Fluoride has become a popular topic lately with the Cairns Regional Council making the decision to stop adding chemical fluoride into the water supply in Cairns and surrounds.  People are asking for this product to replace the fluoride in the water for the health aspect for their children’s teeth.  However, this is a S7 toxic poison so can’t be supplied as a supplement.  

Hydrofluorosilicic acid and sodium silicofluoride are collectively known as the silicofluorides and are the chemicals used most in Australian states fluoridation schemes. These are industrial grade waste from phosphate fertilizer manufacture, not pharmaceutical grade products.  The Material Safety Data Sheet relative to Incitec Pivot Limited, the Fertiliser Company that provides “fluoride” to Australia Water supply transports this chemical as an S7 Dangerous Poison under the Australian Dangerous Goods Code. 

(Schedule 7. Dangerous Poison – Substances with a high potential for causing harm at low exposure and which require special precautions during manufacture, handling or use. These poisons should be available only to specialised or authorised users who have the skills necessary to handle them safely. Special regulations restricting their availability, possession, storage or use may apply.)

             The Ecotoxicological information on this data sheet states “avoid contaminating waterways, toxic to aquatic organisms.

For those wishing to use fluoride to strengthen tooth enamel, the best way is to use toothpastes which contain pharmaceutical grade sodium fluoride, not the S7 poison that is added to water supplies and which subsequently enters our waterways.

The natural mineral Calcium Fluoride (Calc Fluor) is an important mineral found in bones, skin and teeth and is used to strengthen tendons, muscle tone and especially connective tissue. These supplements are inexpensive and available in most pharmacies and health food stores.  It is available in the form of cell or tissue salts, a white tablet which is dissolved in the mouth. It works by bonding calcium from the saliva to the enamel of the teeth. This form of fluoride can be used without mottling and darkening of the teeth.

As most tooth decay is generated by sugars in drinks and foods, not enough calcium rich green vegetables and poor mouth hygiene it is recommended that these areas of health care be implemented to preserve teeth ahead of fluoridation by water, toothpaste or supplementation.
