Do you make sure to get regular dental checkups?

I don't usually have any tooth pain or discomfort, but people around me say it's good to get regular checkups every six months or a year.

I'm actually not in pain, but I'm worried about getting unnecessary overtreatment when I go to the dentist. I'm also concerned that if I keep putting it off, I might end up needing more extensive treatment later.

Are there actually any of you who get regular checkups consistently? I'm curious if it's really helpful and how often people usually visit.
