The rubber band can adjust the center line, which can prevent the teeth from dislocation after being pulled to the predetermined position and affect the overall effect. Adjusting the midline can make the teeth look more beautiful.

Rubber bands can also improve the malocclusion of teeth and slowly adjust the dislocation to a neat place.

In addition, the rubber band can make the bite closer, make the upper and lower teeth stick together tightly, maximize the occlusal contact area, and help maximize the chewing efficiency.
