Hello, in the treatment of oral plastic surgery, tooth extraction is very common, and about 66% patients need tooth extraction during the correction process. Because in some cases, such as severely crowded teeth, front teeth protrusion must be corrected by tooth extraction. If not corrected, some cases of protrusion, malocclusion and jaw opening cannot be corrected. There will be gaps after tooth extraction, and doctors will use these gaps to achieve the purpose of correction by moving teeth. After the correction is completed, most of the gaps will be completely closed, and there is generally no need to insert teeth.
