Why do we lose our baby teeth?

Question

Why can't we just grow our permanent teeth when we are a baby and not have to worry about losing our baby teeth?

Answer 1

because its not fair for the other teeth underneath the babyoness

Answer 2

Because we're not babies anymore...Duh.

Answer 3

As we grow so does our jaw/mouth, if we were to grow permanent teeth from birth they would be far to large for our mouth and make all of our teeth super crooked, basically baby teeth are much smaller then your adult teeth.

Answer 4

Because they would be too big for or mouths and we wouldn't be able to eat or talk properly.

Can you imagine a 2 year old with adult teeth? It would be ridiculous. So, we grow smaller ones that can suffice our childhood years. Then they break free and stronger, bigger, sturdier teeth take there place.
