Dental fluorosis, caused by problems with water quality during childhood development, often affects the teeth of a generation of people in an area. Dental fluorosis is divided into the following types from light to heavy: 1. Simple white plaque: this kind of white plaque is the kind of opaque white, like a white wall, but it does not affect the aesthetics much and usually does not need treatment. 2, mild yellow plaque: this type is based on the previous type of teeth and light yellow plaque, this can generally be removed by bleaching or surface micro-polishing yellow part to achieve the whitening effect. The premise is that the yellow plaque is lighter in color. 3.Moderate yellow plaque: more dense and larger than the previous yellow, the first choice is bleaching, at least the yellow plaque can become lighter, and if you are lucky, you can get rid of it completely. This kind of yellow plaque will have obvious traces after polishing because of the deeper attachment, and need to cooperate with resin filling or porcelain veneer. 4, heavy yellow plaque: basic teeth are yellow, even brown, and the tooth surface is also uneven, there are a variety of small pits and dots, this time bleaching has been less suitable. If the budget is not high, you can resin repair, the advantage is cheap, the disadvantage is that the color, level is not very perfect, durability and sturdiness is slightly worse. To get good results, the best is the porcelain veneer, evenly grinding off the tooth surface of less than a millimeter, and then do a thin all-porcelain flakes glued on, very strong, beautiful, more than three thousand a. 5, particularly serious fluorosis teeth: a lot of enamel loss on the teeth, or a lot of caries, this situation is not even suitable for veneers, because there is not enough enamel can be used for bonding, can only consider doing all-porcelain crowns, grinding off more teeth, can repair a larger range, five or six thousand a.
