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.
Dogs have two sets of teeth: puppy and adult. They start loosing their puppy teeth usually at around 3 months and finish losing them by five or six months, at which time they have all been replaced by adult teeth.
hell most kids brush
the sun sets at the same time
No, they are disjoint sets.
about 80. they lose them and grow them like crazy tho.
walk around the house and brush your teeth at the same time
teeth cant grow more than two at the same time
Either a round or a duet.
They had teeth that were constantly replacing used teeth. They had about 1,000 teeth. But not all at the same time! They probably could replace a tooth about 6 times.
The sun sets in the west, not in the east. It rises in the east and sets in the west due to the Earth's rotation.
The sun sets at about the same time as any other location on the same latitude. The time depends upon the specific time of year.
The New Moon rises and sets at roughly the same time as the sun.
