The safest way to clean teeth for those most sensitive to chemicals
is with pure baking soda, pure sea salt, or a combination of the
two. Sensodyne toothpaste is corn-free and can be tolerate by
some people who cannot use other toothpastes.
Formula for
tooth powder: In a blender, whip until pulverized, 3/4 cup of
salt. Add 3/4 cup baking soda. Blend until reduced to a
very fine powder. Optionally, add one herb for flavoring, such as
cassia or mint.
