What does Systemic fluoridation mean?

• A. Fluoride is swallowed, circulates through the body, and becomes part of the developing tooth structure before eruption
• B. Fluoride is applied topically after eruption
• C. Fluoride is not absorbed by the body
• D. Fluoride is applied as paste to teeth after eruption

Answer: (A)

Systemic fluoridation means fluoride is ingested and becomes part of the bloodstream, which carries it to developing tooth structures. As teeth form in the jaw, fluoride is incorporated into the enamel and dentin before eruption, making the teeth more resistant to acid attacks once they emerge. This pre-eruptive incorporation is why swallowing fluoride, whether through fluoridated water, supplements, or certain foods, benefits the teeth during development. In contrast, topical fluoride is applied directly to teeth after eruption to strengthen enamel from the outside, and fluoride that is not absorbed is inaccurate because fluoride is absorbed and utilized in the body. Applying fluoride as a paste after eruption is a topical method, not systemic.
