The Goodbrush Sonic Toothbrush brightens teeth via ACP (Active Charcoal Polishing) technology and hydrodynamic non-contact cleaning. Instead of packing bleach and abrasives into a toothpaste, Goodbrush puts it into the bristles where it acts more gently, but just as efficiently.
The iconic black bristles of the Sonic Goodbrush contain tiny particles of activated charcoal. The charcoal particles of the ACP technology have a dual-effect similar to the two-in-one cleaning action of kitchen sponges. Imagine that one side has a gentle, non-abrasive pad for mechanical cleaning and loosening tough stains and the other has a soft and porous sponge for absorbing stain-causing substances and residual food. Aided by the hydrodynamic sonic power, the pad gently scrubs away at stubborn stains and plaque. Once loosened, the residue is absorbed by the spongy side of the charcoal particles, revealing your naturally white and polished smile.
