It's pretty similar in the UK for private dentistry, x-rays ~£10-30, hygienist/scale/polish ~£50-120, filling ~£70-150, root canal/extraction ~£120-300.
Dentist salaries seem to range between £70-200k depending on experience, specialty, etc.
Very similar prices in Spain too, funny how the UK is generally considered _very_ expensive for dental work, in fact I just paid 40 EUR for an x-ray here yesterday.
Quite happy paying £26.80 / £73.50 for all of that.
It's in a country's interests to help maintain the public's health, and that includes subsidising their dental costs (otherwise, they end up taking up primary care time instead).
For sure, stuff like implants, cosmetic dentistry, braces, crowns etc. still cost a non-trivial amount (though hopefully most are once in a lifetime things).
