If there are retained milk teeth, the permanent teeth may become misaligned. If the milk teeth are extracted earlier and there is enough space in the jawbone, the permanent teeth can usually return to their position automatically. If the milk teeth are extracted later and there is not enough space in the jawbone, the permanent teeth will not be able to return to their position automatically.
1. If the milk teeth are extracted earlier, the tilting angle of the permanent teeth is smaller, and there is enough space in the jawbone, usually the misaligned erupted permanent teeth will be reset automatically.
2. If the milk teeth are extracted late, the permanent teeth have already formed in the lingual apical foramen and the eruption potential is relatively small, which will result in the permanent teeth not being able to return to their position automatically. Or the jawbone is not positioned sufficiently, which can also cause the permanent teeth to be misaligned and unable to return to their normal position.
In case of misalignment of permanent teeth due to retained milk teeth, timely consultation should be made and extraction should be carried out promptly under the guidance of a professional physician to prevent the permanent teeth from being severely unable to return to their normal position automatically.
