Many times a smile is the first impression we leave on others, and flawless white teeth are not a charming scenery! But yellow teeth are often neglected. How can we let our teeth be like that discolored white shirt that we wear forever? Cold light teeth whitening technology provides us with a great way to make our teeth whiter. Cold light whitening technology is a high-intensity blue light with wavelength between 480-520 nanometers, conducted through optical fiber, through special optical treatment, to isolate all harmful ultraviolet and infrared rays, the main body of hydrogen peroxide-based pH moderate whitening agent, rapid penetration into the interior of the teeth to remove the surface and deep attached pigments, so as to achieve the whitening effect. It can not only remove the pigmentation on the surface of the teeth, but also enter the deeper layers of the teeth to achieve the effect of decoloration. According to clinical experiments, the use of cold light teeth whitening technology can improve the color of teeth by 5-14 vita shades. The operation process only takes 30-45 minutes. The low-temperature cold light completely avoids the stimulation of the dental nerve during the operation. Hydrogen peroxide, the main component of the whitening agent, has been safely used for decades for tooth decoloration. The tooth structure and enamel are not harmed in any way during the whitening process with hydrophilic medication and complete absence of gum contact. The one-time, non-irritating, side-effect-free whitening effect lasts for more than two years. Therefore, cold light teeth whitening is recognized as the most effective and safest tooth decolorization and whitening technology available.
