Dentists in Shenzhen suggest that in this case, patients can extract their teeth in advance, provide enough space, use the physiological movement of teeth to reduce the degree of malocclusion, and then correct tooth crowding after tooth replacement is almost completed.

The advantage of this is that it can shorten the time of tooth crowding correction and make it easier for children. This kind of tooth extraction in advance when changing teeth is called sequential tooth extraction, which has a great improvement effect on the extremely crowded dentition.

However, Dr. Youmu's dentist suggested that we must grasp the timing of sequential tooth extraction. Only when the orthodontist chooses the right time of tooth extraction can it help to improve the occlusion and will not cause adverse effects. In addition, in the case of sequential tooth extraction, it is necessary to fully cooperate with orthodontists during the two or three years from the age of 7 to 8 to101to avoid missing the best opportunity for tooth extraction.

In addition, during the treatment, the orthodontist will put a simple corrective device on the patient according to the situation, and the patient must follow the doctor's advice and get twice the result with half the effort. After sequential tooth extraction, because the arrangement of teeth will be improved a lot, it is necessary to continue to correct. Because most patients with tooth extraction need to install appliances to complete the integrity of occlusion, otherwise there will often be sequelae such as excessive occlusion, incomplete closure of tooth extraction space or non-parallel roots, which is not worth the candle.

Youmu Dentistry reminds that the purpose of sequential tooth extraction is to reduce the degree of tooth crowding and make other teeth arrange smoothly, so surgery can be performed in the mixed dentition period to make the permanent teeth arrange smoothly.
