Research shows that charcoal toothbrushes may have some beneficial uses. They may be able to whiten teeth, reduce bad breath, and remove bacteria better than most traditional toothbrushes. Most bad breath is caused by bacteria on your teeth and tongue. So, reducing bacteria in your mouth can help keep your breath fresh. Activated Charcoal (AC) toothbrushes may be effective at lowering bacteria. A 2018 study specifically on charcoal-infused toothbrushes found they are effective at lowering levels of bacteria. In the study, after use, the toothbrush bristles contained significantly fewer bacteria than regular toothbrushes used by the same people for the same amount of time. You still need toothpaste, the bristles are just infused with charcoal to provide extra cleaning/whitening. VELYM Toothbrush is available in two colours – blue and pink. The toothbrush is recommended for use in rotational movements then the bristles fit perfectly between the teeth and clean them.
