Fluoride applications primarily focus on dental health. It is commonly found in toothpaste and mouth rinses, helping to strengthen tooth enamel and prevent cavities. Many communities also add fluoride to their drinking water, a practice known as water fluoridation, which has been shown to reduce tooth decay in the population. In addition to dental care, fluoride is used in some dental treatments, such as professional fluoride varnishes and gels. These treatments are applied by dental professionals to provide extra protection for teeth, especially in children and individuals at higher risk for cavities.
