Do they extract teeth when you have a hair line fracture in your jaw?

It depends on the location and severity of the fracture.

A hairline fracture means the bone is cracked, but if only part of the way through.

In most cases, a hairline fracture in the jaw can be treated without removing any teeth.

Your doctor may recommend immobilizing the joint.

If the crack allows parts of the bone to move independently then surgery is used to insert screws across the damaged site to hold it aligned properly while it heals.
