Abstract: An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface, the central bristle tuft terminating in a domed distal surface. Furthermore, the oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. Each of the perimetric bristle tufts may have an inclined distal surface that slopes downward towards the central bristle tuft. The bristle bearing surface of the head may have a total surface area (TSA), and the toothbrush may include a tooth cleaning element field having X number of tooth cleaning elements that collectively occupy a total cleaning element area (TCEA) such that 1 X × T ⁢ C ⁢ E ⁢ A T ⁢ S ⁢ A = Z and Z is in a range of 0.04 to 0.065.

Abstract: An oral care implement (100) having a head (120). The head (120) has a support structure (130) and a monolithic cleaning unit (140) that is coupled to the support structure (130). The head (120) has a side surface (123) that includes a first lateral portion (124) and a second lateral portion (125). The monolithic cleaning unit (140) includes a base portion (141) that is coupled to the support structure (130) and a plurality of bristles (150) extending from the base portion (141). The plurality of bristles (150) include a plurality of first peripheral bristles (171) positioned adjacent to the first lateral portion (124) of the head (120), a plurality of second peripheral bristles (172) positioned adjacent to the second lateral portion (125) of the head (120), and a plurality of central bristles (175). The first and second peripheral bristles (171,172) all extend obliquely from the front surface (121) of the head (120) and the central bristles (175) extend perpendicularly from the front surface (121) of the head (120).

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.
