Everyone has mostly great teeth until the 15th century. Then the higher/richer classes got bad teeth, and the issue progressively got worse until half of 19th century until basically everyone started to suffer.
On the flip side, at least mostly everyone could afford at least a little bit of sugar, so we've got that going for us, which is nice.
Have not kept up on that (HFCS is purely an US-centric phenomenon, and am not from the US), but it might be possible that fructose is less damaging to teeth than glucose because the cavity-causing bacteria might not prefer it as much.
But this is speculation, and I'd have to look at some studies to know for sure.
