ZADI toothpaste is by far Superior to every toothpaste that I have ever used. It is in a class of its OWN. Since using this toothpaste, there's no plaque build-up on my teeth, and my mouth feels fresh and clean throughout the day, no matter what I eat. Amazingly, my salivary glands are working better. I no longer have dry mouth. How INCREDIBLE! Thank you Buy Black Movement for always having the BEST for us.
