Where I am in the US, dentist schedules 6 months out, doctor likes you to schedule annual exams a year out and non urgent a couple of weeks at a minimum but there are some urgent care appointments available each day (or most days). Dermatologist and GYN a couple months wait for routine care. But there are lots of independent urgent care standalone clinics, including for orthopedic stuff, so for broken bones I did not have to go to the emergency room and incur that cost.
It’s uneven I would say. Definitely not worth what we are paying in taxes, insurance premiums and payments to providers, though.
