In Canada the public health cover doesn’t cover dental so you’ll have little luck in that category. You might get a free cleaning and scan but little else. It’s like one of the few things they’ve been dragging their feet on still.
A lot of people live on Advil until the tooth falls out on its own. Or if they can afford the cheap option: have it pulled.
You still need to get private coverage for anything more.
There’s a recent federal Canadian dental health care plan that expands the options for people who make under 90k a year or something along those lines.
