Straightening the visible part of the tooth is only half the process; the root, anchored in the jawbone, acts as the essential foundation for stability. If the root is left at an improper angle, known as incorrect torque, the tooth remains mechanically unstable regardless of how straight it appears. Mastering this complex biomechanical force system is a hallmark of specialist orthodontic training. Proper root control is what distinguishes comprehensive specialist care from simplified, cosmetic tooth-straightening; it is essential for patients who want a result that is not only visually pleasing but biologically stable, preventing teeth from shifting back post-treatment.
