Front teeth shifting upward creating an overjet one week after braces are removed, can it be corrected?

I had my braces removed 9 days ago and about 4 days ago I noticed that my front teeth appear to be shifting upward creating an overjet. I know this can't be normal. I called my ortho right away and made an app for 2 days from now. What can he do to correct it? Can it be corrected?
