Symptoms of confusion in the neck of the teeth
Although the surface of the tooth is white, it does not fold light, just like the white ash on the wall. This is the phenomenon of incomplete calcification of the teeth. It is called white empty color: the teeth are not hard, easy to wear, and susceptible to caries.
The color of the teeth is dead white: these teeth are caused by insufficient calcium during maternal pregnancy, or serious infectious diseases and chronic diseases in infants and young children.
The color of the teeth is grayish black: such teeth are more common in dental injuries, such as impact, traumatic occlusion, etc., which may lead to endodontic necrosis. The endodontic treatment must be performed as soon as possible, and if necessary, be combined with bleaching for repair.
The color of the teeth is black: the roots of the black teeth are the scale of the teeth, which is caused by the accumulation of tartar and tartar. People who smoke and drink tea also have black deposits of tobacco tea on their teeth. These black matter and tartar and tartar should be removed regularly. At least once a year, the teeth should be cleaned to avoid inflammation and bleeding caused by stimulating the tooth, or cause erosion. If there is any damage, it should be repaired in time.
The color of the teeth is grayish yellow: in the past 20 years, due to the extensive use of tetracycline, oxytetracycline and other drugs, if taken in a long time in early childhood, the teeth of the permanent teeth will turn grayish yellow. This kind of tooth is called tetracycline tooth. It can be used for decolorization and polishing of hydrogen peroxide. It can be used for grinding, refining and grinding. It can be improved. Seriously colored teeth, polished and decolored are still not enough. Repair, or make a photo-curing beauty restoration. Here to remind people to pay attention to the continuous use of tetracycline drugs must be careful, not to take more, and not more than a week, so as not to destroy the teeth. Especially in children with kidney disease, the excretion of tetracyclines is not good, and it is more likely to cause accumulation of body and cause grayish yellow teeth.
