Mamelon (dentistry)

Mamelons 7y old

Mamelon refers to one of the three rounded protuberances found on the incisal edges of newly erupted permanent incisor teeth. These structures are typically present in children and young adults and are usually worn away by normal occlusion and mastication over time.

Anatomy and Function

Mamelons are composed of enamel, the hard, outermost layer of the tooth. They are most commonly observed on the central and lateral incisor teeth. The presence of mamelons is a normal part of dental development and they play a role in the initial alignment and spacing of the teeth as they erupt.

Clinical Significance

In most cases, mamelons wear down naturally as a result of regular chewing and biting activities. However, in some individuals, particularly those with malocclusion or other dental anomalies, mamelons may persist into adulthood. Persistent mamelons can be aesthetically unpleasing and may be smoothed down by a dentist if desired.
