Unfortunately calcium fluoride is NOT the form of fluoride which is added to Qld water (or in other states in Australia or the USA or in a literal handful of other countries around the world). The "fluoride" added to our water is either sodium fluoride (used as a rat poison), sodium hexafluorosilicate and fluorosilacic acid - which are waste products of fertiliser and aluminium smelting and extremely toxic poisons... Hence not all "fluoride" is the same, or safe to ingest.
Some other facts about fluoride which the government or medical authorities won't tell you:
1) One of the world's most prestigious medical journals, The Lancet, published a study in 2014 which concluded that fluoride was one of several industrial chemicals which are neurotoxins (ie, toxic to the brain). In this study, neurotoxins like fluoride were said to cause developmental delays in children, and are linked to and increased risk of autism, ADHD, and other cognitive issues.
2) Other studies on fluoride have shown that children exposed to fluoride in their drinking water have a lower IQ.
3) Despite the Qld government's decision to fluoridate water supplies in 2007, only one-third of Qld councils are doing so, as many have reversed their decision and stopped fluoridation, after researching the issue more.
4) Water fluoridation has been shown in published research in 2015 to cause thyroid and parathyroid dysfunction including hypothyroidism (low thyroid function, which leads to low body temperature, reduced metabolism, fatigue and weight gain), reduced immune system function, increased inflammation, and other health conditions.
5) Some types of fluoride used in public water have been shown in research in 2011 to cause cancer, especially bone cancer in teenage boys and thyroid cancer.
6) Excessive fluoridation can cause fluorosis in teeth, which is a mottling discolouration with lighter and darker patches. Because fluoride also gets into bones, a similar effect occurs there to cause bone damage.
7) Research from 2011 also suggests that water fluoridation toxicity causes genetic changes in our DNA, which can explain why this leads to cancer and other side effects.
8) Almost all countries in the world do not fluoridate their water, because they are aware of the scientific studies linking the toxic waste product forms of fluoride with a wide range of adverse health effects.
9) Water fluoridation does NOT solve the causes of tooth decay, which are from poor oral hygiene, not brushing teeth correctly or frequently, and a poor diet of too much SUGAR in your food and drinks! Sugar feeds oral bacteria which produce acidic wastes that eat away at your teeth. Better education and public awareness campaigns for oral hygiene will achieve far more benefit and for less cost, and much safer than water fluoridation.
Water fluoridation is an example of government, medical and industry-sponsored mass poisoning of the population. It's about making money for them, as it's not for any health benefit. Luckily there are some things you can do to avoid toxic fluoride - a good quality water filter such as a reverse osmosis filter with specific fluoride filter and remineraliser can remove 99% of fluoride, or some ceramic filters can reduce about 80%. The jug or tap adapter type filters won't remove any fluoride. I'm contacting a couple of water filter suppliers to see what deals they can offer you!
If you don't believe me, please do your own research into what forms of fluoride are added to your water, where they come from and what effects they have on your body, for your health and that of your family. There's tons of published, peer-reviewed research to back this up, and very easy to find - now that you know the forms of fluoride to look for.
