I’m not sure if you’re thinking of somewhere else, but Medicare does not cover dentistry - some health services have dentistry but it basically takes care of those who are having poor Health outcomes due to poor dentition (my housemate at Med school was studying dentistry and used to do a couple days out at westmead a week drilling on these people).

IIRC dentistry is only covered in fringe cases for health related reasons i.e. you need this done or you will get very sick or die. Also under some concession schemes. Otherwise, regular check ups, cleaning, fillings, and basic extractions are not covered at all for the general population.
