Fluoridation of Table Salt
The following Question and Answer was published in the
Journal of the American Dental Association Vol. 44 (1952) on page
FLUORIDE IN TABLE SALT
To the editor: - Would it not be less wasteful to put fluorine in
minute amounts in our table salt, as has been done with iodine, than to put
it in the water supply? Such a small quantity of the water in the mains ever
reaches a person´s digestive tract, but most of the salt in salt shakers
Z.F. Endress, M.D., Pontiac, Mich.
Answer: - Caries inhibtion by fluoride (about 1 ppm of fluorine) in
drinking water has been studied in great detail. No comparable information
is available for judging the effect of fluoride added to table salt. The
known variations in the consumption of salt by different persons suggests
that the latter procedure would not be satisfactory. Furthermore, many
drinking waters naturally contain adequate fluoride, and the use of a fluoridized
salt would be undesirable in these cases. It is more logical to add iodine
to salt, because iodides have a much wider margin of safety than do
fluorides. The wastefulness of adding fluoride to a water supply is more
apparent than real. The added materials are readily available and inexpensive,
and also the labor involved in a carefully controlled program is negligible
when computed in terms of the individual child.

Isn´t that amazing?
