Self-powered toothbrush uses mild electric shocks to target plaque bacteria
Researchers have developed a self-powered toothbrush to tackle bacteria that can remain after brushing.
It converts brushing friction into electricity with each stroke.
The charge is intended to give plaque-promoting bacteria mild electric shocks and stop them colonizing teeth.
Bacteria can rebuild plaque within hours of brushing.
Conventional toothbrushes rely on scrubbing, while some of the remaining microbes are linked to cavities and gum disease.
The researchers’ approach could offer another way to fight these microbes, but no further steps or timeline are given.
