Can Teeth Whitening Led Light Really Whiten Teeth? The answer is yes. It uses peroxides, such as hydrogen peroxide, carbamide peroxide, etc., to whiten teeth and achieve whitening effect. In principle, it can be called a home-use version of cold light whitening.
Conventional cold light whitening, high-intensity blue light with a wavelength of 480-520 nm is used to irradiate the teeth coated with bleaching agent, and the blue light is used to accelerate the reaction between the oxides in the bleaching agent and the pigment on the tooth surface to achieve a whitening effect. The concentration of peroxide used is about 30% or more, which is highly irritating and requires trained professionals to operate.
However, in order to take into account the effectiveness and safety, compared with the conventional cold light whitening, the concentration of peroxide and the intensity of blue light are significantly reduced in the home dental device.
Moreover, it is economical, simple to operate, and is not limited by time and location. When you play your phone, wear a mask, read a book, work, or recline on the sofa, you can simultaneously whiten your teeth.
