Product descriptions commonly specify activated charcoal, frequently sourced from coconut shells (listed as coconut charcoal or activated coconut charcoal). Some listings also refer to activated or 'white' charcoal; exact source varies by brand.

Typical instructions are to wet your toothbrush or apply a small pinch of powder to your palm, dip the damp brush into the powder, and brush gently—many listings advise brushing for about two minutes. Use only a small amount to reduce mess and follow the product’s own directions.

Common flavorings and essential oils listed include peppermint, grapefruit, and lemon. Peppermint is frequently used for a fresh taste.

Some listings advertise 'less mess' packaging or include practical advice such as using a small spoon, applying only a small amount to the brush or palm, and opening jars with care to avoid powder dispersion. Check individual product descriptions for any mess-reducing design details.

Some product bundles include extras such as a bamboo toothbrush, a whitening tray/unit, or a whitening rinse alongside the charcoal powder. Extras vary by seller and listing.
