Tetracycline teeth are caused by tetracycline drugs taken during the development of the teeth, resulting in discoloration or under-mineralization of the enamel and underdevelopment of the teeth. Once you have tetracycline teeth, it depends on the degree of tooth discoloration. If the discoloration is relatively light, it can be left untreated. If the staining is deeper and affects your life and work, then you need to treat the tetracycline teeth with whitening or restoration. For tetracycline teeth, the main problem is the aesthetic impact. Because tetracycline drugs stain the teeth very deeply, usually in a grayish and black color, it is very aesthetically displeasing. If you want to change this problem completely, you will need whitening treatment or restorative treatment. The main whitening treatments are cold light whitening and laser whitening. Generally, the effect of laser whitening is significantly better than cold light whitening. The restoration treatment is mainly the restoration of porcelain veneers and full crowns. If the coloring is light, not particularly deep, you can choose the porcelain veneer restoration. If the staining is very deep and there is enamel loss, then a full crown restoration should be performed. The prevention of tetracycline teeth is very important, and it is important to prohibit the use of drugs that affect the development of the fetus during pregnancy in order to benefit the health of the fetus. Once tetracycline teeth appear, the main thing is the change of color and tooth structure, and the treatment is whitening and restoration.
