This fine, natural and non-toxic powder works by absorbing and polishing away stains and plaque that naturally form on our teeth. It's a completely safe and fast-effective formula made without the use of any chemicals like peroxides, fluoride compounds or synthetic flavourings. We blend together a fine pharmaceutical activated charcoal and sodium bicarbonate both of which food grade, so completely safe if accidentally ingested. Use once or twice a week to maintain your naturally white teeth.
