Explain the relationship between fluoride and oral health
What will be an ideal response?
When consumed in optimal amounts, fluoride enhances tooth and bone health. As a combination from the water and food supply, in addition to topically in the form of toothpastes, rinses, and office treatments, fluoride has been shown to reduce the risk and prevalence of dental caries. Excess fluoride intake while teeth are developing can result in enamel fluorosis caused by the disruption of enamel formation. This can lead to the presence of irregularly distributed patches in tooth enamel that can range from chalky white to yellow, to gray, and even to brown or black.
