(Concern) Misalignment after orthodontic treatment

I started orthodontics in my early twenties.

And then I finished everything, received the correction treatment, and had a prosthetic placed inside my tooth.

However, I didn't go for dental check-ups often, and as one or two inner braces fell off, my teeth shifted, so I had to get a second round of orthodontic treatmentㅠ

But I can feel that the correction is changing slightly and subtly... Should I just be satisfied with this level and leave it as it is?

The orthodontic treatment is finished, but I get anxious every time I notice subtle changesㅠㅠ

But others don't know, haha. It's a change only I can feel~~
