Any dental hygienist on here

Okay so my boyfriend when he was little he fell and his tooth came out when he lived in Dominican Republic. Well there a Dr pushed his tooth back in and used some type of glue to keep it from coming out, and the only issue about that from this day still is that there is a bump inside his nose that puss comes out of and bleeds because of that tooth being pushed back in and super glued! Sometimes when he pushes on it hard on purpose it hurts him. I keep telling him he needs to go to the dentist for it but he will not listen. Is there anyone on here that is a dental hygienist knows why there is a bump in his nose because that tooth and why blood and puss comes out of it? It just builds up.
