It has occurred to me a couple of times.
I work in health care and see The Ages of Dentition 😊
No one under 40 has a filling. Everyone from 40-70 has a face like a Cornish tin mine. Everyone older has dentures.
Why?
Please, I'm not looking for any 'Well, I'm 80 with a full set of natural teeth'- I'm generalising 😂
But given that the older folk didn't encounter a grain of sugar on their entire youth (if you were to believe my mother, RIP, b. 1933)... why?
What changed? What factors came into play?
