It is a bit weird to pick Sweden for that example because you do have to pay for dental care yourself too. There are some subsidies of course, but it isn’t abnormal to pay the equivalent of 100 EUR for a visit, even if its just to clean teeth from toothstone.
I got scammed a few times when the hygienist or dentist just told me they really need to show me how to properly brush and then I get charged another 50 EUR just for that. Without them telling me beforehand that this will cost extra.
Unless you are under 18 (or under 25?), then it is free at least. But really it should be free for all under general healthcare.
Source: me, I live here and its the example I used in my comment above.
