Many people regard bright white teeth as their goal, so they have used various tooth whitening methods and a wide range of tooth whitening products. But are teeth really whiter?
In fact, the true color of healthy teeth is not so white, the strongest teeth are naturally healthy yellowish teeth.
Because the surface of our teeth is covered with a layer of enamel, which is mainly composed of 95% to 97% calcium and phosphorus-containing apatite crystal inorganic matter, which is transparent or translucent. The higher the degree of calcification, the more enamel transparent. The dentin is pale yellow. When the enamel is fully calcified, the dentin will appear, so healthy teeth look pale yellow. Conversely, the lower the degree of calcification of the enamel, the lower the transparency, and it will appear abnormally white or milky white.
Whitening methods such as tooth bleaching, cold light whitening, porcelain teeth, and veneer whitening mentioned in tooth whitening advertisements will cause considerable damage to the teeth themselves.
Teeth bleaching generally follows the principle of chemical bleaching, which is extremely harmful to the enamel on the outer layer of the teeth, and it is easy to make the teeth lose the protection of the outer layer and become extremely sensitive. However, methods such as porcelain teeth wear away the enamel, which may cause problems such as periodontitis and gingival recession.
Therefore, experts say that the natural and coordinated beauty is the tooth color that is suitable for your own skin tone, so not everyone needs tooth whitening.
