How to prevent your child from getting fluorosis

Fluoride is a mineral that helps prevent tooth decay and cavities. Fluoride is added to some water supply, toothpastes, and other mouth care products. It helps repair the early stages of tooth decay even before the decay can be seen, and makes teeth more resistant to the acid attacks that cause cavities.

Brushing with fluoride toothpaste helps prevent cavities and strengthen your teeth's enamel. Normal amounts of fluoride added to public water supplies and bottled water are safe for children and adults, but can be toxic in large amounts.
