White sores on lip and tongue is NOT part of th healing crisis! It is a reaction to too much cheap fillers in the product, and/or too much ac sorbic acid (vit c). So stop all fruits, and also, just to make sure, have you changed your toothpaste recently? Some toothpastes have additives to make them foam which cause cankor sores.
You may want to switch products. Go for something simpler, that jsut has fiber and Bentonite clay. Your body just doesn't like this product. No product is good for absolutely everyone.
