When I first started wearing braces, I had a deep overbite. I've been wearing them for 1 year & 7 months, and the past few months my bite has been improving without the need for rubber bands.
However, two days ago, when powerchains were put across all of upper teeth, my bite changed again.

Now, only my front teeth touch fully when I bite down. All my other teeth barely touch and have big gaps between them.
It looks a little like this picture, but the gaps are MUCH larger in my bite.

I'm very worried....how are they going to fix this?
Should I call in for an emergency appointment?
Will I need rubberbands to fix this overcorrection?
