An ultrasonic flossing device includes a housing having a proximal portion and a distal portion. An engine is disposed within the housing and is configured to convert input energy into ultrasonic energy and an electronic driving circuit is coupled to both the engine and the power source. A power source is electrically coupled to the engine and is configured to deliver input energy to the engine. At least one acoustic transformer is coupled to the engine, the at least one acoustic transformer being configured to amplify the ultrasonic energy. A main fluid reservoir is configured to store a fluid therein, the main fluid reservoir being coupled to the at least one acoustic transformer such that, upon activation, the fluid transmits the ultrasonic energy to a treatment area.
