The use of fluoride in preventative dentistry has been a great breakthrough in improving the dental health of large populations. Small amounts of soluble fluoride ions are present in all water sources, including oceans and also to some extent in food and

The reading and lecture are both about the fluoride supplementation in the water to improve the dental health. The author of the reading of the reading feels that it is beneficial to fluoride in water. The lecturer challenges the claims made by the author. he is of the opinion that fluoride is a toxic substance and can possess health risk associated with it. To begin with, the author argues that the mixing of fluoride is a old process as it has been carefully documented. The article mentions that the written manuals show how by adding fluoride to the water of fluoride deficient regions has helped improving the dental health of the children in that area. this specific argument is challenged by the lecturer. she claims that as the supplement is hazardous public consent is necessary< span class=" hiddenGrammarError" pre=" who " > < /span> . Additionally, she terms the entire procedure as a vast experiment where the people are the guinea pigs. Secondly, the writer suggests that dissolving fluoride has some additional benefits as well. In the article, it is said that fluoride is reducing the solubility of tooth enamel and making the plaque organisms inept to make acids. The lecturer, however, rebut this by mentioning that regions with fluoride mixed in water to the regions with fluoride naturally occurring have identical average decay rate. he elaborates on this by bringing up the point that something other than fluoride is responsible for the dental health. Finally, the author posits that fluoride is also help filling the cavities by rebuilding the enamel. Moreover, in the article it is stated that toothpaste mixed fluoride can help adults by making their teeth resistance to sensitivity and decay. In contrast, the lecturer's position is that fluoride added to the water is not a natural component and thus, a poison. he notes that, the artificial supplement is derived from toxic wastes and pollutants which can cause severe side-effects to the humans. Therefore, a public debate is necessary to reach a final conclusion and make people aware of the paradox.
