I understand that a retention period is necessary even after orthodontic treatment.
They say teeth continue to shake, especially during childbirth.
How long is the approximate duration of maintenance?
Should it be maintained for a lifetime? ㅠㅠ
Orthodontic treatment is not completed in just one session; it requires ongoing care.
That also seems really difficult...
