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 yellowish 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 attractiveness. So what can they do to bring back their bright smile?
Well, there are lots of options for whitening teeth. In fact there are so many that one might get confused when it’s time to choose. No need to worry, because there are a number of techniques that work, and you can choose the best tooth whitening system that will fit your teeth’s needs.
Most of the teeth whitening systems use peroxide for bleaching and treating the discoloration and stains on your 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 its surface. 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-clinic and at-home treatments available. The in-clinic 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 make sure that it is certified by the dental association.
