My original response were specifically about references. But sorry if it sounded more aggressive than it was. I mistook you for the original person I replied to, which made me answer more direct than maybe was necessary. Also, it was my bad for not linking the actual reference for WHOs adult data. I'll link it here instead [1]. That said, on second look it is from 2000, so it is much older than the one on children. Maybe not as reliable. I remain am quite sceptical to the claim that there is an actual difference between in oral health between EU and US though. And my original response were to someone saying preventive care is completely non-existent in EU, which is simply demonstrably wrong.
Sorry that it took me so long to respond. I was wrong to over generalize to the EU. My personal experience is with countries around the Mediterranean and I maintain that while it may be available it’s not taken advantage of the way it is in the US.
