The sound waves generated by the sonic technology ensure a more thorough cleaning. They help remove more food residues from teeth and gum pockets, even at the same water pressure. A Panasonic oral irrigator removes food particles between teeth using a water jet with sonic technology and flushes out plaque from gum pockets. The water jet pleasantly stimulates the gums. The powerful pump provides high water pressure, effectively removing bacteria and food debris with a strong ultrasonic water jet from between the teeth. The water jet flushes out hidden, periodontal disease-causing bacteria from the gum pockets using an ultrasonic water stream. The water jet contains fine air bubbles for pleasant stimulation of the treated areas in the oral cavity.
