How to whiten teeth scientically?

To know how to whiten scientifically, first of all, we need to know: What kind of teeth are white? What is the original color of teeth?

1.Teeth color = Enamel + Dentin

What color should the teeth be? It must not the color of white paper.

In fact, the color of teeth is determined by Enamel and Dentin.

The outermost layer of the tooth is Enamel, which is the hardest part of the human bone. It surrounds the surface of the crown and its color is milky white. The inner layer of enamel is Dentin, which is also very hard tooth tissue, but it is not as hard as Enamel.

  1. What causes the teeth to become yellow?

If the disease is not taken into account, the more mineralized teeth are, the stronger teeth are in theory. But at the same time, it is more likely to show the yellow color of the dentin inside, and looks more yellow.

In addition to the color difference caused by different degrees of congenital teeth calcification, the following are the common causes of yellow teeth:

(1)Long term smoking, drinking tea, coffee and some iron supplements may lead to teeth stain.

(2)Tooth decay and dental calculuslead to yellow teeth. In the development process of tooth decay, the most typical is the discoloration and disintegration of the hard tissue of the teeth; the calculus is attached to the surface of the teeth which is yellow or even black originally and make the teeth look yellow.

(3)Non carious diseases, such as dental fluorosis and tetracycline teeth, can also cause color changes. The former is due to exposure to high fluoride drinking water and chronic fluorosis during tooth development, while the latter is due to exposure to tetracycline antibiotics during tooth development.(These two kinds of diseases are rare now, especially tetracycline teeth)
