[Orthodontics] It's already been 5 years since I finished orthodontics

It's been 5 years since I started correcting in my late 20s. I had an unextracted tooth and a slightly open bite. It didn't take 2 years and I was satisfied, but it seems to have relapsed a little because I didn't wear a maintenance device well. But it's much better than before correction. Even if the maintenance device is annoying for ordinary people who have just completed their correction or have just completed it, I hope they wear it well for a year.
