So....the adult teeth keep growing untl they break the surface. they're full size then. They get some of their "nutrition" by pushing on the roots of the teeth they will replace and absorbing them. that's why baby teeth have no roots when they come out. If the adult teeth are improperly aligned and not directly above the baby teeth, they can end up smaller than average, and the baby teeth with most likely have to be pulled because they do not lose their roots and stay firmly put.

Also, this is why dentsist like to remove impacted wisdom teeth that are apparently doing no harm except for being a bit sideways -if they start to touch the root of the molar in front of it, they will start to absorb and weaken it.

At least this is my understanding of what I've learned from our various dentists and orthodondists over the past 10 years or so......
