Money well spent from my pension pot.
Maybe so, Bucks, but not everyone can draw money from a pension pot, and toothache is the Devil's own work. In a rich country like the UK nobody should have to suffer toothache, and I would argue that nobody should have to have missing front teeth unless for some reason they choose to do so.
As I said upthread, I am in the middle of a course of treatment that is costing £3k. I can find the money, but resent having to do so when there is such an unbalanced system which would offer the same treatment for a tenth of that if I were lucky enough to be able to get an NHS dentist. I am also very aware that a lot of people can't find that sort of money and would have no choice but to have the teeth extracted. This would still cost a pretty penny - my extraction is going to cost £200 as it is 'complex', which a lot of people couldn't afford.
It may be 'money well spent', but not everyone can afford to spend it, so saying that is equivalent to telling someone about the benefits of First Class travel when they have to think twice about going Economy.
