected end with a plastic material.
