Actually, our second set wasn't designed to go quite that long. Now we are living longer - lots longer. But still, it is imbalanced.

I was told that it is because prehistoric man did not live long at all, maybe 20 years or so. So growing up, you would damage your teeth eating rocks and whatever else. Around 9 or 10, it would be time for replacement teeth. Here come the "adult teeth" and then they would be used until you died around 20.
I dont know how accurate that was, but it certainly makes some sort of sense.

Simple really - though it took me a bit of pondering.
Children grow very fast, from no teeth - to some teeth - to a full mouth of baby teeth - to adult teeth. But once our adult teeth have come in our growth slows, and our skull growth has stopped entirely.
So there is no need to keep growing new sets to fit our mouths.
As for wear and tear - we were designed to live about thirty years or so, maybe a bit more... and we're far exceeding our mileage.
At best our design is meant for sixty...
Species that our meant for constant tooth replenishment have that feature, like sharks and some herbivores...
Cool in my opinion...

i never really thought of that. but early humans used to live only to about 20 years. over time people began making medicine and got smarter and figured out ways to make us live a lot longer. that is why it is not evenly spaced out. and i am 11 years old and don't necessarily need candy, but love it. and i have no cavities and that means i take good care of my teeth and can make them last. hope that answers your question!

No because your first set of teeth were being formed on a minimal amount of calcium in your diet (breast milk, or formula). Your second set of teeth were forming after you starting eating foods and taking vitamins.....and did you ever see little kids with black spots on their teeth? It's because their mothers had to take a high dose of antibiotics while they were pregnant!

I think I read somewhere that the reason why you have temporary teeth (as children) and permanent teeth as adults is because of growth of the jaw. We have our first set of teeth to help eat, of course, but as we get older our face changes, jaw grows bigger, etc... With that, we "shed" our temporary teeth and permanent teeth set in. They are larger and fill the mouth better....to prepare us for adulthood.

Because your first 10 years is when you put all kinds of stupid **** in your mouth that your not supposed to. You don't get your real teeth until you can use them responsibly.
