I agrée there is a significant lack of NHS Dentists. Free eye tests stopped for all in 1989, but are still free now for a significant number of people. As far as I know, from friends, hearing tests and aids are still free.
From my experience, to date, the vast majority of care is free. Different from when we lived in France a few years ago where we paid for GP visits, prescriptions and an ambulance.
Perhaps it’s time the UK moved to another model, free for those who can’t afford it, fraught with its own issues.
So, today 4th August 2023 I think you ABU.
