Why do some people’s teeth are straighter than others?
Quick Answer
Tooth alignment depends on jaw size, tooth size, genetics, childhood habits, and how the teeth erupt. If the jaw is too small for all the teeth, crowding and misalignment are more likely.
The Full Story
Teeth grow in through a combination of genetics and space available in the jaws. If the upper or lower jaw is relatively small, the teeth may crowd, overlap, or rotate as they erupt. Childhood habits such as thumb-sucking, tongue thrusting, or prolonged pacifier use can also influence alignment. Injuries, early tooth loss, and differences in growth timing can add to the variation. Orthodontic treatment works by gradually moving teeth into healthier positions, but natural alignment differences are very common.
