There are numerous questions and concerns we keep on hearing at our Downtown Vancouver office about teeth whitening
Myth 1: whitening strips enamel permanently from teeth
Myth 2: scrubbing teeth hearder will clean them better
Myth 3: Using a medium or hard toothbrush will clean your teeth and stain away better
How does bleaching works?
Enamel is made out of billions of organized tubes called enamel rods that are aligned like a honeycomb. Underneath the enamel lie the dentinal tubules.
With time, stain infiltrates between the enanel rods and becomes intrinsic stain. The only way to remove that stain without damaging the enamel is through a chemical that reacts with them, like hydrogen peroxide. Hydrogen Peroxide reacts with the stain molecules and cleaves them into smaller & lighter molecules that get washed away. These stain molecules also provide some isolation by plugging access to cold water & air to the sensitive dentin. That’s why your teeth become very sensitive after a teeth whitening session (it actually means that the whitening is doing its job.)
We hope we demystified some of those myths. If you may have any questions, comments or to book a consult, don't hesitate to contact us at: http://www.ariadental.com/contact.php
