Evidently, teeth are placed on gums. Below the gum tissue, there is a ligament called the periodontal ligament that surrounds the roots of teeth and holds the teeth in place. Furthermore, the periodontal ligament connects the teeth to the jaw bones.

In the orthodontic treatment process, the periodontal ligament is pressured in one direction and is tensioned in the opposite direction by orthodontic brackets. As a result of these actions and reactions, a tooth would be loosened in its place and is then fixed on the position to which it tends.
