Both bamboo charcoal tooth powder and PAP+ tooth powder can be used to whiten teeth, but the principles of the two are not quite the same. Bamboo charcoal tooth powder is used to clean your teeth by absorbing the dirt on your teeth through bamboo charcoal. PAP+ tooth powder is used to whiten teeth through PAP(Phthalimidoperoxycaproic Acid), an effective whitening ingredient. It is a chemical tooth bleaching.
For brands that emphasize natural ingredients, bamboo charcoal tooth powder is the better product. But if your brand emphasizes whitening effect, then PAP+ tooth powder is better.
