Fluoride is a natural mineral found in various foods and water sources. It is well-known for its ability to strengthen tooth enamel, making it an essential component in preventing cavities. Many dental products, like toothpaste and mouth rinses, contain fluoride to help maintain oral health. In addition to its dental benefits, fluoride is often added to community water supplies to promote public health. This practice, known as water fluoridation, has been endorsed by organizations like the World Health Organization for its effectiveness in reducing tooth decay, especially in children.
