In brief: Root-b-gone

Resorption of the roots of deciduous teeth triggered in part by the advancing permanent teeth is why they get loose and fall out easily.

In brief: Chicken/egg

Which came first, the baby tooth dissolving away to make room for the permanent tooth to erupt, or the permanent tooth erupting making the baby tooth root dissolve away.
Probably a little of both. The i'm portent thing is timing. On the sides baby teeth are wider than permanent teeth. If a baby tooth is not lost at the right time, it can adversely affect occlusion. Need for orthodontist?
