Fluoride is a compound of the element fluorine, which is found universally throughout nature in water, soil, air and in most foods. Fluoride is absorbed easily into the tooth enamel, especially in children’s growing teeth. Once teeth are developed, fluoride makes the entire tooth structure more resistant to decay and promotes remineralization, which aids in repairing early decay before the damage is visible.
In the correct dosage fluoride is beneficial, like many substances that our body requires (such as sodium) a little is good but too much can be detrimental. The correct use of fluoride has given us a significant public health benefit in the prevention of one of the largest childhood diseases: tooth decay.
