The principle of cold light whitening teeth What are the hazards of cold light whitening

Teeth are relatively hard parts of the human body, but they cannot resist yellowing or disease, so teeth need regular care. Having a mouthful of white teeth will make your smile twice as beautiful.

The principle of cold light whitening is mainly to use the free radicals released by hydrogen peroxide to decompose the colored substances that have been deposited on the teeth for a long time. Hydrogen peroxide is commonly known as bleaching water. And as long as the teeth are deliberately whitened, the existing tooth tissue will be more or less worn, which may cause tooth oxidation and enamel tissue to be damaged, causing the teeth to soften and sink, making you easily uncomfortable when eating cold or hot food.

1. Tooth sensitivity. Some patients may feel uncomfortable after or during the "cold light whitening" process because the teeth are stimulated by the whitening chemicals and cold light, which causes the dentin to lose its protection and cause sensitivity to cold and heat or toothache.

2. Various injuries and diseases. The cold light whitening process will cause a certain degree of damage, such as temporary decalcification immediately after the treatment. In principle, it is not permanent, but if the treatment is too frequent or long-term, cracks will appear on sensitive teeth. It is also possible that teeth will fall out in the later stage due to severe calcification of the teeth.

3. Fluorescent reaction. After cold light whitening, when you enter a dark environment, such as a KTV or a movie theater, your teeth will have a fluorescent effect similar to when we wear clothes containing fluorescent agents, emitting a weird and unnatural fluorescence.

4. Chronic poisoning. A little bit of chemical substances each time may not cause much harm to the body, but if used more often, it will gradually accumulate in the body, increasing harmful substances, which is equivalent to chronic poisoning of the body. In short, cold light whitening agent is a chemical substance. If used frequently, it may even cause oral cancer in the worst case.

5. It is difficult to maintain and is easy to become dependent on. Cold light whitening does not have a permanent effect, and the effect will vary depending on how carefully each person takes care of their teeth after whitening.

If the teeth have other conditions, it is more likely to cause other problems, such as enamel hypoplasia, which can cause tooth cracks or tooth wear; if porcelain teeth are treated at this time, it may also cause porcelain collapse and restoration discoloration. Cold light whitening also has a certain impact on the health of gums, and some people will suffer from diseases such as gingivitis.

The whitening effect usually only lasts about 1 year. Cold light whitening can also damage the surface of the teeth, not only causing scratches on the surface of the teeth, but also causing the teeth to lose their original smoothness. Even after the whitening effect is no longer effective, the teeth will be uglier than before.
