UV LED light and patented Tio2 bar

Whereas most electric toothbrushes only remove some of the plaque and bacteria, ionic technology actually suppresses the bacteria causing plaque too.

UV light strikes the TiO2 (titanium dioxide) bar and makes the OH radical (hydroxyl radical), generating IONs. The OH radical and ION (OH-) helps to suppress bacteria attachment and therefore plaque formation, travelling further and deeper into your mouth.

The ION-Sei is an innovation that works with your body’s natural electrical charge—producing an opposite charge that suppresses plaque and bacterial growth, and helps to attract bacteria and plaque from teeth.

ION-Sei Organic Design

The ION-Sei is an interesting fusion of Japanese thinking and philosophy, combined with top German product design. Organic lines on the toothbrush are inspired by Japanese culture: the water needed to activate the technology, trees and stones.

Our colours were inspired by people’s lives, and how they use their toothbrush morning and night. Life, love, teeth - with ION-Sei you can embrace new technology, love and care for your teeth, and choose the toothbrush colour that fits your life best.

ION-Sei Lake Blue

Lake Blue

玉みがかざれば 光なし
If you don’t polish a stone, it will not shine.

Water makes up around 70% of our bodies and planet. It was a big part of the product inspiration as it’s needed for the ION-Sei to work. The exact colour comes from Japan’s bluest, most beautiful lakes.

Day White

天は みずから助くる者を助く
Heaven helps those who help themselves.

Natural white isn’t clinically white. Think of daylight, a natural light that takes on the hue of the day—it is off-white, with a slight grey tinge that reflects clouds and the sky.
