Quick question about the social health programs detailed in Sicko

[Squatch]

In those countries offering social health programs that were highlighted in Sicko, do those programs offer (and pay for) cutting-edge treatment or do they only offer the minimum acceptable treatment?

Say I have a bad cavity and am treated by an English dentist. Will I be given a color-matched porcelain filling or the standard silver amalgam filling?

I am tired of wearing glasses, will an optometrist recommend PKR or lasik or even contact lenses? Will the state-sponsored healthcare pay for those more expensive treatments?

Say I have a strange form of some disease that has been heretofore incurable. A new "wonder drug" that has not gained widespread acceptance but has shown promise is released to treat my ailment. Will the state healthcare pay for or even consider that drug?
