Say goodbye to toothpaste!
Designer Kosho Ueshima collaborated with Japanese technology company Yumeshokunin to create an incredible toothbrush that uses nanotechnology to clean your teeth—no toothpaste necessary. The brush’s bristles—which are 0.178 millimeters thick—are coated in mineral ions, and when passed over your teeth, the ions remove stains and form a protective coating over your enamel. To activate the brush, all that’s needed is a dip in a cup of water.
“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,” the designers told Dezeen. Meant to resemble a stream of running water, the brush is named Misoka, which means “last day of the month,” in Japanese. That also happens to be the lifespan of these brushes, requiring a change of bristles every 30 days.
