Losing Baby Teeth

Humans have probably evolved the mechanism of tooth replacement to accommodate having dramatically different jaw sizes over the course of our lives.

When we were young, the bones that anchor our lower and upper teeth are small compared with the size they will be when we were adults. Because of having bigger jaws, our body develops more teeth that are bigger.

As babies, our teeth push its way through the gums after a series of development. Teething usually happens without complications.

Children almost always have 20 primary teeth, with rare cases of extra teeth that may appear. All of these baby teeth will be lost eventually as the adult teeth begin to push out the baby teeth that are in the way.

The baby central incisors (the front teeth) would usually be lost at about 6 years of age, the lateral incisors would be pushed out at about 6 to 7 years, while the canines, first molars, and second molars would be lost between 10 and 12 years of age.

Our teeth may undergo development while inside the gums, but once it comes out it stays the same size.

If your child kept our baby teeth through the dramatic changes that happen as we grow older, we wouldn’t be quite as good at chewing food, and we would look kind of funny.

And once we have all of our adult teeth, we have to take good care of it. We don’t grow new teeth after that, and losing our adult teeth would require replacements with the help of your dentist.
