Dental is tricky in many countries. It's delicate, easy to go wrong and very often painful. In Poland I used to do simple things like fillings using public insurance and I've heard many times that I'm crazy and for sure they will fuck it up. I think it's simply because it's it expensive and will go wrong people will think it was inevitable. But if it's free and goes wrong people will say it's because it was free. So in my experience even if public insurance covers dental people tend to avoid it.
