A cleaner apparatus for use in a dental prophylaxis process includes an applicator defining a curved occlusal wall, a buccal wall, a lingual wall, and a distal wall, each of the buccal wall, the lingual wall and distal walls extending outwardly from the occlusal wall and forming a curved applicator configured to receive a patients teeth in one of the maxillary arch and mandibular arch of the patient. The applicator being configured to receive and contain a cleaning agent in the cavity during a teeth cleaning process. An ultrasonic transducer is embedded within each of the buccal wall and the lingual wall of the applicator. A controller is electrically coupled to the transducers for powering the transducers and controlling the operation thereof, and the cleaner apparatus for cleaning a full arch of a patients teeth via cavitation of the cleaning agent resulting from ultrasonic radiation transmitted from the transducers.
