The teeth thing is really stupid because we have universal single-payer dental care.
I guess it's because we don't go in for bleaching? Teeth are naturally off-white and slightly crooked. Personally the filed-down, completely straight, dazzling white American style looks alien.
The Americans who can't afford dentists likely have worse teeth than our people on similar incomes.

I love watching American films from the wartime, because your accents were amazingly British until the second half of last century. It's only recently in history that even the elite of your society speak with "American" accents.
