The gap between my front teeth has started to reappear after braces.

I used to have braces.
It feels like the gap between my front teeth is gradually widening over time.

I didn't really know at first, but
I kept seeing it every time I took a picture.

I thought I had been wearing the maintainer consistently, but
I'm curious why it's going wrong again.

I wonder if I need to readjust even this much.
I would like to know if this can be corrected with a simple procedure.

There are many cases where partial correction alone is sufficient.
I became curious.
