An oral cleaning device comprises a body which carries a set of projections. An actuator device is associated with one or more of the projections in the form of an electroactive polymer structure for adjusting a position of the associated one or more projections. This enables dynamic control of the cleaning function.

The double action cleaning tool of the present invention includes a dynamic double action dual brush head and a handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action cleaning tool stores energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.

The bristles of this toothbrush design is made of flexible material, the bristle component is not fully attached to the tooth brush handle. Beneath the bristle component is a wire/lever actuator mechanism that could be either pushed or pulled, via an attachment of the wire or lever to a button on the handle of the toothbrush. When pushed or pulled depending on where the wire is attached to the flexible membrane, it will become semi oval or half circle shape. When the user is done and the button is released because of the flexible material used in the construction of the membrane, stored kinetic energy and will return the button to its neutral position. And the membrane to its normal flat or slightly curved position so the toothbrush could be used as a traditional toothbrush design.

The head of the toothbrush, rotating on its axis 180 degrees and 90 degrees to each side. A button is placed in the handle of the toothbrush with is connected to a lever, when the button is moved forward or backwards, it will apply force to the rotating pin. This is done by either using a gear system or simply attaching the lever to the side of the pin in order to transfer kinetic energy. The top of the rotating pin is attached to the part of the toothbrush that holds the bristles, which through rotating pushing or pulling the button can rotate the bristles 90 degrees each side or 180 degrees total. The bristle components can be composed of flexible material. This bristle part can be replaced or changed. Shorter, longer, wider, narrow, soft and harder bristle attachments can be used, based on the individual's needs.

The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.

A toothbrush (10) includes a brush assembly (16) with at least three bristle arrangements (12), each having opposing inwardly-directed bristles (122, 124, 126) for simultaneously contacting facial and lingual surfaces (52, 54), and preferably also occlusal surfaces (56) of the teeth (50). Flexible linkages (14), interconnecting the bristle arrangements (12), maintain a relative spacing between the bristle arrangements (12) while allowing variation of an effective curvature of the brush assembly (16) such that the bristle arrangements (12) can ride along, and conform to a non-uniform curvature of, the arch of teeth. The toothbrush (TO) preferably also includes an actuation mechanism (22) for generating to-and-fro motion of the brush assembly (16) along the arch of teeth, most preferably combined with a more rapid small-amplitude oscillatory motion.
