← All explanationsOrthodontic extrusion

Why is a tooth sometimes moved slightly outwards?

Orthodontic extrusion moves a tooth in a controlled way outwards from its socket towards the biting surface. In selected cases this can make more tooth structure accessible for restoration. A tooth displaced outwards by an accident is an acute injury instead.

For training & practice ↓

Cutaway model of a single-rooted premolar and its supporting tissues; no actual movement is shown. — Reference anatomy; the planned direction would be outward from the socket.

01 / 03

Directed movement

Planned forces change the position. The tooth is not simply pulled out and reinserted.

02 / 03

Access tooth structure

With a deep defect, extrusion can be a possible step before restoration. Enough supporting root must remain.

Tissues and stability

Gums and bone may respond differently. The procedure and subsequent stabilisation depend on the treatment goal.

Often confused

Planned movement or injury?

The same direction term must not make a traumatic displacement seem like planned treatment.

Quick answers

Is extrusion the same as extraction?

No. In extrusion the tooth remains within its supporting tissues; extraction removes it.

Can it save every deeply fractured tooth?

No. The root, fracture pattern and restorability limit the options.

My tooth looks longer after a fall. Should I wait?

No. Seek prompt dental assessment and do not push it back yourself.

For a personal discussion

Editorially suggested question to discuss with Dr Niusha Barahmand Pour:

What conditions would need to be met for extrusion?

For a deep defect, discuss the limits of tooth preservation. After an accident, use an urgent dental contact route.

Learning layer for training & practiceUnderstand terminology and deepen knowledge

Coronal: Towards the crown.
Restorability: Whether a tooth can reasonably be restored.
Stabilisation: Maintaining the position after movement.

Make the distinction

The same direction term must not make a traumatic displacement seem like planned treatment.

Knowledge questionWhat does extrusion mean in a treatment plan?

For learning, not for assessing personal symptoms. Your answer is not stored or sent.

Controlled movement towards the biting surface.
Complete removal of the tooth.
Only whitening the crown.

View answer

Controlled movement towards the biting surface.

Removal is called extraction.
