Orthodontics
Orthodontic extrusion
Gently easing a tooth or root upward to save it or reshape the gum.
Purpose
Bring tooth outward
Why
Save or restore tooth
Force
Light and slow
Length
Several weeks
Overview
Orthodontic extrusion uses light, steady force to slowly draw a tooth or root further out of the bone. The bone and gum tend to follow the tooth as it moves.
It is often used to bring up a tooth that is broken near the gum line, so there is enough sound tooth to restore. It can also help level the gum before other work.
