Hiya guys,
I'm a dentist, and 18 months down the line, most of us are STILL fighting for this fluoride move...this is as much as I know at the moment...
There ARE areas within the UK (and other parts of the world I expect) which have NATURAL fluoride in the tap water supply. There are ALSO areas within the UK (and again, other parts of the world) which have fluoridated tap water (such as Birmingham) - I grew up in an area which was fluoridated, but has since withdrawn it. It is a COMPLETELY political issue, which brings along with it some litigation issues, due to the water companies not wanting to be held responsible for anything . Up to date...the government have stated that they will deal with any future litigation issues, which leaves the water boards to decide whether they put fluoride into our water, as long as they liase with the local councils etc. What the government HAVEN'T stated (yet) is how this public contact will take place etc... So I haven't heard of anything positive come out of it yet...but if (most) dentists have their way, there should be one day...maybe... In my opinion, something that's keeping the public from fighting for it with us, is lack of education...which again, in my opinion, should be tackled first.
Fishwise, I must admit that I don't have any sound evidence either way...but knowing that there IS fluoride in some UK areas, and in other countries, I can't imagine it's very harmful for them at all. After all, we're talking about a MINUTE amount of it.
That's as simple as I can put it...there are a lot of other issues, but I won't go into them...unless you ask me too!
