Could the wire from braces have poked this small hole?

On Aug 3, 2015 I got my braces tightened, I have had them on for about a year, at the dental office the assistant i had was slightly rough. When I went they put a new bottom wire on but the assistant put the wire and the band's on before cutting the wire, so it was poking the back of my cheeks. Today Aug 10, a week later I felt a hole in the back of my mouth near the jaw (kinda were the wire would have poked). It's hard to get a picture of and I had my wisdom teeth removed on June 1, 2015
