Prompt- Research an everyday product or phenomenon that involves chemistry, explain the chemical processes behind it, its practical uses, benefits and drawbacks, and include at least two credible sources.

An everyday product that involves chemistry is toothpaste. One of the main ingredients used in most toothpastes is Fluorine. Fluorine is used in toothpaste because it strengthens your enamel and repels cavities. Bacterias in your mouth create an acid which breaks down the minerals on your tooth’s surface, making it more susceptible to cavities and decay. (CDC.gov) Fluoride replenishes these minerals that were lost so your teeth can stay healthy and clean. 

While Fluoride is extremely useful for dental health, many professionals advise that it is used in small doses. According to the Yale School of Public Health, “While the benefits of fluoride are clear, prolonged exposure to high levels of fluoride can be harmful to teeth and bones (known as fluorosis), which includes causing discoloration, spots, or damage to teeth and bone fractures.” Thankfully, toothpaste does not contain enough Fluoride to be harmful when used correctly. The average toothpaste contains anywhere from 1000 to 5000 ppm (parts per million) of Flouride, but there is only about 0.75 mg in one serving.

Fluorine is an element that can be extremely beneficial when used in safe amounts, and it is crucial that we continue to safely consume it when instructed.
