Braces for elementary school students

Do elementary school students often get orthodontic treatment?

The permanent teeth are too large, so there isn't enough space for the teeth to come out, causing them to be crooked...ㅠㅠ

When I was young, my baby teeth were really cute, but I guess it's true that baby teeth should come out sporadically...

I need to see an orthodontist for consultation, but these days, even elementary school students are getting a lot of orthodontic treatment.

It seems like they do orthodontic treatment for adults without extracting teeth, but won't it be very difficult for the child?
