Fluoride Is Key Tooth decay is the breakdown, or destruction, of tooth enamel. Enamel is the hard outer surface of a tooth. Tooth decay can lead to cavities (caries). These are holes in the teeth. You can help prevent tooth decay: Start brushing your child’s teeth as soon as the first one appears. Brush the teeth, tongue, and gums twice a day with a fluoride toothpaste. (Or watch as your child brushes his or her teeth.) •But using toothpaste with fluoride is the key ingredient for strengthening tooth enamel to prevent tooth decay. #bestdentistnearme #bestspringvilledentist #bestutahvalleydentist
