5 Our Changing Teeth-2 By the time we reach the age of seven, our baby teeth begin to fall out. First, the front middle teeth fall out. Then the teeth on the side, and finally the teeth at the back of our mouth. Don't worry though. As our baby teeth fall out, new teeth grow to take their place By our late teens, we will have all 32 of our adult teeth. But unlike our baby teeth, the adult teeth will be with us for the rest of our lives. That's why it's important to take care of these teeth. They are the last ones we will ever get.
My front teeth fell out last week.
