Sources of topical fluoride include:

Sources of topical fluoride include:

• A. Fluoride toothpastes
• B. Water fluoridation
• C. Fluoride varnish
• D. All of the above

Answer: (D)

Topical fluoride helps protect teeth when fluoride is present directly on the tooth surfaces. Fluoride toothpaste delivers fluoride every time you brush, creating a fluoride-rich layer on enamel that reduces demineralization and promotes remineralization. Fluoride varnish provides a professional, high-concentration topical fluoride coating that stays on the teeth long enough to enhance remineralization and inhibit caries progression. Water fluoridation adds fluoride to drinking water, and while its most noticeable benefit is systemic, the fluoride it provides is also present in saliva and plaque, giving ongoing topical protection at the tooth surfaces. Because each option delivers fluoride to the mouth to act on the teeth, all of the above are sources of topical fluoride.
