2, because the tooth surface is covered with a layer of enamel, which is transparent or translucent, and its deep layer is dentin, which is light yellow. The color of teeth is related to the degree of calcification of enamel. The higher the degree of calcification, the more transparent the enamel is, and the true color of deep dentin makes the teeth pale yellow through it. On the contrary, the teeth will appear abnormal white or milky white.
3. Therefore, yellow teeth indicate that your enamel is highly calcified, which is a healthy performance. On the contrary, because the teeth with dysplasia and calcification are mostly white, chalk spots will also appear on the teeth with early caries due to demineralization.
It can be seen that white is not the ideal color for healthy teeth, so people who feel that their teeth are yellow and not white enough should never deliberately beautify and pursue a mouthful of white teeth. Don't unrealistically ask the doctor to use incongruous white dentures for you when inserting teeth and choosing the color of dentures.
