Yes, I've used the toothpaste Dioxi Brite and it does everything it says it does. My dentist was amazed. My tongue always had a thick coating of white yeast (?) on it, not anymore, it's now pink. My teeth always had a thin layer of biofilm in the morning, and now they don't. I always had a lot of plaque, now I have a little tiny bit on the backside of my front teeth.
I also bought the shampoo and no more dandruff and it makes my hair very soft.
