ION-Sei's superpowers lie in its patented technology: Whereas most electric toothbrushes only remove some of the plaque and bacteria (S. Mutans*), ionic technology actually suppresses the bacteria causing plaque too.The ION-Sei electric toothbrush uses an Ultra Violet (UV) LED light that reacts with a Titanium Dioxide bar in the brush handle, to create ions that suppress the bacteria that cause plaque.The negative electrons are sent to your mouth via water or saliva. Although ION-Sei uses advanced technology, it harnesses nature using "water and light".ION-Sei also works with your body's natural electrical charge through a conductor on the handle, producing a weak charge that inhibits bacterial growth and helps to attract bacteria from teeth onto the brush.The technology used to create these super powers are proprietary and patented. The TiO2 (titanium dioxide) semiconductor" and "UV LED" negative electron generation, are unique to ION-Sei.* Streptococcus mutans is a bacteria that inhabits the human oral cavity. It produces plaque and acids that break down tooth enamel and cause dental caries (cavities).
