Why is tooth extraction necessary in orthodontic treatment?

The main reasons for tooth extraction in orthodontic treatment are as follows: 1. Insufficient oral space: When there are too many teeth or limited space in the mouth, some teeth need to be extracted to create room for properly aligning the remaining teeth. 2. Maintaining balance: In cases where the upper and lower jaws develop unevenly, extracting teeth may be necessary to maintain jaw balance and achieve proper occlusion. 3. Significant pre- and post-treatment differences: For patients with severe crowding or protruding teeth, if no teeth are extracted prior to treatment, the resulting dental appearance after orthodontics may differ greatly, negatively affecting aesthetics.
