Few phrases more reliably set British teeth on edge than this one: “British teeth” — the disobliging characterisation of what our American friends imagine to be the grisly state of our nation’s gnashers. Like “British food”, another snobbish pejorative, it’s not only irritating it’s outdated. British food has been transformed in the past few decades, and so have the teeth with which we chew it.

Perhaps the children of my generation, raised in the 1970s and ’80s, were the last of the dentist dodgers.
