Why do some people never lose their baby teeth?

Answer 1

Because the tooth nerve is made up of three major parts that cause the baby tooth to be pushed out and a new one to come in. sometimes not all of the teeth get reached therefore the person with this problem probably will never even get wisdom teeth. it is rare yet it happens.

The same thing happens with hair in some people. it grows only to a certain length and may break off at any given point and will not ever grow any longer than it's greatest length. that's because the hair goes through the growing phase, the resting phase, the done growing stage.

on one person the fullgrown hair is 9 feet 7 inches, on another person, may it only be 8 inches total.

everyone is different therefore it makes sense.

Answer 2

The basic method nature provides to replace the baby teeth is that the roots start to decay when the adult tooth starts to grow underside the baby tooth, and when the roots are gone, the baby tooth will pretty much fall out. But if for some reason you're not getting that adult tooth, the baby tooth gets to keep its roots, and can stay in there for decades.

Baby teeth aren't as strong as the adult teeth, as they're not meant to last that long, so unless cavitites kill them off, they'll usually crack and fail eventually anyhow.
