An oral care system for cleaning teeth and gums includes a housing, an oral hygiene unit, and a gooseneck arm attached to the housing and releasably coupling the oral hygiene unit to the housing, the gooseneck arm being adjustable to hold the oral hygiene unit at a defined position and orientation relative to the housing. In a preferred embodiment, a distributed feedback based diode laser sensor operating at a wavelength near 1996. The device comprises an automatic routingdialling module connected to the data communication interface, adapted to establish an automatic access to a modem connected to the data communication interface by automatically selecting one of a plurality of possible connection parameters. A processor is responsive to the frequency signals from each of the filters and generates control signals in response to gestures made by the user to command operation of a device.
