My plan will be to still use like Crest or something with flouride. I've been using flouride based toothpastes for years and haven't had cancer yet. I think you still need some flouride to fight cavities. I have tried numerous brands of health food stores toothpastes and powders and still have plaque building up. I'm also going to remineralize my teeth with ACT mouthwash and Zellies xylitol gum. Plus I'm taking my calcium for healthy teeth and bones.
