Brace-faces: Did your orthodontist delay taking your braces off after he said he already was?

I’m supposed to get my braces off tomorrow but I’m scared that I’ll get in there and he’ll just delay it a month or two (after my whole highschool has made a countdown for me). This is the first time he said he was going to take them off. Did your orthodontist tell you you were going to get yours off and then kept pushing it back?
