What is the primary goal of a fluoride varnish application?

To whiten teeth
To provide a concentrated topical fluoride treatment for caries prevention
To relieve tooth sensitivity
To seal dental restorations

The correct answer is: To provide a concentrated topical fluoride treatment for caries prevention

The primary goal of a fluoride varnish application is to provide a concentrated topical fluoride treatment for caries prevention. Fluoride varnish is a form of topical fluoride that is applied to the teeth to enhance the remineralization of enamel and help in preventing cavities. It works by providing a high concentration of fluoride directly onto the tooth surface, which can effectively inhibit the demineralization process that leads to caries. When fluoride is applied in this form, it adheres to the teeth, allowing for a prolonged contact time, which enhances its effectiveness. This application is particularly beneficial for individuals who may be at higher risk for dental caries, such as children or those with a history of cavities. While fluoride varnish may also offer some benefits in terms of alleviating tooth sensitivity, the primary objective is centered on caries prevention through the application of fluoride. Whitening teeth and sealing dental restorations, while important aspects of dental care, are not the main aims of using fluoride varnish.
