An oral care device may include: a body including a head; a plurality of teeth cleaning elements extending from the head; a first sacrificial electrode on the head; a second sacrificial electrode on the head and spaced apart from the first sacrificial electrode; a power source; and a controller configured to alternate between an ON state and an OFF state, wherein: in the ON state the controller operably couples the power source to the first and second sacrificial electrodes to create an electric potential between the first sacrificial electrode and the second sacrificial electrode, the electric potential having one of a first polarity and a second polarity, and for each successive transition from the OFF state to the ON state, the controller is configured to alternate between the first polarity and the second polarity.

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.

Mouthpieces for fitting inside a user's mouth and cleaning the teeth, tongue, gums and/or roof of the mouth are provided. The mouthpiece is a hands free toothbrush designed to fit inside the mouth and clean the teeth, tongue, gums and/or roof of the mouth. The mouthpiece is made up of flexible material and is sized to fit the user's mouth. It contains intricately designed tube structures. It will clean the user's mouth, teeth, tongue and gums. The mouthpiece slips in to the mouth and fits or approximates the contour of an individual's teeth. When not in use, the mouthpiece can be kept in its own container for sanitary purposes.

A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

A powered oral care apparatus (2) has a pump-free fluid delivery system for delivering one or more fluids to the oral cavity of a user. The oral care apparatus may employ an oral care assembly (30) that has a capsule member (38) for delivering fluid through a number of openings (31, 46) in response to movement of a head (4) of the oral care apparatus. The oral care apparatus may also employ an oral care assembly (62) having a diaphragm member (84) and a mass member (88) coupled thereto wherein, in response to motion being imparted to the brushhead, the mass member and diaphragm member generate a pumping force to cause fluid to be delivered out of the oral care assembly.

The toothbrush includes a handle portion which includes a power drive system (14) and further includes a brushhead assembly (20), which includes a brushhead arm having a brush element (21) at a distal end thereof A drive train assembly (12) is responsive to a drive signal from the power assembly for converting the action of the power assembly to a motion of the brushhead assembly. A magnet (30) is secured to the rear of the drive train, with a Hall effect sensor (32) mounted within the magnetic field produced by the magnet as the toothbrush moves in operation. Pressure on the brush element produces a phase shift of the Hall sensor output. A processor (15) determines the value of the phase shift of the Hall sensor signal as pressure is applied to the brush member and produces a signal indicative of the pressure applied by using stored information (71) which relates phase shift to pressure for the particular appliance.
