A power toothbrush appliance () and a method for tuning a brushhead assembly system () thereof. The appliance includes a handle portion (), a drive assembly and a brushhead assembly system (). The drive assembly includes a DC motor () and an eccentric coupling () which drives the brushhead assembly system by means of a yoke mechanism. The brushhead assembly system includes a beam portion () which moves laterally about a pivot (). A brushhead () is attachable to and removable from a distal end of the beam. The beam is tunable by changing the stiffness thereof, or the length thereof, or the cross-sectional moment thereof, in order to control the resonant frequency of the brushhead assembly system relative to the drive frequency of the appliance to maintain the amplitude of the brush member within a range of 1.0-2.5 mm, preferably 1.75 mm.

The guidance assembly is used for precise cleaning of interproximal spaces of teeth. The guidance assembly includes a base portion () for contacting the surfaces of teeth and gum region, adjacent the interproximal space, the base portion being approximately 12 mm in diameter to provide stable contact with the teeth and gum region. The guidance assembly also includes a tip portion () which extends forward of the base portion and includes an opening () through which the droplet spray is directed coincident with the plane of the interproximal space.

The combination of a power toothbrush and a charging system includes a charging base unit () having a charging coil () wound around the interior surface () of a portion of the charging base unit, and connectable to a source of electric power and a rinsing vessel () adapted to hold a toothbrush, the rinsing glass having a lower surface () configured to fit onto the upper surface () of the charging unit. The vessel is configured to hold a toothbrush in such a manner to prevent the toothbrush from tipping over when placed in the vessel, and further configured relative to the base unit that charging of the power toothbrush can occur between a pickup coil () in the handle of the toothbrush and the charging coil in the base charging unit.

A power toothbrush appliance () which includes a user interface assembly () having a hidden interface panel () and a method of making same, the appliance including a handle () and a brushhead assembly () with a brush member () for cleaning teeth. The user interface assembly is structured so that when the appliance is in the off condition, the user interface panel is blank, and when the appliance is in an on condition, the indicia associated with the selected operating mode of the toothbrush is illuminated and visible to the user. The interface panel includes a first paint layer of gray or black paint () on a translucent handle (). The mode indicia are etched () to the handle in the first paint layer. A second paint layer of white paint () is applied over the first layer and is light-transmitting so that when the toothbrush is on, the selected indicia are visible to the user.

A dental appliance having a passive arrangement for drawing liquid from a reservoir () in the appliance by action of a stream of gas, which can be provided by a source of compressed gas () or other system. The liquid mixes with the gas, resulting in liquid droplets which are directed through an orifice () at the end of a nozzle portion () of the appliance.
