What is a common consequence of dental crowding when no primary tooth has been lost prematurely?

In cases of dental crowding when no primary tooth has been lost prematurely, overlapping of lower incisors is a common consequence. This occurs because the available space in the dental arch is insufficient to accommodate all the teeth, leading to misalignment. As the permanent incisors erupt, they may not have enough room to emerge properly, resulting in them overlapping each other.

This is a significant issue as it affects not only the aesthetic appearance of the smile but also the function of the bite. Proper spacing is crucial for teeth to align correctly, and when crowding occurs, the dental arch can become distorted, making it difficult for the upper and lower teeth to fit together harmoniously.

While the other choices describe possible dental issues related to misalignment and tooth eruption, they do not specifically stem from dental crowding in the same direct way. The overlapping of lower incisors distinctly illustrates the consequences of having inadequate space in the dental arch due to crowding, making it the correct and most directly related answer.
