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 beverages, although quantities vary considerably from region to region,
The importance of fluoride for tooth development has been well documented in children living in the areas of naturally occurring fluoridate water had superior dental health to children living in areas where the water was relatively deficient in this element. In fluoride-deficient regions this element can be added to the water supply in minute quantities.
When this is done, the benefits in improved dental health in the population exposed to fluoride-supplemented water are similar to those obtained by exposure to fluoride occurring naturally, In either case, researchers have observed the preventative effects working through various mechanisms, chief among which are that fluoride reduces the solubility of tooth enamel and also reduces the ability of plaque organisms to produce enamel-attacking acids. During the formation of teeth in the young, fluoride joins with the enamel surface and makes it harder and hence more resistant to decay.
According to research, fluoride can even help repair cavities by rebuilding the enamel layer of teeth. Topical application by way of fluoride toothpaste or drops is also helpful in older adults since it can help prevent decay and sensitivity in the roots of teeth.
The sources describe about the relationship between the use of fluoride and dental health. The passage argues that fluoride is necessary to improve dental health. The professor, however, sees fluoride supplementation much differently. She concerned with the absence of public consent about the fluoride supplementation, and then she supported her view with the new studies describing the potential dangers of fluoride.
The passage tells about the fluoride supplementation in some areas with low fluoride. However, the professor denied this process because the public didn’t receive prior information or knowledge about such process. She argued that the public deserves to acquire sufficient information about the potential risks or dangers of this process.
Moreover, the passage describes that fluoride is important to improve dental health, such as preventing from decay and enamel damage. Meanwhile, the professor brings some new researches that undermine this argument. First, it shows that average decay rates between children in high fluoride and non-fluorided areas are identical. Additionally, trend of decay rates decreases due to some other unconnected factors. Second, fluoride is not environmental-friendly for some reasons. It contains pollutants and toxic that would result an unforeseen health problem. Furthermore, negative side effects of fluoride have been found in animal testing.
In conclusion, some new studies introduced by the professor contradicts the points made in the passage, which is about the importance of fluoride in improving dental health. According to the professor, further study and debates about the benefit and potential dangers of fluoride needs to be carefully examined.
