An alternative to fluoride
An alternative to fluoride
22nd Jan 2010
For decades, oral healthcare has been focused on the effects of fluoride and how it prevents enamel demineralisation caused by acidic food, drink and plaque because it helps to reinforce and strengthen enamel.
This is because when fluoride interacts with enamel hydroxyapatite, it results in fluorapatite, which is less soluble and more mechanically resistant.
Indeed, much scientific evidence supports the positive effect that fluoride has on oral health, and subsequently a lot of oral care products containing fluoride have been patented. In some countries, drinking water has also been enriched with fluoride.
However, fluoride is not essential for human growth and its content in the body is not under physiological control. Once absorbed, for example, fluoride is rapidly distributed throughout the body and is retained only in calcified tissues. As a result, dangerous health conditions have been linked to the daily intake of fluoride and many studies have proven that there are actually high risks associated with fluoride, in particular for children (fluorosis) and for old people (bone disease).
Despite these findings, fluoride continues to be widely used in oral care products to prevent enamel surface demineralisation .................................
