When I worked for the Dental Estimates Board which was the final resting place of all those forms you had to fill in at dental surgeries in the 50s, 60s, 70s, 80s and 90s, it was still pretty common for people in some parts of country to have all their teeth removed and replaced by dentures - certainly in Wales, that was the case when I dealt with Welsh dentists - it was like a rite of passage at 21 years old!
This wasn't recently but it was not that long ago; 1976 is when I worked on the Welsh section!
