Nanotech toothbrush eliminates the need for toothpaste

A group of Japanese designers have set about trying to modernise the humble toothbrush.

Utilising nanotechnology, Kosho Ueshima and Japanese firm Yumeshkunin have partnered to create a toothbrush, called Misoka, which cleans your teeth without toothpaste.

Misoka’s power lies in hi-tech bristles that are apparently coated in ‘nanosized mineral ions’.

The theory is that, after dipping the brush in water to loosen the ions, they will be transferred to your teeth while brushing, removing stains and forming a protective layer.

“Even without toothpaste, your teeth stay as shiny and clean as though you just walked out of a teeth-cleaning session at the dentist’s,” said the designers, according to Dezeen.

According to some reports, by eliminating the need for toothpaste, the toothbrush’s creators want to help you save money and reduce the amount of waste you produce.

However, that’s unlikely, since the toothbrush needs to be replaced on a monthly basis. Furthermore, ‘Misoka’ actually means ‘the last day of the month’.

There’s no word yet on how users should go about trying to recreate that minty-fresh feeling.

The toothbrush has actually been available for purchase in parts of Asia since 2007, but Ueshima and Yumeshkunin wanted to develop it further and introduce it to the European market.
