Lower teeth orthodontics (consultation/discussion)

When I was young, I had a snaggletooth, and after having my teeth pulled out later, my lower teeth became crooked.

I used to complain about going to the dentist, saying I couldn't see my teeth and that I ran away a lot, but now I really regret it haha.

I'm 고민 whether I should get orthodontic treatment in my 40s or just live as I am. Please provide information or advice about orthodontics.
