I love how clean it makes my mouth feel, and i do notice my teeth are whiter after a few uses. I use the powder, then the charcoal toothpaste afterwards with the bamboo toothbrush. Only downfall is the charcoal powder is a little on the messy side but take your time opening and closing the container and you'll be fine.
