Besides the other explanations of how toothpaste was nice but not needed, another major thing is the relative amount of sugar in our diets today. The average westerner, especially American, gets *way* more sugar in their diet than ever before in history. The more obvious results include spiking obesity rates, but another one is that bad germs in our mouth, teeth, gums, etc. absolutely thrive on sugar, contributing to a higher rate of cavities and infections than there would be without such high intake of sugars.
And then add in the harsh acids and such of pops, sodas, and other drinks on top of the sugar, and your teeth have a hard time ahead of them if you have an unhealthy diet.
