Why do newly erupted incisors have small bumps along their edges?
Mamelons are small rounded prominences along the biting edge of newly erupted permanent incisors. Three developmental bumps are typical. They belong to a young tooth's natural shape and are not, by themselves, a cavity or a broken tooth fragment.

Recognise the shape
The rounded prominences sit on the incisal edge. Their shape and prominence can differ between teeth.
Understand natural appearance
A gently wavy edge can be a normal developmental feature. Its visibility alone establishes neither disease nor a need for treatment.
Distinguish a new change
A newly sharp edge, pain or an accident should not automatically be attributed to mamelons. Such changes need assessment.

Notes on the teaching images
- Mamelons are small developmental bumps along incisal edges, particularly on newly erupted permanent incisors.
- These contours can be part of natural tooth shape. Visibility and wear vary.
- A new sharp edge or chipped area needs to be distinguished from this. Do not file teeth yourself.

Often confused
Developmental shape and fracture
Mamelons are rounded features formed during tooth development. A fracture is a loss of tooth tissue and may need examination.
Quick answers
Must the bumps be smoothed?
Not simply because they are visible. Before a purely aesthetic change, remember that removed tooth tissue does not grow back.
Can I file the edge myself?
No. DIY filing can irreversibly remove enamel, cause sensitivity and change contacts. Even small adjustments require professional judgement.
Are all uneven incisor edges mamelons?
No. Wear, small fractures and other changes can also cause uneven edges. Their history and an examination help distinguish them.
At the practice
For a personal discussion
Editorially suggested question to discuss with Dr Niusha Barahmand Pour:
Is this edge a normal tooth shape or is there a finding that needs treatment?
Does a tooth edge look unusual or has it changed? An examination can distinguish natural shape from damage.
