What's behind that confident smile? The Tom's of Maine Gentle Charcoal Toothbrush. The charcoal-infused bristles are two times softer than an ordinary flat trim toothbrush, so this ultra soft toothbrush can effectively remove surface stains and clean teeth while being gentle on gums. Plus, each handle is made from 5% post-consumer recycled plastic, and the ultra soft bristles are BPA-free — so you can brush with the best. When those bristles start to wear, you can take this recyclable toothbrush to your nearest Tom's of Maine TerraCycle collection program.
