Reading into this, it seems like there's actually a lot going on right now when it comes to sorting out our decaying (ha) dentistry services.
Good.
If this gets well and truly sorted, this will be a visible, tangible thing people can point to and say they've done well there.
People can't really conceptualise the less visible things like "wages have gone up by 2% more than inflation this year", "inflation has dropped by 0.3%", "infrastructure investment has been raised by X%!"
We're bad at understanding numbers like that and visualising what impact they will make on our lives over a longer period of time.
The difference between "I've not been able to get a dentist appointment for 4 years" and "I can trivially have one booked every 6 months" is something that everyone will notice and appreciate.
