To achieve a brighter smile, Colgate recommends using their Colgate Activated Charcoal Medium Toothbrush. The micro-fine bristles are enriched with activated charcoal and get deep between your teeth for a more thorough clean than a manual toothbrush with a flat bristle field - up to 2x better. In addition, this toothbrush is also equipped with a tongue cleaner, which reduces unpleasant odours in the mouth and gives you a fresher feeling. Thanks to the ergonomic handle, you can clean effortlessly and look forward to your brightest smile.
