Abstract: A dental appliance including a curved tubular extension consists of a housing formed with first and second elongated recesses, and first and second pumps secured to the housing for pumping a paste and a fluid directly through the first and second recesses, respectively. A flexible drive shaft is rotatably disposed within the curved tubular extension and one end of the drive shaft is operatively connected to an electric motor within the housing. The housing and the tubular extension formed thereon are divided into first and second portions, which may be separated along a plane substantially intersecting the longitudinal axis of the motor and that of the flexible shaft. A bearing rotatably supports the flexible shaft extending therethrough and secures the first and second portions of the tubular extension together. A toothbrush is drivably attached to the other end of the flexible shaft for rotating therewith.
