One of the most common procedures in general dentistry is Teeth Whitening, otherwise known as dental bleaching in dental circles. However, what most people are not aware of is the fact this procedure actually falls under the specialized category of cosmetic dentistry. Whatever the category it is placed under, there’s no doubting that, judging by the amount of advertising and publicity that we see on a regular basis, whitening has become mainstream and popular the world over.

Why Do Our Teeth Lose Their Color?

In an ideal world, it would be great if could always have a white smile regardless what we ate or how we took care of our teeth. However, this is simply not the case. The reason why as children we have sparkling white teeth is because our teeth have an enamel surface. This effectively protects our teeth from the effects of chewing and sugar. Nevertheless, over time, this enamel surface is worn down and our dentin (that yellow color) begins to be shown. It’s only a matter of time before we start scrambling to go and see your Cosmetic Dentist.

As the enamel begins to wear down, micro cracks start appearing on our teeth and start to get filled up by stains. What Teeth Whitening does is that it removes these stains and exposes these cracks again. Two things can now occur: they either get re-inforced by saliva or filled up with stains again.

There are a couple of reasons why our teeth get stained:

• As we get older, the more stains our teeth get, and the more harder it becomes to remove them
• If our eating habits include regular doses of red wine, tea and coffee, then our teeth can only get more stained
• Smoking and drug use

Overall, Teeth Whitening is a good procedure to clean our teeth temporarily, not permanently.
