A charcoal toothbrush has bristles that are infused with activated charcoal. The toothbrush bristles are slim and tapered, allowing for deep yet gentle cleaning. If your charcoal toothbrush also has a cheek and tongue cleaner, it can help to remove odour-causing bacteria.

The difference between a regular toothbrush and a toothbrush with charcoal is that the latter features bristles infused with charcoal. Charcoal bristles may be effective in helping to remove light surface stains.

Charcoal toothbrushes may be effective at helping to remove light surface stains, as charcoal is known to absorb and bind to impurities well. If you’re wondering how to fix yellow teeth staining, try a charcoal toothbrush combined with a whitening toothpaste.
