Question) Is it okay to start orthodontic treatment now that I am an adult? I am curious about the cost and duration.

My teeth weren't a big issue when I was young, but they became uneven starting when my wisdom teeth came in. Now that I am an adult, my teeth have already fully settled. Because of this, I am wondering if starting braces now would be worthwhile. I have heard that braces are most effective when done during childhood, so I am worried that it might be too late. However, I have been stressed about the shape of my teeth for a long time, and I feel that getting braces would help me regain my confidence, so I am hesitant. Also, I have a question. Cost and duration of adult correction I have heard from those around me that it takes at least two years and costs anywhere from several million to nearly ten million won, but I don't really have a sense of how much it actually costs. I would like to hear your experiences or advice on whether starting orthodontic treatment as an adult is sufficiently effective, and what I should expect regarding the cost and duration.
