Nope; this is what we all get, also within the country. We are lucky to have no fluoridated water yet. So those who doesnt take fluoride pills (children) or use fluoridated toothpaste / mouthwater, are pretty well off.
But I am afraid this counts for less than 10 % of the population.

Our best product is the sun dried cod, wild caught. It is a delicacy if one can stand the smell of it.
Even our cod liver oil is ruined these days, with a few exeptions. Tweet
