ION-Sei sonic toothbrush - with ion technology against bacteria
ION-Sei's innovative, patented technology not only removes plaque, but also acts against the bacteria that form it. ION-Sei works with a magnetic titanium dioxide bar. In combination with UV light, this bar generates negatively charged ions, an electric microcurrent (photocatalysis). The natural charge of the teeth and plaque is also negative, but our saliva contains positively charged ions. The difference in charge causes plaque to adhere to teeth. The negative microcurrent generated by the titanium dioxide bar eliminates the charge difference. Positive ions cannot adhere to the teeth any more.
