@USA Gundy and Hithere, despite the old myths, British teeth are statistically better than American teeth these days. We don't generally want the Hollywood smile as it looks unnatural to us, especially as we get older. I believe that British teeth are better than Australian teeth these days too, Nanna8. We have come a very long way from the days of drillem and fillem, which was how many NHS dentists seemed to operate in the fifties, sixties and seventies. I believe school dentists were the worst for this. I would imagine the dark coluring on the Queen's teeth is probably due to het lifelong habit of smoking, which she has successfully given up.
Hithere, you obviously have issues with your own parents/inlaws but many people live in happy families, where questions are only asked out of concern. You seem to delight in being deliberately provocative at times.
