How does polishing affect the uptake of professionally applied fluoride?

Polishing teeth prior to fluoride application has been shown to have no significant effect on the uptake of fluoride. The process of polishing removes surface debris and plaque, which could theoretically expose the enamel to fluoride more directly. However, studies suggest that the polishing process does not enhance or hinder the fluoride's ability to be absorbed into the tooth structure.

The absorption of fluoride primarily occurs through the enamel and dentin after the fluoride application, regardless of whether the teeth have been polished beforehand. This is important in understanding dental hygiene practices; the efficacy of fluoride treatments remains consistent, allowing dental professionals to focus on thorough fluoride application without being overly concerned about the polishing process impacting the treatment's effectiveness.
