At birth, the skull and face grow at wildly different rates — the head that looks "too big" for the face is not a proportion error, it is the plan. This chapter follows the skull and jaws from that first mismatch through to the adult proportions orthodontics is built to understand.

An archwire doesn't move a tooth directly — it moves the periodontal ligament, and the ligament tells the bone what to do. This chapter follows that chain: from the fibrous tissue holding a tooth in its socket, to the pressure and tension it feels under load, to the cells and molecular signal that turn "squeezed" into "resorbed" and "stretched" into "built."

Long before a tooth appears in the mouth, it is already moving. This chapter follows that hidden journey: from a crown sitting quietly in its bony crypt, to a root that elongates and drags it upward, to the same resorb-here/build-there bone machinery from the last chapter now working vertically instead of sideways, to the preformed path it follows through bone, and to what happens when any link in that chain breaks.

Every mechanism in the last two chapters can fail in a specific, recognizable way. A blocked path stalls a tooth in impaction. The follicle that clears bone can instead trap fluid and become a cyst. A ligament that never regenerates after injury lets bone fuse directly onto root, freezing a tooth in place. And a primary tooth's own exfoliation depends on the same resorption machinery being aimed at its root instead of bone. This chapter follows each failure back to the normal process it broke.
