Fluoride varnish is a highly concentrated form of fluoride which is applied to the
tooth's surface, by a dentist, dental hygienist or other health care professional,
as a type of topical fluoride therapy. It is not a permanent varnish but due to
its adherent nature it is able to stay in contact with the tooth surface for several
hours. It may be applied to the enamel, dentine or cementum of the tooth and can
be used to help prevent decay, remineralise the tooth surface and to treat dentine
Fluoride varnish is composed of a high concentration of fluoride as a salt or silane
preparation in a fast drying, alcohol and resin based solution. The concentration,
form of fluoride, and dispensing method may vary depending on the manufacturer.
While most fluoride varnishes contain 5% sodium fluoride at least one brand of fluoride
varnish contains 1% difluorsilane in a polyurethane base.
