    Abstract: An oral care device may include: a body including a head; a plurality of teeth cleaning elements extending from the head; a first electrode on the head; a second electrode on the head and spaced apart from the first electrode, wherein at least one of the first and second electrodes is a sacrificial electrode; a power source; and a controller configured to operably couple the power source to the first and second electrodes to create an electric potential between the first and second electrodes so that ions are released from the sacrificial electrode during a brushing session; wherein the controller is configured to change a magnitude of the electric potential the brushing session ends.

    Abstract: An oral care device having a head with cleaning elements and a handle coupled to the head. The handle may include a selectively rotatable ring arranged between the head and a distal end of the handle that is configured to allow a user to select a desired mode of operation of the oral care device. The handle may include a selectively illuminated light that is configured to display at least one color that visually indicates that certain behaviors, patterns, and/or consistent habits have been performed successfully. The handle may include a processor configured to track a duration of a user's brushing session, a light ring on a bottom surface of the handle, and a pressure sensor. Respective portions of the light ring may be selectively illuminated by the processor to visualize progress toward achieving a predetermined brushing routine time and/or to visualize an over-pressure condition sensed by the pressure sensor.

    Abstract: An oral care refill head (300), the oral care refill head (300) may be detachably coupled to a handle (200). The handle (200) may include a stem (250) that is received within a connection cavity (326) of the oral care refill head (300). The stem (250) and the connection cavity (326) may have specific geometries and structures to ensure an adequate coupling therebetween. An oral care implement (100), the oral care implement (100) have a pressure sensing assembly, excessive pressure applied onto the oral care refill head (300) will cause the motor (140) and a motor chassis (401) to rock. As the motor chassis (401) rocks, a contact element (456) thereon will actuate a pressure actuator element (455). In response, a control unit (150) may initiate generation of a user perceptible signal to inform the user of the excess pressure.
