Small kids have natural white teeth. The structure of teeth mineral can change in some time. Habits influence teeth color. Tobacco use changes teeth color the way bacterial pigments do. Tooth whitening can reverse the discoloration and restore an amazing smile. At times it is necessary to do tooth whitening for some health reasons as the discoloration causes dental deterioration and therefore the dentist eliminates it for prevention.

It is fast, but applying this method is not absolutely free of risk. In fact the bleaching agent might damage soft tissues due to chemical burns and dentists should thereby supervise all the process very minutely.

The other way to bleach teeth includes placing a strip of material holding a bleaching agent right on the teeth. The dentist generally doesn’t remove the strip in one visit. The patient keeps it for a certain period (a few hours or a few days). Whitening teeth with this method is actually not so convenient as the first one and requires more time. But a lot of dentists recommend the patients to choose this method rather than the fast one. It is due to the fact that this method is carried out with less risk of damaging soft tissues.

But tooth whitening process is not always successful. Some patients may have yellow teeth as they have used some medicines like tetracycline. Tetracycline can cause stains that will not react right away to teeth bleaching. For such cases repeated tooth whitening is necessary to penetrate the layer of dentine and produce the effects.

New procedures involve the light usage to speed the whitening effect. But light activated bleaching is in the infancy stage and has to be studied further. The development of this process will revolutionize teeth bleaching: will make it a safer and faster procedure.
