Why Teeth Whitening

Most of us start out with sparkling white teeth, thanks to their porcelain-like enamel surface. Composed of microscopic crystalline rods, tooth enamel is designed to protect the teeth from the effects of chewing, gnashing, trauma and acid attacks caused by sugar. But over the years enamel is worn down, becoming more transparent and permitting the yellow color of dentin — the tooth’s core material — to show through.
During routine chewing, dentin remains intact while millions of micro-cracks occur in the enamel. It is these cracks, as well as the spaces between the crystalline enamel rods, that gradually fill up with stains and debris. As a result, the teeth eventually develop a dull, lackluster appearance.

How much whiter will my teeth look?
This varies from individual to individual and also the type of whitening system used. Some people respond very well to teeth whitening and have dramatic whitening results whereas others may notice very little difference at all. Your dentist will be able to advise you on the likely results expected with your teeth.
