Tetracycline teeth are caused by taking more tetracycline drugs during tooth development. Tetracycline teeth for many people, for personal confidence is a big blow, so you know how to white tetracycline teeth? What methods can make tetracycline teeth white?
What is tetracycline tooth?
1. It is yellow, bright yellow fluorescence under sunlight, and then gradually turns from yellow to tan or dark gray. This transition is slow and can be promoted by sunlight. The lip of the incisor changes color first.
2. The color of anterior teeth is more obvious than that of posterior teeth, and the color of primary teeth is more obvious than that of permanent teeth, because the enamel of primary teeth is thin and transparent, so it is not easy to cover the color of tetracycline conjugate in dentin.
3. The degree of tooth staining is related to the type, dose and times of administration of tetracycline. It is generally believed that tetracycline, demethyltetracycline and tetracycline hydrochloride cause more obvious coloration than oxytetracycline and chlortetracycline. In permanent teeth, the number of courses of tetracycline is directly proportional to the degree of staining, but the effect of a large dose in a short period of time is greater than that of a long-term equal total dose. 4. Tetracycline causes tooth coloration and enamel hypoplasia, which can only be seen in the period of tooth development. Generally after 6-7 years old, it will not cause eye-catching tooth discoloration. (this article is exclusively compiled by WYH, editor of sihai.com.

How does tetracycline tooth turn white?
1. Bleaching treatment
This is suitable for those with light tooth coloring and no enamel hypoplasia. The treatment can be divided into internal bleaching and external bleaching. Internal bleaching is to put the bleaching agent in the teeth, which has good clinical effect. The disadvantage is to change the pulpless teeth into pulpless teeth. External bleaching is to put the bleaching agent on the tooth surface, the effect is not as good as internal bleaching, but there is no need to damage the tooth.
2. Skin treatment
It can be applied to the teeth with hypoplasia of enamel, but it is not effective for the teeth with severe tetracycline staining. The treatment needs to grind off a small amount of enamel, paste resin, porcelain and other materials on the tooth surface, with high production requirements, good shape, color and moderate price. But after treatment, the veneer is easy to fall off and the teeth cannot bite hard objects. (this article is exclusively compiled by WYH, editor of sihai.com.

3. Crown restoration
It is suitable for all tetracycline teeth, and has good color blocking effect. However, it is necessary to remove more tooth tissues, which may cause pulp inflammation. Some dentists think that to avoid pulpitis, it is possible to change the living pulp teeth into pulpless teeth before crown restoration. At present, porcelain crowns are commonly used in crown restoration. The color of the crowns after restoration is lifelike, but the price is high and the technology is complex.
Tetracycline prevention is very important
Doctors have warned that because tetracycline teeth can only occur when they are given during tooth development, some people are worried about tetracycline discoloration. To prevent tetracycline teeth, pregnant or lactating women, as well as children under the age of 8 should not use tetracycline drugs, after the age of 8, tetracycline does not have much impact. Although the coloring of tetracycline teeth is permanent, it is not incurable, so prevention is very important.
