  • Publication number: 20210235853
    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.

  • Publication number: 20200288858
    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.
