How do the teeth whitening products work

 

Everybody likes to have a dazzling bright smile. Some people are naturally blessed with it. They have uniformly arranged ideally shaped white teeth. But the colour of the teeth changes to a slight creamish shade as we grow old. This happens because of regular intake of caffeine, tea, red wine or even smoking. Even people born with that bright smile lose their attraction. So what can they do for bringing back their bright smile?

Well! There are lots of options for whitening teeth. In fact there are so many that one might get confused as to which one to choose. But you need not worry as here I am going to tell you about how these techniques work, based on which you can choose a tooth whitening system.

All the whitening systems use peroxide for bleaching the discoloration and the stains on the teeth. The enamel which is the first layer of the teeth is basically semi translucent. Under this layer there is a second layer which is known as dentine. Since the upper layer is translucent one actually needs to work upon the dentine. For whitening the enamel, this peroxide solution is applied on the enamel. This solution then bleaches the dentine which results in whitening of the teeth.

These methods usually lighten the colour of the teeth up to four to five shades. But the intensity of lightening depends a lot on the discoloration level of the teeth.

There are in office and at home treatments available. The in office may be a little costly and a little more effective as it is done under the supervision of a professional. So, you can choose a method based on your need and budget. Whatever option you choose just check that it is certified by the dental association.
