<p>Provided are an oral care brush, wherein a twisted brush, which is obtained by disposing filaments that are tapered at both ends in a helical form by twisting a wire, is bent to form a quarter of a circle or more, and a manufacturing method therefor. The oral care brush is characterized in that a twisted brush, which is obtained by disposing multiple filaments that are tapered at both ends in a helical form by interposing the filaments between two wires and twisting the wires, is bent to form a quarter of a circle or more. The manufacturing method therefor is an oral care brush manufacturing method characterized in that a twisted brush, wherein multiple filaments that are tapered at both ends are interposed between two wires and the wires are twisted to dispose the filaments in a helical form, is bent so as to form a quarter of a circle or more.</p> |
