Chinese scientists have created a brush that cleans teeth with electric discharges whose bristles are made of polyvinylidene fluoride fibers. When rubbed, they produce a gentle current that kills bacteria and helps remove plaque. In tests, the brush turned out to be 6-10 times more effective than a regular one. They are not saying when it will be available for purchase.
