The fact of the matter is that fluoride is a toxic substance with no known biological imperative. Researchers have even questioned its efficacy as a topical anticaries prophylactic.3
Dental caries is caused by demineralization of your teeth by the acids formed during the bacterial fermentation of dietary sugars. Demineralization is countered by the deposit of minerals from your saliva. However, the remineralization process is a slow one, and fluoride is said to prevent dental caries by enhancing this remineralization.
The problem is, your teeth do not actually rely on fluoride for remineralization. What’s more, research4has concluded that the protective shield fluoride forms on teeth is up to 100 times thinner than previously believed. It has long been believed that fluoride changes the main mineral in tooth enamel, hydroxyapatite, into a more-decay resistant material called fluorapatite....read more>>>...
