Scaling does not make teeth white. Scaling only restores the original color of the teeth, it mainly removes plaque, tartar and stains attached to the surface of the teeth to make the gums healthier and prevent periodontal diseases. There are many benefits of scaling and it is recommended to have a dental cleaning once a year. If you want whiter teeth, you can use a special cold light whitening treatment to whiten your teeth, but the whitening effect only lasts for about 3-5 years, and your teeth will return to their original color after 3-5 years. Whitening itself can be more or less damaging to the teeth, so if you are a celebrity or a patient with such a requirement at work, you can consider whitening.
