What specifically causes the breakdown of teeth? (self.askbiologists)

When you see images of skulls from 100,000 years ago, they have seemingly perfect teeth.

Today, modern humans have terrible dental health. I understand sugar causes a number of issues- the growth of bacteria which decays enamel.

What is the process teeth go through in the modern world to cause this? How quickly after consuming a sugary drink for example does this degradation start to occur?

And as a follow up, how does tooth paste help prevent this?

Do dentures / “fake teeth” suffer from plaque?

[–] ndr 4 points 2 years ago (1 children)

If they're not made of minerals (as is the case with dentures), they cannot demineralize and suffer decay in the same way. Note that plaque, or biofilm in general, can form anywhere.

So, you should practice good oral hygiene, because plaque could cause other infections in your mouth, in particular in your gums.
