Most of the recipes remark the benefits of using these toothpastes to promote remineralization. I've just started trying on of these clay-based toothpastes and I was wondering two things.
First, are they as effective in terms of dental hygiene a industrial toothpastes?
Second, are there any health hazards regarding this toothpastes?
P.S. I don't know if I should post this as one or two different questions.
