The ION-Sei toothbrush is not an ordinary electric toothbrush. It utilizes the properties of light, metal, and electricity to clean your teeth. Once you activate the integrated UV light and the titanium dioxide rod, negatively charged ions begin to neutralize plaque-causing bacteria. Additionally, up to 31,000 sonic vibrations provide an effective yet gentle cleaning for your gums. You can adjust the vibrations to your preference in three levels. With the two-minute timer, you will always maintain the ideal brushing time. To ensure that you brush all areas of your mouth for the same duration, the toothbrush pauses every 30 seconds.
