The Colgate Slim Soft Charcoal toothbrush with 17x thinner bristles at the tip compared to regular rounded bristles provides a deep but gentle cleaning of the mouth. Thinner bristle tips help clean between teeth and along the gum line. Charcoal-infused bristles sweep away food and grime, leaving your mouth feeling cleaner with every brush. The toothbrush also comes with a slim rubber handle that offers comfortable brushing. Colgate Slim Soft Charcoal has 17x bristles with slimmer tips (versus regular rounded bristles) that are specially designed to remove food and plaque along the gum line and narrow spaces between teeth. The soft bristles clean deep between the teeth and behind the teeth, reach places where ordinary bristles cannot reach and effectively remove bacteria. Its extra soft charcoal infused bristles remove plaque bacteria. Colgate is the #1 toothbrush brand recommended by dentists.
