There are a lot of recipes in the internet of homemade toothpastes (see this link or this link as examples).
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.
