Works great with no harsh chemicals
I have tried a few whitening regimens in my life. They often require strips or equipment that hold chemicals against my teeth, which eventually cause mild pain. This product is different. I followed the clear instructions and used the charcoal floss, which felt great. Then I used a bit too much of the tooth powder and had a mouth full of black charcoal! After I figured out how much to use and brushed for one minute, it felt great. No artificial taste or harsh chemicals. Just clean, bright teeth. Just after one use, my coffee stains were gone.
