Fluoride 1 article

Fluoride is the fluoride ion present in preventive dental products and, in some settings, community water supplies, where appropriate exposure can reduce caries risk by influencing demineralization and remineralization of tooth mineral. Common dental sources include toothpaste, varnish, gel, foam and mouthrinse. The term describes a chemical ion and preventive mechanism rather than a single product, so concentration, route and frequency matter when balancing effective caries prevention with age-related and exposure-related safety considerations.
