Are human teeth born yellow? Why this color?

The dentin of a healthy person is yellowish, so the teeth are naturally a little yellow, which is the structure of a normal body. When we watch toothpaste advertisements, we will find that the teeth of those models are unusually white! On the other hand, our teeth feel yellow. Why are other people's teeth so white, and we are yellow since childhood? In fact, people's teeth are yellow, after all, dentin is yellow, and most people with white teeth have poor calcification or whitening effect in the later stage.

Dentin, like our skin, is yellow, so our teeth are yellow from birth.

It is said that healthy teeth are yellow, but this statement is true. The healthiest teeth of human beings are actually a little yellow rather than white. People's dentin is yellowish, not white. Those people with white teeth we see are basically white! Not to mention the spokesperson on TV, no matter how healthy human teeth are, it is impossible to appear that exaggerated white. Although yellow teeth don't look good, cleaning is enough. There is no need to exaggerate whitening. After all, the teeth themselves are not as bright as white paper.

Second, the teeth are too white, either they are not white when they are calcified, or they have turned white.

Why do some people have white teeth? There are two possibilities, one is that dentin is not directly covered when teeth are calcified, and the other is artificial whitening that we often see. Artificial whitening is to coat the teeth with a protective layer to make them look particularly white; Although it looks refreshing, there will be a strange feeling, and even I think this person will be a little exaggerated. Just wash your teeth normally. Why do you have to make your teeth so white? Therefore, the color of teeth is naturally enough, not necessarily white.

Human dentin is yellowish, so teeth are naturally yellowish, which is a healthy tooth color.
