Quick Summary
Researchers have developed a teeth-whitening powder that works with the vibrations of an electric toothbrush to safely remove stains. Unlike traditional whiteners, it not only brightens teeth but also repairs enamel and supports healthy oral bacteria. Lab tests showed dramatic whitening effects, while animal studies revealed reduced harmful microbes and inflammation. This could pave the way for a new generation of at-home dental care.
