The decision to
make District Health Boards, not local councils, responsible for fluoridation
is an obvious one, and seems to have been well received.
Currently, just
over half our population, about 2.4 million people, live in areas where the
water supply is fluoridated. Shifting the responsibility to District Health
Boards, and assuming all agree to fluoridate the water supply in their areas,
will add up to another 1.4 million people to the numbers of those receiving fluoridated
water.
The fluoride
debate has been controversial for years, with no government until now prepared
to advance it. At the same time, over all those years, the oral health of young
New Zealanders, in particular, has steadily declined. A big capital investment
in new oral health centres and mobile clinics over the last decade has started
to redress the balance somewhat, but there is still a long way to go.
Although the
fluoride debate has been controversial and the opposition vocal in some
quarters, public opinion has been consistently, albeit narrowly, supportive of
fluoridation. In recent years, efforts by anti-fluoride campaigners to force
local polls have been persistent, and this has forced some councils into
awkward situations. The recent example of the Whakatane District Council voting
narrowly to end fluoridation at one meeting, and then voting narrowly to
overturn that decision and retain the status quo at its next meeting, and the
about-face of the Hamilton City Council before and after the last local
government elections have been quite unedifying.
Local Government
New Zealand rightly points out that local authorities are being placed in an
impossible situation, especially since their only real involvement is to own
the pipes through which fluoridated water is reticulated. But there are
realistically only two alternatives to the current situation, assuming of
course the national preference is to retain fluoridation. One option would be
for central government to simply mandate that all water supplies are to be
fluoridated forthwith, but this would be remarkably heavy-handed, and would
shut out any capacity for people to have their say. The second alternative, and
the one settled upon, is to shift the responsibility for deciding whether or
not an area is to be fluoridated to the local District Health Board.
There are 20
District Health Boards across New Zealand, which immediately reduces the
potential for inconsistent outcomes, given that there are a far greater number
of local councils. Also, oral health (and fluoridation) is primarily a public
health issue, and District Health Boards have the statutory responsibility for
the promotion of the public health in their areas. So it is logical that they
take responsibility for fluoridation policies.
However, it would
be wrong to see fluoridation as a panacea for the oral health of New
Zealanders. It is certainly an important step, but by no means the only one. It
needs to be accompanied by other measures such as good oral health education
for children, the promotion of healthy drinks like water, and encouraging good
health generally.
The fluoridation
decision nevertheless marks an important step forward in the campaign for
better oral health for all New Zealanders. It will have a beneficial impact and
is arguably the single most important move to be taken to secure good oral
health for current and future generations.
