Son having issues at school

My son is six and has SPD, he was doing so well in a smaller class with other kids with behavioral issues. Now he has decided he does not like another student and that he is not going to obey one teacher. He had dental surgery this week and I'm not sure that has helped things, but he has been talking non-stop, not wanting to sit down. He's just been out of sorts. I know he's really upset with another teacher for throwing away his papers (so he says). He got upset with another boy for stepping on his papers. he was doing better in school, I'm just worried about this setback.
