Fluoride is one of the most effective ways to prevent tooth decay. Fluoride is a mineral that occurs naturally in almost all foods and in water supplies such as rivers, lakes, wells and even oceans. Fluoride is the thirteenth most abundant element in the world and makes up 0.08% of the Earth's crust (Awofeso an Peckham 2014). After tooth eruption, fluoride helps remineralize weakened tooth enamel and reverses early signs of dental decay. More than 70 years of scientific research have consistently shown that an optimal level of fluoride in community water is safe and effective in preventing tooth decay by at least 25% in both children and adults (ADA). Water fluoridation reaches everyone in the community and has a wide range of benefits. Water fluoridation is also very economical and effective. Say no to plagiarism.

Before water fluoridation, children had about three times the number of cavities. Because of the important role it has played in reducing tooth decay, the Centers for Disease Control and Prevention proclaimed community water fluoridation one of the Ten Great Public Health Achievements of the 20th Century (ADA). Today, nearly 75% of the U.S. population is served by fluoridated community water systems. Researchers have shown that there are several ways in which fluoride achieves its decay-preventing effects. It makes the tooth structure stronger, so the teeth are more resistant to acid attack. The acid is formed when bacteria in plaque break down sugars and carbohydrates in the diet. Numerous acid attacks tear the tooth apart, causing tooth decay. Fluoride is necessary for ideal oral health for all ages. Fluoride also works in repairing areas where acid attacks have already started. The remineralizing effect of fluoride is important because it reverses the process of early tooth decay and creates a tooth surface that is more resistant to tooth decay. The most effective way to treat a community with fluoride is through water fluoridation. Protection from fluoridation reaches people in their homes, at work and at school simply by drinking the water. Water fluoridation is supported by organizers such as the American Dental Association, the American Medical Association and the World Health Organization. Please note: this is just an example.

Too high fluoride levels in water supplies can cause health problems, which is why the EPA established the water fluoridation standard. The Safe Drinking Water Act was passed by Congress in 1974. The EPA is required by law to evaluate the level of contaminants at which drinking water will be safe and will not cause adverse health effects.
