Fluoride is not a man-made medicine. Rather, it is a mineral that can be found in different amounts in water. It is proven to help protect against tooth decay. Fluoride keeps the enamel of your teeth strong by re-mineralization. According to the American Academy of Pediatrics optimal exposure to fluoride is important to infants and children. The use of fluoride for the prevention of dental caries is safe and effective. It is recommended that parents consider using dietary fluoride supplements for children at risk for dental decay if their water is not fluoridated. Professional applications are recommended at least every 6 months or more often if your child has a high caries risk.
