    Abstract: An oral care implement including an elongated body having a head portion supporting plurality of tooth cleaning elements and a handle portion defining an outer surface. A grip control component is disposed on the handle portion and includes a pair of transversely spaced apart control surfaces separated by a longitudinally extending channel. The control surfaces are elevated above the outer surface of the handle portion and positioned to engage a user's thumb. The control component is operable to tilt the head portion at an upward or downward angle relative to a vertical plane of a user's teeth when the control component is grasped between the user's thumb and forefinger for producing a proper brushing angle at the gum line.

    Abstract: A monofilament bristle (200) is disclosed that comprises coextruded core (210) and sheath components (220). The sheath component (220) has an outer surface (218) and surrounds a first portion (215) of the core component (210). A second portion (216) of the core component (210) protrudes from a top terminal end (203) of the sheath component (220) to form an exposed tip portion (203). In one embodiment, the exposed tip portion (203) of the core component (210) has an outer surface (217) that includes friction-enhancing features. In another embodiment, the exposed tip portion (203) is tapered and has an outer surface (217) with a first roughness and the outer surface (218) of the sheath component (220) has a second roughness, the second roughness being greater than the first roughness. In a further embodiment, the core component (210) has an outer surface (217) configured to have higher coefficient of friction than the outer surface (218) of the sheath component (220). In other embodiments, an oral care implement (100) including one or more of the monofilaments described herein is disclosed.

    Abstract: An oral care product array includes a handle component and multiple refill components therefor. The handle component includes a power source. A first refill component includes a first light generating module which emits light in a first spectrum from the first refill component. A second refill component includes a second light generating module which emits light in a second spectrum from the second refill component. Each refill component has a coupled state, when coupled to the handle component, and a decoupled state, when decoupled from the handle component. When the first refill component is in the coupled state, the first light generating module is powered by the power source to emit light in the first spectrum. When the second refill component is in the coupled state, the second light generating module is powered by the power source to emit light in the second spectrum.
