Miniish? Is this orthodontics?

My teeth are crooked.

When I went to the dentist, they talked about mini-sh instead of orthodontic treatment.

I didn't quite understand it correctly and left.

It looks like something is being placed over the tooth.

If you do this, food particles may get stuck more easily in between.

Isn't it difficult to manage?

And this is just for cosmetic effect rather than a fundamental one, right?

Malocclusion, is this something that cannot be treated?
