When I was young, I started orthodontic treatment, had teeth extracted, and then moved a bit far from the dental clinic, so things just kind of fizzled out and my teeth became a little crooked. But it did not really cause problems in daily life, so I left it alone. Then after turning 30, I got orthodontic treatment again, and I am satisfied with it.
My facial features look a bit more refined(?), so my overall impression looks cleaner, and maybe because my jaw was corrected, I even feel like the shape of my head looks a little different....
In my case, I have a relative who is a dental hygienist, so I got the recommendation and went ahead with orthodontic treatment.
I guess money really does make a difference depending on how much you spend ㅜㅜ
