Topical fluoride is a preventive agent applied to tooth enamel. It comes in a number of different forms. A dental professional places gels or foams in trays that are held against the teeth for up to four minutes. Fluoride varnish is brushed or "painted" on the enamel.
Varnish is especially useful for young patients and those with special needs who may not tolerate fluoride trays.
Children who benefit the most from fluoride are those at highest risk for decay. Risk factors include a history of previous cavities, a diet high in sugar or carbohydrates, orthodontic appliances, and certain medical conditions such as dry mouth. |
