If the vertical teeth erupt in a more positive direction and have a normal occlusal relationship, in this case, if extracted, it is likely to lead to gaps in the teeth and affect the overall occlusion, so we can consider keeping the vertical teeth. Other than that, all other teeth need to be extracted. If the teeth are not extracted, it is very likely that the adjacent teeth will be affected by decay. Because of the incomplete eruption of the blocked teeth, they are prone to recurrent inflammation, which may cause infection in the gap between the jaws and the face, and in more serious cases, it may cause osteomyelitis in the jaws, resulting in the need to saw off the bone. Therefore, if the teeth are prone to inflammation, and the eruption is incomplete or incorrectly oriented, it is better to extract them, and there is no harm.
