Thumb sucking can significantly impact orthodontic health, primarily by potentially leading to misalignment of teeth and alterations in jaw growth. When a child frequently sucks their thumb, the continuous pressure exerted on the teeth and the surrounding oral structures can cause the teeth to shift out of their intended alignment. Over time, this habit may also affect the development of the jaw, leading to issues such as an open bite or a protruding upper front teeth position, as the normal eruption pattern of the teeth is disrupted.

It's important to realize that the natural growth patterns of the jaw can be influenced by external habits like thumb sucking. This may result in a mismatch between how the upper and lower jaws align, which can compromise the overall occlusion and potentially lead to more complicated orthodontic issues.

In contrast, other options suggest outcomes that do not accurately reflect the consequences associated with thumb sucking. For instance, it does not improve alignment of teeth, nor does it eliminate the need for braces; instead, treatment may become more complex based on the extent of any misalignment. Furthermore, saying that thumb sucking has no effect on orthodontic health overlooks the well-documented potential issues it can create.
