What is is? Whitening powders typically use abrasives to scrub away surface stains which can lead to things like enamel etching and sensitivity. Instead of an abrasive whitening method, the PAP+ Powder oxidises stains through the use of PAP (Phthalimidoperoxycaproic Acid) without causing any pain or sensitivity. Add effective whitening to your everyday toothpaste by simply dipping it in the PAP+ Powder.
