While professor Yuichi Izumi, a pioneer in periodontal disease studies in Japan, treated his patients, he dreamt of a toothbrush that treated teeth and gums carefully and gently, like a manual toothbrush. He took his ideas to the IONIC Corporation, the leading ionic toothbrush company, based in Chiba, Japan. The company had sold over 2 million ionic tooth brushes over its 40-year history, and with professor Izumi, developed a brand-new sonic action toothbrush, which they named IONPA. By adding ion power to a gentle, therapeutic sonic action, a synergy occurs. The ionic effect efficiently depolarizes and thus, loosens plaque’s grip on the tooth surface, allowing for easy removal with the gentle pulsations of the IONPA handle. IONPA does more to clean teeth, and does it more easily, than either manual or electric brushing alone.
Studies prove that IONPA cleans more plaque below the gumline (as much as 196% versus manual*).
