I kept thinking about it until I was 32, and I finally got orthodontic treatment at the late age of 32, finishing at 34. In the end, my life feels divided into before and after orthodontic treatment. My appearance changed a lot and my impression improved too. I went to a specialist orthodontic clinic in Seomyeon, Beauty Smile Barun-i. For reference, it was a bit expensive. But they were very kind and very good.
If you have even a little bit of a concern about protrusion and have ever thought about orthodontic treatment, do it without hesitation. If extraction is necessary, do it. If you won't do that, don't do it at all. You need it to see the effect. I saw a lot of posts about side effects of orthodontic treatment, but I think the value of living with upgraded looks and impression for the next several decades is greater.
There will probably be many people worrying about it at a late age, but I don't think it's too late at all. Please do it. *The real effect shows up 3 months after orthodontic treatment ends. For 3 months after the braces come off, things settle into place naturally and get better.
