Children get free treatment.
Finding an NHS dentist can be tricky.
Sweden used to be all about reaping the benefits of both capitalism and socialism, but now our gov't seems to take a perverse joy in making it a "worst of both worlds" type of country.
I would be curious to know what countries today offer what Sweden used to offer. New Zeeland? Canada? Denmark?
So for example removal of tooth would be: dentist 9.60 € /visit + tooth removal 13.80 – 27.50 €
Healthcare, at least where I'm from, doesn't cover preventative dentistry, but it does include anything life threatening which includes the situation from the article. I would sincerely hope the US system would behave similarly.
There are some miscellaneous oddities; for example, if you visit a dentist and have antibiotics prescribed, typically the visit won't be covered (it's a dentist so counts as dental), but the antibiotics will be covered (they're a medical prescription).
And doctor's visits for non-residents are about $40 in Ontario.
