Why do people have gaps in their teeth and what factors contribute to the formation of these spaces between teeth?

Gaps in teeth, also known as diastema, can be caused by various factors. One common reason is the size discrepancy between teeth and jawbone, leading to extra space. Additionally, habits like thumb sucking or tongue thrusting can push teeth apart. Genetics, gum disease, and missing teeth can also contribute to the formation of gaps between teeth.
