Why should polishing not be performed before fluoride application?

Polishing should not be performed before fluoride application because it is not necessary for fluoride absorption. The primary purpose of fluoride treatment is to strengthen the enamel and provide protection against cavities. Fluoride works effectively when it is applied directly to the tooth surface, allowing it to penetrate and be absorbed into the enamel.

Engaging in polishing prior to fluoride application can remove the outermost layer of plaque and debris, but it does not enhance the fluoride's ability to be absorbed into the tooth structure. In fact, polishing could potentially interfere with the retention of fluoride on the enamel surface for a longer period.

This understanding is important for maintaining effective preventive dental practices, as applying fluoride to a clean enamel surface without prior polishing can optimize its benefits and contribute significantly to oral health.
