fusing ends of the plurality of bristles forming the base of the at least one tuft of brushing bristles so as to form a fused area in one piece, such that an extension of the fused area in a direction transverse to a direction of extension of the at least one tuft of brushing bristles is greater than an extension of the base in the transverse direction before the fusing step;
placing the at least one tuft of brushing bristles on a mold for overmolding the mouthpiece of the brushing part; and
overmolding the mouthpiece and the at least one tuft of brushing bristles and wherein the overmolding step comprises a sub-step of injecting a flexible plastic material, such that the fused area of the at least one tuft of brushing bristles is inside a wall of the mouthpiece and taken in the flexible plastic material forming the mouthpiece, and such that an other end of the at least one tuft of brushing bristles opposite to the fused area protrudes inside the mouthpiece which is formed by the overmolding step.
