How does polishing affect the uptake of professionally applied fluoride?

Professionally applied fluoride is essential for remineralizing teeth and preventing decay, and several factors can influence its effectiveness. Polishing teeth prior to fluoride application generally does not impact the uptake of fluoride. In fact, the purpose of polishing is to remove stains and plaque from the enamel, resulting in a smoother surface. While a clean and smooth surface can enhance the aesthetic appeal of the teeth, studies show that the polishing process does not significantly alter the degree of fluoride uptake in the enamel. This means that whether a tooth has been polished or not, the ability of fluoride to be absorbed by the tooth remains unchanged.

Understanding this concept is important for dental professionals because it underscores that while polishing has its benefits for cosmetic reasons and in removing debris, it is not a critical step in enhancing fluoride absorption.
