The Fluoride varnish (with peak plasma levels less than a daily fluoride tablet or brushing with fluoride toothpaste) applied infrequently (two to four times a year at 3-6 moth intervals) is unlikely to contribute to fluorosis in children under age six. (Ekstrand, Koch, Petersson, 1980)
Read MoreThe ADA Council on Scientific Affairs states: “Fluoride varnish applied every six months is effective in preventing caries in the primary and permanent dentition of children and adolescents.” They further state that Fluoride varnish creates less patient discomfort and achieves greater patient acceptance than fluoride gel, especially in preschool-aged children. Two or more applications of […]
Read MoreFluoride varnishes are approved as Class II Medical Devices ( FDA 510 K compliance) for use as a cavity liner and/or tooth desensitizer. Fluoride varnishes is not FDA approved as caries preventive agents. They are used “off-label” for preventing dental caries. FDA approval is not required to use fluoride varnish off-label. (USFDA, 1998, USP DI, […]
Read MoreFluoride varnish works by increasing the concentration of fluoride in the outer surface of teeth, thereby enhancing fluoride uptake during the early stages of demineralization. The varnish hardens on the tooth as soon as it contacts saliva, allowing the high concentration of fluoride to be in contact with tooth enamel for an extended period of […]
Read MoreFor all tooth surfaces, there is a continuous cycle of demineralization and remineralization of tooth enamel. Tooth decay (dental caries) is an infectious, transmissible disease caused by bacteria colonizing on the teeth and producing acid that dissolves enamel, resulting in greater demineralization. All fluorides act to slow demineralization and boost remineralization. Fluorides work in at […]
Read MoreMost Fluoride varnishes are lacquers containing 5% fluoride in a colophony/resin base. Fluoride varnish provides a highly concentrated, temporary dose of fluoride to the tooth surface. The varnish holds the fluoride close to the tooth surface for a longer period of time than other concentrated fluoride products. Unlike low dose fluorides available over the counter […]
