Hello! General doctors will consider these two schemes for the need of treatment, and molars mainly appear in the orthodontic process of porcelain inlay and crown.

The situation of tooth extraction:

1. The teeth are severely crowded and dislocated, and the malocclusion with obvious gaps must be corrected by extraction. Only tooth extraction can achieve the coordination of tooth quantity and bone quantity, the balance of dental arch and perioral muscle tension, so that the orthodontic effect is stable and the deformity is not easy to recur. The main purpose of orthodontic tooth extraction is to relieve crowding and arrange teeth. Patients with double dental arches or patients with sagittal and vertical dental arches also need to extract teeth to obtain gaps, retract the front teeth and move the rear teeth to obtain a stable, balanced and beautiful dental-maxillofacial relationship. It is precisely because of its obvious advantages that tooth extraction has been widely used by orthodontists all over the world, and its orthodontic history has been more than 70 years. Some parents worry that tooth extraction will lead to tooth loss, but it is not necessary. Because of racial evolution, modern people have more teeth than mandibles, and tooth extraction is an active treatment to promote them to move in a coordinated and stable direction.

2, teeth that are not worth keeping or necrotic teeth will be recommended by doctors.
