Strangely enough, medieval Brits like Richard III had perfect teeth, with no cavities.
The british bad teeth dates from the industrial era when their diets wee6bad, they had a lot of sugar from the Caribbean and poor hygiene
Yeah, I’ve seen pictures of british nobility teeth from the 1400 to the 1500’s that illustrate your point.
In the 1400’s the teeth were perfect.
In the 1500’s the teeth were rotted to the root.
The difference? The introduction of sugar. Sugar was popular with the nobility.
What’s happened over 400 years has been that sugar has become available to everyone else. With the same effect—but now its worse because so much sugar is available.
Scientists have recently found that huge amount of sugar in the diet is responsible for most of the big western diseases.
