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 reading passage applauds the breakthrough of usage of fluoride in improving dental health problems. On the contrary, the speaker suggests that a cautious approach has to be undertaken in determining the usage of fluoride for dental problems.
Firstly, the author suggests that small amounts of fluoride are present in numerous water bodies. In contrast, the speaker says that the safety of these supplements is highly questionable. There pertains a high level of danger as fluoride also originates from the hazardous waste of industries.
In addition, the author states that studies dating back to 1930s show that children living close to fluoridated water have superior teeth than those not living close to such waters. On the contrary, the speaker puts forth the point of a large-scale study being conducted which suggest that the decay rates are identical. Surprisingly, some areas show that decay rates are even going down.
Thirdly, the author says that fluoride supplemented water has improved the dental health conditions of many people. However, the speaker raises a confounding point that the addition of fluoride in water was being done without the consent of the people. The speaker also suggests that people were being used as lab rats.
Lastly, the author suggests research that can recuperate the cavities of teeth. However, the speaker mentions that fluoride is, in fact, poisonous and extensive usage of it can cause serious health problems. The speaker finally concludes by saying that extensive research needs to be conducted to determine whether fluoride does help in dental problems or it doesn’t.
