Question

How are teeth white in colour

Answer 1

The outer layer, known as the enamel, contains a component of calcium, which tends to be white in color. ... Beneath the enamel lies the dentin, or the which is usually yellowish. If the white enamel gets thinner with time, more of the yellow dentin will show through — and teeth look less white overall.

Answer 2

Ok, I will answer it:-

Due to the presence of calcium teeth are white in colour.
