Fluoride application is a preventive dental measure focused on strengthening tooth enamel and preventing tooth decay. This process promotes remineralization, reducing sensitivity and aiding in the repair of early-stage tooth decay. Applied topically in dental offices or included in home care products like toothpaste, fluoride customizes preventive plans based on individual risk factors. Its antimicrobial properties also contribute to preventing and managing gum disease. Whether through professional treatments, community water fluoridation, or daily oral care products, fluoride plays a crucial role in maintaining overall oral health by fortifying enamel and minimizing cavity risk.
