Tooth whitening

Tooth whitening refers to removing pigments on the surface or interior of the teeth through physical or chemical methods to restore the original color of the teeth; or to make the color of the teeth brighter and whiter by covering them.

Why do teeth change color

Age-enhancing yellow teeth: Young people's teeth are relatively white. After a few years, the color of teeth gradually becomes darker.

Eat colored foods or smoke for a long time.

tooth fluorosis : When I was young, I was caused by the excessive fluorine content in drinking water.

Tetracycline tooth : I have been taking tetracycline antibiotics for a long time, and the metabolites produced by antibiotics in the human body are deposited in the teeth.

Naturally yellow teeth: Just like our skin color, some people have white teeth, while others have yellower.

Tooth nerve necrosis: After tooth nerve necrosis, it will gradually cause the teeth to become darker.

What are the methods of teeth whitening

According to the whitening skill, the teeth whitening methods include teeth cleaning, whitening mouthwash, whitening toothpaste, whitening toothpaste, whitening , cold light whitening , porcelain veneer, crown repair and other methods.

Who can’t do

Minors under the age of 18 can use whitening toothpaste and whitening mouthwash, but whitening patches, tooth bleaching, porcelain veneers, crown restoration, etc. can only be performed after the age of 18. This is because the structure of the teeth will be completely fixed only when it is around 18 years old. Performing these operations too early will damage the internal structure of the teeth. Notes after

:

usually needs to be done twice to achieve the maximum effect. Two times are separated by one week. The first time can achieve 70% whitening effect, and the second time can achieve 90% whitening effect. After two times, no special circumstances are required.

After the porcelain veneer and crown restoration is completed, it is recommended to check once a year to check the oral hygiene and maintenance status and the restoration status.
