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 plaque out of the gum pockets. The water jet gently stimulates the gums. The powerful pump provides high water pressure. It eliminates bacteria and food residues with a strong ultrasonic water jet from between the teeth. The water jet flushes out bacteria hidden in the gum pockets that cause periodontal disease using an ultrasonic water jet. The water jet contains fine air bubbles for pleasant stimulation of the treated areas in the oral cavity.
