What are the dangers of cold light teeth whitening?

In fact, the effect of cold light teeth whitening is very good. It only takes half an hour to deeply remove tooth deposits and pigments. However, some people worry that it may cause some harm. This may require considering whether it will cause tooth allergies.

1. Cold light teeth whitening technology transmits high-intensity blue light with a wavelength between 480-520 nanometers through optical fiber, passes through two special optical lenses with more than 30 layers of coating, and then undergoes special optical treatment to isolate all harmful ultraviolet and infrared rays, and quickly produce redox effects on whitening agents mainly composed of hydrogen peroxide and silica with a diameter of 20 nanometers. Through the dental tubules, the pigments attached to the surface and deep layers of the teeth are removed, thus achieving a whitening effect.

2. Cold light whitening will damage the surface of the teeth. It will not only cause scratches on the surface of the teeth, but also make the teeth lose their smoothness. The whitening process will cause damage to the teeth. If you have had porcelain teeth, it may also cause porcelain chipping, discoloration of the restoration, gingivitis, etc.

3. Cold light whitening can also cause tooth allergies, which will make you uncomfortable for a while. The whitening effect usually only lasts about 1 to 2 years. It is not a permanent solution. After the effect is gone, your teeth will be uglier than before the treatment.

4. Cold light teeth whitening uses low-temperature cold light. Since it does not produce thermal effects, it avoids discomfort to the dental nerves. However, since everyone's situation is different, a small number of people may feel sore and swollen teeth. But after cold light teeth whitening, the teeth will return to normal.

5. Cold light whitening is to apply non-toxic and harmless whitening material on the surface of teeth, and then irradiate the entire mouth of teeth at one time. Therefore, cold light whitening of teeth only takes about 30 minutes to remove pigments deposited on the surface and deep layers of the teeth.

6. Cold light whitening is a safe and effective method of whitening teeth. The gums will not be touched during the process, so those seeking beauty do not need to worry about cold light whitening causing damage to the teeth.
