To make teeth white quickly, there are two treatment methods as follows: 1.Full-mouth scaling. Full-mouth scaling is mainly applicable to the situation where there are stains and tartar on the surface of teeth. Through full-mouth scaling, sandblasting and polishing, teeth can be made clean and beautiful to achieve the effect of rapid whitening. 2.Cold light whitening. Cold light whitening is mainly applied to the yellowing of dentin and the yellow color of teeth through the enamel, in this case, you can apply drugs on the surface of teeth with cold light to achieve the whitening effect. However, this whitening effect usually disappears naturally after three years and needs to be done again. Both of these methods take very little time to operate and can quickly give patients a set of white teeth.
