Tooth decay, or cavities, used to be a certainty. But the arrival of fluoridated drinking water and toothpaste has changed that. Fluoride is a natural mineral that safely strengthens tooth enamel (the hard outer "shell" of your tooth) and helps stop cavities from forming.
Children can really benefit from fluoride. In fact, in communities where fluoride has been added to the drinking water, children have up to 50 percent fewer cavities!
If your child isn’t getting enough fluoride from the drinking water, or they continue to get cavities, your dental professional may suggest a fluoride treatment.
