Oral care implement and monofilament bristle for use with the same

A monofilament bristle comprising:

• coextruded core and sheath components;
• the sheath component having an outer surface and surrounding a first portion of the core component;
• a second portion of the core component protruding from a top terminal end of the sheath component to form an exposed tip portion;
• the sheath component comprising a first material;
• the core component comprising a second material;
• wherein the exposed tip portion of the core component is tapered and has an outer surface with a first roughness and the outer surface of the sheath component has a second roughness, the second roughness being greater than the first roughness.

A monofilament bristle comprising:

• coextruded core and sheath components;
• and
• the sheath component having an outer surface and surrounding a first portion of the core component, the core component further having a second portion protruding from a top terminal end of the sheath component to form an exposed conical tip portion;
• wherein the conical tip portion of the core component has an outer surface configured to have higher coefficient of friction than the outer surface of the sheath component;
• wherein the higher coefficient of friction of the core component is created by one of open pores disposed on the outer surface of the core component or protuberances protruding outwards from the outer surface of the core component;
• and
• wherein the core and sheath components are free of an abrasive material.
