Definition?
Unusually large tooth size.
← All explanationsMacrodontia
When is a tooth unusually large?
Macrodontia means a tooth is larger than usual. A tooth may also merely look large because neighbouring teeth are smaller or the arch offers little space. Measurement, shape and available space help distinguish these situations.

Compare size
Assessment considers tooth type and the rest of the dentition. A photograph alone does not reliably establish size.
Assess a broad crown
Fusion of developing teeth can also explain a broad crown. It is not the same as every case of true enlargement.
Everyday relevance
Cleanability, contacts and space matter. An unusual size does not automatically require cosmetic correction.

Notes on the teaching images
- Schematic size comparison, not a measuring scale. Enlargement is assessed in the context of the whole dentition.

Do not confuse?
A broad double crown may have a different cause.
Treatment need?
Depends on function and findings.

Often confused
Truly large or relatively large?
Tooth size and available arch space are separate findings.
Quick answers
Is a large tooth diseased?
Not automatically. Shape, function and any symptoms are assessed.
Can it simply be ground smaller?
Not without planning. Uncontrolled reduction can damage tooth tissue and the pulp.
Will I need braces?
That depends on space and bite; the term alone does not determine treatment.

For a personal discussion
Editorially suggested question to discuss with Dr Niusha Barahmand Pour:
Is the tooth truly enlarged or does it only look large in proportion?
If tooth shape affects cleaning, biting or your smile, assessment can clarify the proportions and options.

- Mesiodistal width
- Width between the sides of a tooth along the arch.
- Morphology
- The shape of a structure.
- Relative size appearance
- Appearance created by neighbouring teeth and arch proportions.
