TEETH WHITENING TREATMENTS & BLEACHING
Teeth whitening is one of the most straightforward ways to give you a whiter and brighter smile. The whitening process can be carried out using a special bleaching gel or by using a special halogen lamp.
Tooth whitening, is a common procedure in general dentistry but especially in the field of cosmetic dentistry. Many people consider white teeth to be an attractive feature of a smile. A child's deciduous teeth are generally whiter than the adult teeth that follow. As a person ages the adult teeth often become darker due to changes in the mineral structure of the tooth, as the enamel becomes less porous. Teeth can also become stained by bacterial pigments, foodstuffs and tobacco.
The procedure to bleach teeth uses oxidizing agents such as hydrogen peroxide or carbamide peroxide to lighten the shade of the tooth. The oxidizing agent penetrates the porosities in the enamel and oxidizes stain deposits; over a period of time, the dentin layer, lying underneath the enamel, is also bleached.
The effects of bleaching can last for several months, but may be shortened by cigarette smoking, and tea and coffee consumption. Tooth whitening only works on natural teeth (ie. not on false teeth).
Tooth whitening can be a highly effective way of lightening the natural colour of your teeth without removing any of the tooth surfaces. Although tooth whitening treatment cannot make a complete colour change, it will lighten the existing shade.
