FLUORIDE TOOTHPASTE:
IS IT HARMFUL TO THE
HUMAN BODY?
In the 1930's, an American
dental specialist had discovered
that, among 5,831 children in 22
cities, the fluorine content of
drinking water of 1 mg/L appar-
ently protected half of the chil-
dren from dental caries - the
rationale of the policy of fluori-
dat i on of dr i nk i ng water.
However, large numbers of chil-
dren had dental fluorosis - the
teeth were literally mottled
brown with the destruction due
to fluorine. In severe cases,
even other bones may also be
affected, a condition rather simi-
lar to osteoporosis, called "skel-
etal fluorosis" whereby the
bones would become more
brittle than normal. After fluori-
dation of drinking water, fluoride
toothpaste appears to be safer.
China has also become the
world's "Number 1" manufac-
turer of toothpaste and, empha-
sis is, at times, on "double
fluoride". However, even as the
toothpaste is expected to act
locally when brushing teeth, in
youngest children, some tooth-
paste may be swallowed inad-
vertently - a realistic cause of
fluorosis even if the fluorine in
drinking water is low. Be sure
that just "pea-sized" toothpaste
of preferably a low-fluoride con-
tent toothpaste is used for these
very young children.
