← All explanationsOcclusal trauma

How can excessive loading affect tooth support?

Occlusal trauma means injury to the supporting tissues from forces exceeding their capacity. An unusual tooth contact alone does not establish that injury.

For training & practice ↓

Cutaway of a single-rooted lower premolar with bone and a ligament space widened for explanation; no overload injury is depicted. — Ligament enlarged · no injury depicted

01 / 03

Force meets tissue

Fine fibres anchor teeth in bone. Load capacity also depends on the remaining support.

02 / 03

Assess findings together

Mobility and discomfort have several causes. Contacts and periodontal support need joint assessment.

03 / 03

Separate inflammation

Mechanical overload differs from biofilm-associated periodontitis. Bite adjustment cannot replace indicated periodontal care.

Often confused

Contact versus injury

Occlusion describes contacts; trauma describes tissue damage.

Quick answers

Does a high contact prove trauma?

No. A contact finding and tissue injury are different.

Does overload automatically cause periodontitis?

No. Excessive forces and inflammatory disease are distinct issues.

Must a mobile tooth be removed?

Not automatically. Its cause, support and restorability need assessment.

At the practice

For a personal discussion

Editorially suggested question to discuss with Dr Niusha Barahmand Pour:

What might explain this mobility or tenderness on biting?

New mobility or pain on biting deserves assessment.

Learning layer for training & practiceUnderstand terminology and deepen knowledge

Occlusion: Contact between upper and lower teeth.
Periodontium: Tooth-supporting tissues.
Mobility: Movement of a tooth.

Make the distinction

Occlusion describes contacts; trauma describes tissue damage.

Knowledge questionWhat distinguishes trauma from contact?

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

Trauma involves tissue injury.
Every contact is trauma.
Contact always proves decay.

View answer

Trauma involves tissue injury.

Contact alone cannot establish the diagnosis.
