What can be a cause of malocclusion?

Malocclusion can indeed result from oral habits. Certain behaviors, such as thumb sucking, prolonged pacifier use, or tongue thrusting, can significantly impact the alignment of teeth and the overall relationship between the upper and lower jaws. These habits can exert abnormal forces on the teeth and jaws during critical developmental periods, potentially leading to issues such as crowded teeth, gaps, or misaligned bites.

While other factors like genetics, dietary issues, and treatment errors can also influence malocclusion, the selected answer emphasizes a direct connection to behaviors that patients can control and modify, making oral habits a notable cause in developing orthodontic issues. Understanding this allows dental professionals to offer guidance on breaking harmful habits early to prevent malocclusion, thereby promoting healthier oral development.
