Abstract: Oral care devices are provided that are capable of ejecting an air-liquid combination. In some implementations, the oral care devices include an applicator including a passageway within the applicator for directing the air-liquid combination therethrough; a plurality of brushing elements extending from a base at a head of the applicator to free distal ends, the head being sized to fit in a user's mouth; and a flexible nozzle in communication with the passageway and extending outwardly beyond the base at the head, the flexible nozzle configured to direct liquid droplets of the air-liquid combination beyond free distal ends of the brushing elements during brushing.

Abstract: Oral care devices are provided that include a pumping assembly for dispensing a fluid, e.g., a dentifrice, from the oral care device.

Abstract: Oral care devices are provided that include a first component and a second component removably engaged with the first component; the first and second components having a respective fluid passageway extending therethrough, the respective passageways capable of fluid communication while the first and second components are engaged; and at least one of the first and second components including a sealing member constructed to allow fluid communication between the first and second passageways when the first and second passageways are engaged and to close the associated passageway when the first and second components are disengaged. Oral care devices are also provided that include a replaceable and refillable cartridge.

Abstract: Toothbrush heads, e.g., for power toothbrushes, are provided. The toothbrush heads include a support member and a plurality of bristles or tufts of bristles extending from the support member, the bristles or bristle tufts having different lengths. The contour of the bristles may be selected to allow substantially all of the bristles to contact the dentition during brushing.
