This toothbrush is the best I've ever had. Initially I liked the softness of the bristles and the size of the head which means I feel like I can clean my tooth thoroughly, getting into tighter spots. Two weeks into using it, my teeth are the cleanest they've been in a long time. The stubborn tartar which has always accumulated behind my front lower teeth, and which the dentist has had to remove for me in the past, has come away. Not sure whether it's because the size of the toothbrush is better for me to manage or whether it's something to do with the charcoal. Whatever it is, I'm a convert. And no more plastic handles and bristles in landfill.
