With its innovative formula containing Purple Charcoal, the "Purple Toothpaste" helps reduce yellow tones and stains on the teeth. The active components and carbon in the Purple Charcoal toothpaste contribute to restoring the natural whiteness of the teeth. The Active Purple Charcoal tooth powder, on the other hand, helps eliminate surface stains. It prevents substances that cause stains, such as cigarettes, coffee, and tea, from adhering to the tooth surface, resulting in whiter-looking teeth. Additionally, Active Purple Charcoal aids in eliminating bad breath. It destroys bacteria that cause bad odors, giving you a fresher breath.
