Are the effects of cold light teeth whitening permanent?

Cold light whitening teeth, based on the physical principle of tooth staining, uses a high-intensity cold laser with a wavelength between 480-520 nanometers to shine on the teeth coated with whitening agent. The whitening agent undergoes oxidation and passes through the dental tubules to remove the pigment on the teeth, thereby whitening the teeth.

Advantages of home teeth whitening

Compared with the cold light whitening instrument in the hospital, the home teeth whitening is relatively mild, with a significant reduction in the concentration of peroxide and the intensity of blue light. The advantage is that it is economical, easy to operate, and not limited by time and region. The disadvantage is that it takes multiple uses to have a more obvious whitening effect, and when the color reaches the desired level, it also needs to be consolidated from time to time to maintain it. Teeth whitening is not permanent.

It can be seen that objectively speaking, although the concentration of peroxide and the intensity of blue light of home-use teeth whitening instruments have been significantly reduced, they are still effective for teeth whitening. But the question is, why are there mixed reviews on the market for home-use teeth whitening instruments? Some people also think that home-use teeth whitening instruments are IQ taxes? In fact, the problem does not lie with the instrument itself, but with the market.

market trend of teeth whitening

In recent years, the popularity of teeth whitening devices has also made many businesses eye this business. Just flipping through the grass-growing platform, you can see various recommendations for teeth whitening devices. But many of these teeth whitening devices are actually three-no products, without national certification, and lack supervision, so safety and effectiveness are difficult to guarantee. In particular, many of the links posted by WeChat merchants do not see the medical devices or drugs and approval documents of the product.

After all, teeth whitening devices require the use of whitening agents. Whitening agents themselves contain bleaching ingredients such as hydrogen peroxide, sodium perborate and hydrochloric acid. If they are non-medical agents, they are easy to damage tooth enamel, causing tooth sensitivity, oral soft tissue or gum irritation, and even tooth demineralization. How much damage to the body is immeasurable.

On the other hand, in fact, teeth whitening devices are not suitable for everyone. Before teeth whitening, you need to do a comprehensive dental examination to see the internal situation of the teeth and whether they are suitable for teeth whitening. If there is really a problem with the teeth, for example, patients with severe periodontal disease, you need to repair the teeth first, deal with the tooth problems, and then whiten them. Otherwise, it will lead to worsening of dental problems.

Instruments that act on the body must not be done as long as they are done. All applications must be based on safety. Only safety first can be effective.
