I don't know if you used a belt when you corrected it, just iron rings and big teeth on your teeth.

Besides, how big is the gap between teeth?

If it is about 1mm, it can be forcibly adducted through the retainer with lip arch, and the effect is limited, but it is also better than now.

In addition, if you use a band ring, you will really plug your teeth in the first few months, and you will get better gradually after applying strength.
