How long before an impacted tooth ligation chain pulls the teeth into place?

That depends: On how deeply impacted the tooth is and what it's position is (horizontal, angled or vertical). Age also plays a role. The older one is, the longer it takes to come in.

Give or take 11 mo.: There are many variables to consider here. The severity of the problem affects the length of treatment. Length of treatment can range from 6 to 27 months, but an average time frame would be 11 months.

UNDETERMINED: This is a very subjective question depending on multiple factors.

Chain: The chain is passive. It simply gives the orthodontist a handle to which a force system can be attached. Depending on tooth’s position, angulation, orientation, overlying tissues, can take 3months to a year to bring into functional occlusion. Best person to answer your question is the Dentist or specialist Orthodontist that is treating you.
