How can Sodium Fluoride Ion solve the issue “cavity” In this essay, I will explore about how sodium fluoride ion can be addressed to one of the most common health issues in the world “cavity” by investigating the properties of sodium fluoride ion and how those properties of sodium fluoride ion are related to addressing this issue. Sodium Fluoride ion is an ionized combustion of non-metal atom Fluorine and alkaline metal sodium as you can notice from its name, and its scientific equation is NaF. In nature a singular fluorine cannot be easily found, according to “How does the fluoride in toothpaste prevent cavities? Is there any kind of 'natural' fluoride protection or is it only in artificial compounds?” by “SCIENTIFIC AMERICAN” “Fluorine, the 13th most abundant element in the earth's crust, is never encountered in its free …show more content…
It exists only in combination with other elements as a fluoride compound.” (Scientific American, 2013) which means Sodium Fluoride is possible to be made from nature not only made in an artificial way. Because of rocks under the ground always touch with water many of sodium fluoride found in nature is already ionized. And Sodium Fluoride ion is toxic to the human body if you take it too much. According to “Sodium fluoride (NaF) causes toxic effects on splenic development in mice” by “Pin Kuang” ”Other studies have also shown the fluoride-caused cytotoxicity, apoptosis and DNA damage in human” (Kuang, 2017) which means fluoride is toxic for a human being. This polyatomic ion is commonly used for protecting teeth from cavity because it can react with the ingredient of teeth enamel “hydroxyapatite” and makes tooth enamel stronger so that teeth can get higher acid resistance. There are also other usages of Sodium Fluoride Ion, for example, because of its toxicity it is used to make rat poison. So sodium fluoride ion is an ionized
