rosequartz It's a long time since there's been a hygienist at my dentist's surgery. The dentist took this over for a while and used to offer a scale and polish, I think this used to be free and then you had to pay for it. Now, you can only have this service by paying for it.
I've always thought that the hygienist service was important, he/she has time to talk to you about gum and mouth health in general, to show you how to brush and floss if you don't know, and will clean and polish your teeth. Gum health is so important for general health and if not paid attention to leads to many more problems later. It seemed to me that the hygienist left the dentist free to do the nuts and bolts of fillings and more.
Looking after your teeth is probably one of those things that gets scant attention from many people, just like not eating properly or taking exercise. I suppose it's then impossible to avoid becoming 'political' because you have to say do you think the state should look after people and their health or do you say 'it's up to them' but of course with the latter, the state picks up the bill at the end of the day anyway, when poor choices, (if you want to call them that and think people have adequate information, time and money to make those choices) lead to poor health outcomes.
I do agree with Eloethan that illness has many causations beyond life choices though and I'd add environmental causes too. The whole of the south east has very bad air pollution levels and so there are many more cases of respiratory illness, especially amongst vulnerable people (the young and elderly) than there would be if we all lived in the mountains. Chance would be a fine thing!
