This toothpaste is pretty great! I must say at first I was a little hesitant using a black toothpaste. I have been wanting to try activated charcoal and this seemed like the perfect option. Less chemicals than normal toothpastes and has probiotics for healthier teeth! For me personally, I like extreme minty feeling after brushing, this does not leave that however, I have noticed a remarkable difference in how my mouth tastes when I wake up! So while the initial feeling is not as minty, I have better breath after extended times. Does not foam like your typical toothpaste however, you brush in the same way! Excited to see extended results!
