Fluoride

A naturally occurring mineral (the ionic form of fluorine) found in water, soil, and foods. In dentistry, it is used as a pharmacological agent to strengthen tooth enamel and make it more resistant to acid attacks from bacteria.

Why It Matters

Fluoride is the only agent capable of halting and reversing early tooth decay (White Spot Lesions) through a process called remineralization. It incorporates into the enamel structure to create a harder surface.

Clinical Details

• Mechanism: It converts the tooth's natural Hydroxyapatite crystals into Fluorapatite, which is less soluble in acid and harder to dissolve.
• Application: Topical (toothpaste, varnish) effects are more beneficial for adults than systemic (ingested) fluoride.

FAQ

Is fluoride safe?

Yes, when used in correct dosages. Excess ingestion during childhood tooth development can cause Fluorosis (white specks on teeth), but topical application at the dentist is safe and effective.
