Coronal Polishing and Fluoride Coronal Polishing and Fluoride ApplicationApplication

Historically teeth were polished to remove all Historically teeth were polished to remove all soft deposits and stains before the application soft deposits and stains before the application of fluoride because it was believed that there of fluoride because it was believed that there would be greater uptake of the fluoride into would be greater uptake of the fluoride into the enamel. the enamel.

As scientific knowledge has evolved, it has As scientific knowledge has evolved, it has been shown that polishing does not improve been shown that polishing does not improve the uptake of professionally applied fluoride. the uptake of professionally applied fluoride.

Therefore polishing is no longer necessary Therefore polishing is no longer necessary before fluoride application. before fluoride application.
