Experts point out that the cold light teeth whitening technology is to transmit high-intensity blue light with a wavelength between 480-520 nanometers through optical fibers, through two special optical mirrors with 30 multi-layer coatings, and then through special optical treatment to isolate all harmful ultraviolet rays and Infrared, a whitening agent with hydrogen peroxide and silica with a diameter of 20 nanometers as the main body, quickly produces redox effects. Through the dental tubules, the pigments attached to the surface and deep layers of the teeth are removed, so as to achieve a whitening effect. The operation time of whitening is not very long, only 30 minutes.
The low temperature cold light completely avoids the stimulation of the tooth nerve during the operation. The main ingredient of whitening agents is hydrogen peroxide. Safe, blue light whitening takes no more than 30 minutes to complete a full oral whitening, and the irradiation time for each tooth does not exceed 1 minute, thus greatly reducing the possibility of overheating or sensitivity of the teeth. High efficiency, the whitening efficiency of blue light whitening is 29.5 times that of using bleaching gel alone. The treatment handle designed according to the ergonomic principle will improve the teeth by 3-4 white degrees after each treatment, and the general whitening effect can be maintained for 3-5 years . It is almost painless and painless during the treatment, so no anesthesia is required.
