For half a century, controversy has surrounded the way that fluoride compounds reduce the risk of tooth decay, in spite of extensive scientific research. Now, recent studies have confirmed that fluoride penetrates and hardens a thin layer of enamel, and the latest report describes evidence showing that fluoride also works by reducing bacteria?s adhesion, making it difficult to stick to teeth and produce cavity-causing acid.
All in all, the study shows that fluoride reduces the ability of decay-causing bacteria to cling to teeth, making it easier to rinse away potential cavity causers with saliva, brushing teeth, or using mouthwash.
