A U-shaped, ultrasonic toothbrush module to be used with currently available ultrasonic toothbrush hand pieces made of soft thermoplastic, silicone, or latex material with upper and lower bridge receiving spaces formed on opposite sides. The receiving spaces are designed to receive a user's upper and lower bridges when placed into the user's mouth. Disposed on the three inside surfaces of each receiving space are a plurality of bristles which completely contact the exposed surfaces of every tooth when the device is used. The module includes a housing with a pivoting T-shaped member and magnets attached at one end that connects to a standard ultrasonic toothbrush hand piece. Motion generated by the hand piece is transmitted through the T-shaped member and to the U-shaped member. The movement of the U-shaped member generates ultrasonic waves that are transmitted to the surfaces of the teeth and move the brushes when teeth are placed into the upper and lower bridge receiving spaces.
