1. A child's jaw is smaller and requires smaller teeth. That's why when we are born and we start growing out teeth, those teeth are temporary and fall out later on.
2. People needed their teeth to live. Having two sets of teeth (and periodically growing more teeth, like molars and wisdom teeth) meant that even if the front teeth rotted away, the person would still be able to eat. Dentistry hasn't been around anywhere near as long as humans have.

∙ 13y agoIn many cases, it is because some are prey and some are predators. It is generally the carnivores that have sharp teeth as they need them to tear apart meat. Herbivores, on the other hand, have "duller" teeth as all they only eat plants and therefore sharp teeth would be unnecessary.
Of course, there are always exceptions, and having sharp teeth is not necessarily restricted to carnivores. The panda, which is completely herbivorous, has particularly sharp teeth, but it also has flat molars for grinding the bamboo shoots it eats.
