I don't think it's a very patient centric POV to eliminate relief options and stray away from optimizing them because of off chances like that. I think the high incidence rate of people pushing earwax further in using whatever tool is easily available helps prove that all you're doing is encouraging those with high buildup to get desperate.

I think it's more realistic to recommend, provide and optimize tools for self cleaning than pretend that most people are going to visit the doctor every time their ears are built up (which for some people like me is a weekly occurrence at a minimum).
