This fine, natural and non-toxic whitening powder works by absorbing and polishing away plaque and stains that naturally form on our teeth. It's a completely safe and fast-effective formula made without the use of chemicals like peroxides, fluoride compounds or synthetic flavourings. We blend two of the most effective and natural whitening agents - fine pharmaceutical grade sodium bicarbonate and magnesium carbonate - which are both also food grade, making them completely safe if accidentally ingested. Use daily as a replacement of toothpaste to maintain your naturally white teeth.
