Fluoridation Water Fights Tooth Decay SCH3U1-04 Minjae.Kim In 1945, Ontario became the first province in Canada to add fluoride to community water supplies. The idea of ​​fluoridated water can help prevent cavities and tooth decay; however it was the first time in Canada to provide community water containing fluoride. Human teeth are the hardest substance in the human body and 96% of them are made up of minerals called hydroxyapatite (Ca5(PO4)3OH) and when it meets any acids, it will react with it and calcium acid, phosphoric acid and water will be produced. Acids are fatal to the enamel that forms on human teeth and this causes tooth decay. However, when hydroxyapatite meets fluorine, the single shift occurs and fluorapatite (Ca5(PO4)3F) and hydroxide (aqueous) will be produced. This fluorapatite product can protect enamel from acid attack, which means it fights cavities and tooth decay. Here's how fluoridated water can help fight cavities and tooth decay. Today, fluoride can easily be found in people's lives, because it prevents tooth decay and tooth decay. Most toothpaste companies add small amounts of fluoride to toothpastes to protect consumers' teeth. Also, as mentioned above, it is found in the water that people drink every day. Most Canadians drink fluoridated water, with the exception of a few provinces. Finally, fluoride is found in gels and varnishes which are professional fluoride products. Dentists sometimes recommend them to patients, so fluoride can protect patients' enamel. These are the products where people can find fluoride in their life. There are... middle of the paper... fluoride added with water in their products. However, the downsides of fluoride have been discovered and it has been realized that some customers are looking for fluoride-free water, because people with young children do not want their children to drink fluoridated water and end up with fluorosis. They therefore do not want to feed their children tap water, because it still contains fluoride, and look for fluoride-free bottled water. Therefore the industries that produce fluoride-free water have made a lot of money. The government also uses fluoride waste from aluminum factories or other factories that produce fluoride waste to fluoridate water supplies. As a result, factories don't have to worry about their fluoride waste and end up saving a great deal of money. This is the connection between fluoridated water and industry.
