Powdered activated carbon is sanitizing for teeth. In our mouth, activated carbon is almost like a clay mask for the skin: it attracts organic micro-residues to it, like a sponge. It thus captures its micro-residues that can lodge in dental interstices. Powdered activated carbon not only whitens teeth, it is above all a powerful sanitizer, beneficial for the gums and all oral hygiene. It regulates the pH of the mouth, and thus defends us against various bacteria that could lead to caries. It is alkalizing and therefore helps us fight against acidic PH, especially generated by sugars. Tip: Use your homemade toothpaste and rub in the powdered activated carbon for best results.
