But in China, many people have colored teeth, and yellowing is the most common.
Tooth coloration is mainly divided into endogenous coloration and exogenous coloration.
Exogenous coloring is mainly due to the presence of a variety of bacteria on the tooth surface, which secrete a lot of sticky substances on the tooth surface.
When tea stains, tobacco stains, certain minerals in drinking water and saliva adsorb on these sticky substances, plaque and calculus form, which slowly turn teeth yellow or black.
Endogenous staining is mainly formed during tooth development. For example, tetracycline is deposited in the dentin at a young age, which will make the tooth turn yellow, brown or dark gray, called tetracycline teeth.
Drinking water with too much fluoride, for example, can also lead to dental fluorosis, white chalk, tan patches on the surface of the teeth.

For endogenously pigmented teeth, it is necessary to identify the cause of the disease and then symptomatic treatment.
