Fluoride Varnish
A high-concentration fluoride preparation painted onto tooth surfaces to prevent or arrest dental caries, recommended at regular intervals in both primary and secondary care.
Full Definition
Fluoride varnish is a resinous agent containing high-concentration fluoride (typically 22,600 ppm as sodium fluoride, e.g., Duraphat) that is applied topically to tooth surfaces. It adheres to enamel for several hours, allowing prolonged fluoride uptake that strengthens enamel and inhibits demineralisation. NICE and Public Health England guidelines recommend fluoride varnish application at least twice yearly for children at risk of caries. Editors should note that fluoride varnish is distinct from fissure sealants and fluoride toothpaste recommendations, and should be recorded as a separate treatment item on NHS claim forms.
Usage
Usage note: Write as two words: 'fluoride varnish'. 'Duraphat' is a brand name and should be capitalised; the generic term 'fluoride varnish' is preferred in clinical policy documents. Editors should not conflate fluoride varnish application with fluoride supplementation (tablets or drops).
