Once you complete the phase with braces and aligners successfully, the next thing your dentist will suggest is getting a spring Hawley retainer. After the removal of braces or aligners, your teeth and gums are still in a soft condition. There is a slight chance of them getting misaligned again. But retainers restrict your teeth and gums from moving from their fixed place. Therefore, retainers are necessary.
