Whitening and Bleaching


Understand the Difference

First, if you notice the terms “whitening” and “bleaching” seemingly being used interchangeably, it would be appropriate to explain the differences between these two.

Whitening generally refers to removal of stains that are embedded into the layer of proteins known as the pellicle, which naturally covers the surface of the tooth and provides the tooth’s first line of defense from acids that draw minerals from the enamel surface, making it softer. The stains come from foods and drinks containing dark colors, such as coffee, tea, red wine, tobacco, and others. Toothpastes with “whitening” on the label contain an abrasive ingredient that reduces enamel surface stains by mechanical removal of this pellicle. The downside is that this process can lead to abrasion of the enamel and can contribute to tooth sensitivity, especially if there are any exposed root surfaces. The acidity of many over the counter bleaching products like adhesive strips is strong enough to chemically break down this protective layer.
