"the widespread use of low-fluoride children’s
toothpastes in Australia, which has markedly reduced
the prevalence of dental fluorosis (mottling of tooth
enamel) in Australia (the unavailability of these
toothpastes in the US is a significant reason for the US
proposal to reduce the fluoride level in water fluoridation
programs in the US)"
"Low-fluoride children’s toothpastes
In the early 1990s low-fluoride children’s toothpastes were
introduced in Australia for children aged under six years.3
These were introduced to reduce the prevalence of
dental fluorosis (mottling of tooth enamel), which can
sometimes occur if too much fluoride is ingested.3 Since
their introduction, low-fluoride children’s toothpastes have
significantly reduced the prevalence of dental fluorosis
in Australia, so that now, if dental fluorosis does occur in
Australia, it is almost always very mild or mild.4 Awareness
raising of appropriate toothpaste use by children (using
it under supervision, using a pea-sized amount smeared
over the brush, spitting out and not swallowing) has also
played a part in reducing dental fluorosis in Australia.4
Importantly, these low-fluoride children’s toothpastes
are not available in the US.5 Dental fluorosis is not
a public health issue in Australia because of the
very high proportion of children using low-fluoride
children’s toothpastes.4"
"High naturally occurring fluorides in some
US water supplies
All water supplies contain some natural fluoride.6
In Australia most water supplies have low levels of
natural fluoride that do not confer dental health benefits.7
In the US, however, a small but significant number of
people consume water that is naturally highly fluoridated8 –
sometimes several times the level used in water fluoridation
programs in Australia.
The low levels of fluoride in Australian drinking water
supplies is another reason why dental fluorosis is not
a public health issue in Australia."
"fluorosis, it is important to note
that studies reveal that development of dental fluorosis
is more closely related to fluoride toothpaste and tooth
brushing practices than to water fluoridation.14,15 In other
words it is more important to address toothpaste and
tooth brushing issues, rather than reducing fluoride
concentration in water fluoridation programs, in order
to tackle a reported increase in dental fluorosis."
