It's uncommon here in Norway, unheard of in fact as far as I am concerned. I have a checkup once a year that includes a really thorough cleaning procedure and x-rays. That costs about 120 USD. If I need a filling that will probably add about 100 USD at the most and the two crowns (milled ceramic done on site, on demand) that I have cost about 500 USD each so over the last thirty years I have spent about 6000 USD on dentistry, so an average of 200 USD per year.
