Dilemma - I'm 고민 about whether to get orthodontic treatment.

I'm 고민 whether to undergo orthodontic retreatment.

I have already done it, and I am curious if others in the same situation as me have undergone orthodontic treatment.

It takes a long time and there's the inconvenience of having to go to the dentist regularly. How did everyone handle it?

I'm unsure whether I should do it or not.

Since I am already an adult, I am more worried.
