ION-Sei Toothbrush – Suppress Bacteria Technology Reviewed

ION-Sei Toothbrush – Suppress  Bacteria Technology Reviewed
Firstly, all-electric toothbrushes work on the same principle, they all use movement (sonic vibrations like Philips Sonicare or oscillations like Oral B) to “mechanically” dislodge and remove dirt and some of the bacteria. I loved the  ION-Sei, sonic vibrations.
It is gentle to the ears and a nice way to start or end the day. It is much quieter very useful for people with muscle weakness, great for children, and people over-sensitive to noise.
For me other toothbrushes sound like a drill at the dentist. (sonic meaning very fast, 31 000 strokes per minute). ION-Sei is the only electric toothbrush on the market that also uses this unique patented “ionic” technology to suppress bacteria that cause plaque.
I noticed the difference weight is it much lighter than other toothbrushes.  It feels strange, to begin with, but that is because the technology is new and gentle. Nice simple 3 brushing modes, 2minutes brushing timer split into 4 intervals. This means I don’t have to think whilst brushing my teeth.

It is a Japanese Technology and German design

When you combine these two nations the result speaks for itself. I love the colour and the design has a very retro vibe to it. For grip it is solid and it feels nice for cleaning my teeth.

How does this work?

There are two different ways ION-Sei uses ionic technology to suppress bacteria:

The ION-Sei uses anUltra Violet (UV) LED light (you can see it when you turn the brush on). That UV light reacts with a Titanium Dioxide bar in the brush handle, to create (release)  ions (negative electrons) which suppress the bacteria’s growth. The negative electrons are sent from that Titanium bar to your mouth via water or saliva during brushing.

The result leaves my teeth smooth and it feels very gentle, unlike other toothbrushes.

ION-Sei also works with your body’s natural electrical charge through a conductor on the handle (that black strip at the back) , producing a weak charge that again inhibits bacterial growth and helps to attract bacteria from teeth onto the brush(thanks to negatively charged electrons). The technology used  in both processes is proprietary and patented. This is always a reassurance of new innovative technology that works.

The TiO2 (titanium dioxide) semiconductor” and “UV LED” negative electron generation, are unique to ION-Sei.

Video Of How It Works

Take the time to watch the video it gives an excellent indication of the technology and how one should understand how to use it.
There is a video by our Brand Ambassador Dr Oliver Dunsch on how to use an electric toothbrush correctly (this applies to any sonic electric toothbrush, not just ION-Sei)  Watch


I liked how it was packaged it is a toothbrush that you could gift to family and friends which is always a good thing. The charging station is neat and not so big which is a real bonus for decluttering your bathroom.

I travel alot and therefore my body runs down as a result I have issues with my gums. So I love how it is very gentle on the mouth and gums, particularly the “soft” head with tapered bristles perfect for gums problems.

I like this idea where an extra small brush head also available to reach all areas particularly useful for people used to small Oral B brush heads. it is worth giving this technology a try, I really love it.
