In daily life, many people think that the whiter the teeth, the healthier and more beautiful they are. However, a recent hot search "light yellow is a healthy color recognized by dentists" makes many people "surprised" : The white teeth are not the better ah?

Experts say that healthy teeth are not the whitest, but are natural, shiny and evenly colored.

There's a disease in stomatology called dental fluorosis, which is chalky, the color of your teeth like chalk, but it's not healthy.

The color of the teeth is mainly determined by the structure of the crown.

The outermost layer of the crown is enamel, which is the hardest part of the tooth and the more mineralized it is, the more transparent it is. The inner layer of tooth enamel is light yellow dentin.

Therefore, when the degree of enamel mineralization is high, the yellowish color of dentin will be exposed

When the degree of mineralization is low, the transparency of the tooth enamel is reduced, and the teeth will appear whiter.

Careful parents will notice that when a child changes from baby teeth to permanent teeth, the teeth become less white.

In general, permanent teeth have a higher degree of enamel mineralization than baby teeth, so the yellowish color of the dentin will be more pronounced, resulting in a pearly white or yellowish color of the teeth.

As we age, our teeth naturally turn yellow due to changes in the composition of our enamel, just like our skin color and eyes.

Of course, in real life, in addition to the degree of natural mineralization, there are many external factors that affect the color of teeth, such as smoking, drinking tea, drinking coffee and other habits lead to tooth coloring, making teeth yellow or color spots.

Dental cleaning is mainly to remove dental stones and plaque, and can not make the teeth white, through this way is not advisable.

For those who have special needs for teeth whitening, bleaching can be done, such as applying a high concentration of hydrogen peroxide on the teeth to achieve a more ideal effect.

There are two main types of teeth whitening: office whitening and home whitening.

Office whitening needs to be carried out in the oral office under the guidance of a professional doctor, the effect is significant but the maintenance time is short, usually a few months later the teeth may return to the original color, family whitening can be used as a supplement to the office whitening, prolong the whitening effect.

Before teeth whitening, you should consult your dentist to determine if your teeth are suitable for whitening.

In addition, when there are black patches and abrupt colors on the teeth, it is not necessarily as simple as tooth coloring, and it may also indicate that the teeth are "sick."

For example, the black edge of early caries is very fuzzy, and the boundary of exogenous colored tea stains and so on is clearly different, it is recommended that we go to the stomatology department as soon as possible to seek professional help.

Check your mouth regularly and maintain good hygiene to have healthy and beautiful teeth.
