mini bluetooth light led cold light teeth brighteningScope of applicationYellow teeth, black teeth, smoke stained teeth, tetracycline teeth, betel nut teeth, fluorosis teeth and other pigmented teethparameterVoltage: DC6VLED light: 1Light source: cold light (high intensity blue light between 460-480 nanometer)Light Intensity: 400-600 mcsWavelength: 460-480nmA button battery can work for 48 hours.Product advantages1) Mini home, small and easy to carry2) The unique LED blue light technology can filter other harmful light sources.working principleCold light tooth brightening is under the high-intensity blue light, through the properties of nanoparticles and photolysis, accelerate the activation of hydrogen peroxide, stimulateThe single-line free oxygen atoms are rapidly decomposed, allowing the brightening agent to penetrate the dentinal tubules and the color deposited on the surface and deep layers of the teeth.It produces a redox reaction that brightens the teeth.Instructions1) After applying the gel, turn on the beauty lamp and put it into the mouth for irradiation2) The blue light emitted by the dental lamp will react with the gel to brighten the teeth3) The lighting time of the dental lamp is 10 minutes at a time. If it needs to be irradiated for a long time, it can be extended by turning it on again after the irradiation is completed.
