Cosmetic dentistry requires the correction of teeth without a medical license, I'm afraid not, but teeth whitening only change the color of the teeth do not move teeth, do not need to apply for a medical license, suggested that the name of the teeth whitening center.
The real teeth white is not easy, what do you use to make all kinds of teeth white? Porcelain you can not do, cold light whitening has limitations, do not use dental paint?
